SPCR is currently only enabled or ARM64 and x86 can use SPCR to setup
an early console.
General fixes include updating Documentation & Kconfig (for x86),
updating comments, and changing parse_spcr() to acpi_parse_spcr(),
and earlycon_init_is_deferred to earlycon_acpi_spcr_enable to be
more descriptive.
On x86, many systems have a valid SPCR table but the table version is
not 2 so the table version check must be a warning.
On ARM64 when the kernel parameter earlycon is used both the early console
and console are enabled. On x86, only the earlycon should be enabled by
by default. Modify acpi_parse_spcr() to allow options for initializing
the early console and console separately.

Pull spectre/meltdown updates from Thomas Gleixner:
"The next round of updates related to melted spectrum:
- The initial set of spectre V1 mitigations:
- Array index speculation blocker and its usage for syscall,
fdtable and the n180211 driver.
- Speculation barrier and its usage in user access functions
- Make indirect calls in KVM speculation safe
- Blacklisting of known to be broken microcodes so IPBP/IBSR are not
touched.
- The initial IBPB support and its usage in context switch
- The exposure of the new speculation MSRs to KVM guests.
- A fix for a regression in x86/32 related to the cpu entry area
- Proper whitelisting for known to be safe CPUs from the mitigations.
- objtool fixes to deal proper with retpolines and alternatives
- Exclude __init functions from retpolines which speeds up the boot
process.
- Removal of the syscall64 fast path and related cleanups and
simplifications
- Removal of the unpatched paravirt mode which is yet another source
of indirect unproteced calls.
- A new and undisputed version of the module mismatch warning
- A couple of cleanup and correctness fixes all over the place
Yet another step towards full mitigation. There are a few things still
missing like the RBS underflow mitigation for Skylake and other small
details, but that's being worked on.
That said, I'm taking a belated christmas vacation for a week and hope
that everything is magically solved when I'm back on Feb 12th"

Pull printk updates from Petr Mladek:
- Add a console_msg_format command line option:
The value "default" keeps the old "[time stamp] text\n" format. The
value "syslog" allows to see the syslog-like "<log
level>[timestamp] text" format.
This feature was requested by people doing regression tests, for
example, 0day robot. They want to have both filtered and full logs
at hands.
- Reduce the risk of softlockup:
Pass the console owner in a busy loop.
This is a new approach to the old problem. It was first proposed by
Steven Rostedt on Kernel Summit 2017. It marks a context in which
the console_lock owner calls console drivers and could not sleep.
On the other side, printk() callers could detect this state and use
a busy wait instead of a simple console_trylock(). Finally, the
console_lock owner checks if there is a busy waiter at the end of
the special context and eventually passes the console_lock to the
waiter.
The hand-off works surprisingly well and helps in many situations.
Well, there is still a possibility of the softlockup, for example,
when the flood of messages stops and the last owner still has too
much to flush.
There is increasing number of people having problems with
printk-related softlockups. We might eventually need to get better
solution. Anyway, this looks like a good start and promising
direction.
- Do not allow to schedule in console_unlock() called from printk():
This reverts an older controversial commit. The reschedule helped
to avoid softlockups. But it also slowed down the console output.
This patch is obsoleted by the new console waiter logic described
above. In fact, the reschedule made the hand-off less effective.
- Deprecate "%pf" and "%pF" format specifier:
It was needed on ia64, ppc64 and parisc64 to dereference function
descriptors and show the real function address. It is done
transparently by "%ps" and "pS" format specifier now.
Sergey Senozhatsky found that all the function descriptors were in
a special elf section and could be easily detected.
- Remove printk_symbol() API:
It has been obsoleted by "%pS" format specifier, and this change
helped to remove few continuous lines and a less intuitive old API.
- Remove redundant memsets:
Sergey removed unnecessary memset when processing printk.devkmsg
command line option.

Pull Kconfig updates from Masahiro Yamada:
"A pretty big batch of Kconfig updates.
I have to mention the lexer and parser of Kconfig are now built from
real .l and .y sources. So, flex and bison are the requirement for
building the kernel. Both of them (unlike gperf) have been stable for
a long time. This change has been tested several weeks in linux-next,
and I did not receive any problem report about this.
Summary:
- add checks for mistakes, like the choice default is not in choice,
help is doubled
- document data structure and complex code
- fix various memory leaks
- change Makefile to build lexer and parser instead of using
pre-generated C files
- drop 'boolean' keyword, which is equivalent to 'bool'
- use default 'yy' prefix and remove unneeded Make variables
- fix gettext() check for xconfig
- announce that oldnoconfig will be finally removed
- make 'Selected by:' and 'Implied by' readable in help and search
result
- hide silentoldconfig from 'make help' to stop confusing people

The 'noreplace-paravirt' option disables paravirt patching, leaving the
original pv indirect calls in place.
That's highly incompatible with retpolines, unless we want to uglify
paravirt even further and convert the paravirt calls to retpolines.
As far as I can tell, the option doesn't seem to be useful for much
other than introducing surprising corner cases and making the kernel
vulnerable to Spectre v2. It was probably a debug option from the early
paravirt days. So just remove it.

As explained by Michal Marek at https://lkml.org/lkml/2011/8/31/189
silentoldconfig has become a misnomer. It has become an internal interface
so remove it from "make help" and Documentation/ to stop confusing people
using it as seen for instance at
https://chromium-review.googlesource.com/835632 Don't remove it from
kconfig/Makefile yet not to break any (other) tool using it.
On the other hand, correct and expand its description in the help of

Pull x86 pti updates from Thomas Gleixner:
"This contains:
- a PTI bugfix to avoid setting reserved CR3 bits when PCID is
disabled. This seems to cause issues on a virtual machine at least
and is incorrect according to the AMD manual.
- a PTI bugfix which disables the perf BTS facility if PTI is
enabled. The BTS AUX buffer is not globally visible and causes the
CPU to fault when the mapping disappears on switching CR3 to user
space. A full fix which restores BTS on PTI is non trivial and will
be worked on.
- PTI bugfixes for EFI and trusted boot which make sure that the user
space visible page table entries have the NX bit cleared
- removal of dead code in the PTI pagetable setup functions
- add PTI documentation
- add a selftest for vsyscall to verify that the kernel actually
implements what it advertises.
- a sysfs interface to expose vulnerability and mitigation
information so there is a coherent way for users to retrieve the
status.
- the initial spectre_v2 mitigations, aka retpoline:
+ The necessary ASM thunk and compiler support
+ The ASM variants of retpoline and the conversion of affected ASM
code
+ Make LFENCE serializing on AMD so it can be used as speculation
trap
+ The RSB fill after vmexit
- initial objtool support for retpoline
As I said in the status mail this is the most of the set of patches
which should go into 4.15 except two straight forward patches still on
hold:
- the retpoline add on of LFENCE which waits for ACKs
- the RSB fill after context switch
Both should be ready to go early next week and with that we'll have
covered the major holes of spectre_v2 and go back to normality"

Only try to enable a 64-bit window on AMD CPUs when "pci=big_root_window"
is specified.
This taints the kernel because the new 64-bit window uses address space we
don't know anything about, and it may contain unreported devices or memory
that would conflict with the window.
The pci_amd_enable_64bit_bar() quirk that enables the window is specific to
AMD CPUs. The generic solution would be to have the firmware enable the
window and describe it in the host bridge's _CRS method, or at least
describe it in the _PRS method so the OS would have the option of enabling
it.

0day and kernelCI automatically parse kernel log - basically some sort
of grepping using the pre-defined text patterns - in order to detect
and report regressions/errors. There are several sources they get the
kernel logs from:
a) dmesg or /proc/ksmg
This is the preferred way. Because `dmesg --raw' (see later Note)
and /proc/kmsg output contains facility and log level, which greatly
simplifies grepping for EMERG/ALERT/CRIT/ERR messages.
b) serial consoles
This option is harder to maintain, because serial console messages
don't contain facility and log level.
This patch introduces a `console_msg_format=' command line option,
to switch between different message formatting on serial consoles.
For the time being we have just two options - default and syslog.
The "default" option just keeps the existing format. While the
"syslog" option makes serial console messages to appear in syslog
format [syslog() syscall], matching the `dmesg -S --raw' and
`cat /proc/kmsg' output formats:
- facility and log level
- time stamp (depends on printk_time/PRINTK_TIME)
- message
<%u>[time stamp] text\n
NOTE: while Kevin and Fengguang talk about "dmesg --raw", it's actually
"dmesg -S --raw" that always prints messages in syslog format [per
Petr Mladek]. Running "dmesg --raw" may produce output in non-syslog
format sometimes. console_msg_format=syslog enables syslog format,
thus in documentation we mention "dmesg -S --raw", not "dmesg --raw".
Per Kevin Hilman:
: Right now we can get this info from a "dmesg --raw" after bootup,
: but it would be really nice in certain automation frameworks to
: have a kernel command-line option to enable printing of loglevels
: in default boot log.
:
: This is especially useful when ingesting kernel logs into advanced
: search/analytics frameworks (I'm playing with and ELK stack: Elastic
: Search, Logstash, Kibana).
:
: The other important reason for having this on the command line is that
: for testing linux-next (and other bleeding edge developer branches),
: it's common that we never make it to userspace, so can't even run
: "dmesg --raw" (or equivalent.) So we really want this on the primary
: boot (serial) console.
Per Fengguang Wu, 0day scripts should quickly benefit from that
feature, because they will be able to switch to a more reliable
parsing, based on messages' facility and log levels [1]:
`#{grep} -a -E -e '^<[0123]>' -e '^kern :(err |crit |alert |emerg )'
instead of doing text pattern matching
`#{grep} -a -F -f /lkp/printk-error-messages #{kmsg_file} |
grep -a -v -E -f #{LKP_SRC}/etc/oops-pattern |
grep -a -v -F -f #{LKP_SRC}/etc/kmsg-blacklist`

Use a bitmap of size 0xFF instead of a u64 for the GPE mask so 256

The purpose of torture_runnable is to allow rcutorture and locktorture
to be started and stopped via sysfs when they are built into the kernel
(as in not compiled as loadable modules). However, the 0444 permissions
for both instances of torture_runnable prevent this use case from ever
being put into practice. Given that there have been no complaints
about this deficiency, it is reasonable to conclude that no one actually
makes use of this sysfs capability. The perf_runnable module parameter
for rcuperf is in the same situation.
This commit therefore removes both torture_runnable instances as well
as perf_runnable.

The ACPI code supporting system transitions to sleep states uses
an internal blacklist to apply special handling to some machines
reported to behave incorrectly in some ways.
However, some entries of that blacklist cover problematic as well as
non-problematic systems, so give the users of the latter a chance to
ignore the blacklist and run their systems in the default way by
adding acpi_sleep=nobl to the kernel command line.
For example, that allows the users of Dell XPS13 9360 systems not
affected by the issue that caused the blacklist entry for this
machine to be added by commit 71630b7a832f (ACPI / PM: Blacklist Low
Power S0 Idle _DSM for Dell XPS13 9360) to use suspend-to-idle with
the Low Power S0 Idle _DSM interface which in principle should be

Pull x86 platform driver updates from Andy Shevchenko:
"Here is the collected material against Platform Drivers x86 subsystem.
It's rather bit busy cycle for PDx86, mostly due to Dell SMBIOS driver
activity
For this cycle we have quite an update for the Dell SMBIOS driver
including WMI work to provide an interface for SMBIOS tokens via sysfs
and WMI support for 2017+ Dell laptop models. SMM dispatcher code is
split into a separate driver followed by a new WMI dispatcher. The
latter provides a character device interface to user space.
The git history also contains a merge of immutable branch from Wolfram
Sang in order to apply a dependent fix to the Intel CherryTrail
Battery Management driver.
Other Intel drivers got a lot of cleanups. The Turbo Boost Max 3.0
support is added for Intel Skylake.
Peaq WMI hotkeys driver gets its own maintainer and white list of
supported models.

GICv4 Support for KVM/ARM for v4.15
|
|
Pull powerpc updates from Michael Ellerman:
"A bit of a small release, I suspect in part due to me travelling for
KS. But my backlog of patches to review is smaller than usual, so I
think in part folks just didn't send as much this cycle.
Non-highlights:
- Five fixes for the >128T address space handling, both to fix bugs
in our implementation and to bring the semantics exactly into line
with x86.
Highlights:
- Support for a new OPAL call on bare metal machines which gives us a
true NMI (ie. is not masked by MSR[EE]=0) for debugging etc.
- Support for Power9 DD2 in the CXL driver.
- Improvements to machine check handling so that uncorrectable errors
can be reported into the generic memory_failure() machinery.
- Some fixes and improvements for VPHN, which is used under PowerVM
to notify the Linux partition of topology changes.
- Plumbing to enable TM (transactional memory) without suspend on
some Power9 processors (PPC_FEATURE2_HTM_NO_SUSPEND).
- Support for emulating vector loads form cache-inhibited memory, on
some Power9 revisions.
- Disable the fast-endian switch "syscall" by default (behind a
CONFIG), we believe it has never had any users.
- A major rework of the API drivers use when initiating and waiting
for long running operations performed by OPAL firmware, and changes
to the powernv_flash driver to use the new API.
- Several fixes for the handling of FP/VMX/VSX while processes are
using transactional memory.
- Optimisations of TLB range flushes when using the radix MMU on
Power9.
- Improvements to the VAS facility used to access coprocessors on
Power9, and related improvements to the way the NX crypto driver
handles requests.
- Implementation of PMEM_API and UACCESS_FLUSHCACHE for 64-bit.
