This patch introduces SO_TXTIME. User space enables this option in
order to pass a desired future transmit time in a CMSG when calling
sendmsg(2). The argument to this socket option is a 8-bytes long struct
provided by the uapi header net_tstamp.h defined as:
struct sock_txtime {
clockid_t clockid;
u32 flags;
};
Note that new fields were added to struct sock by filling a 2-bytes
hole found in the struct. For that reason, neither the struct size or
number of cachelines were altered.

Originally in patch e6d20c55a4 ("openrisc: entry: Fix delay slot
detection") I fixed delay slot detection, but only for QEMU. We missed
that hardware delay slot detection using delay slot exception flag (DSX)
was still broken. This was because QEMU set the DSX flag in both
pre-exception supervision register (ESR) and supervision register (SR)
register, but on real hardware the DSX flag is only set on the SR
register during exceptions.
Fix this by carrying the DSX flag into the SR register during exception.
We also update the DSX flag read locations to read the value from the SR
register not the pt_regs SR register which represents ESR. The ESR
should never have the DSX flag set.
In the process I updated/removed a few comments to match the current
state. Including removing a comment saying that the DSX detection logic
was inefficient and needed to be rewritten.
I have tested this on QEMU with a patch ensuring it matches the hardware
specification.

Daniel Borkmann says:
====================
pull-request: bpf 2018-07-01
The following pull-request contains BPF updates for your *net* tree.
The main changes are:
1) A bpf_fib_lookup() helper fix to change the API before freeze to
return an encoding of the FIB lookup result and return the nexthop
device index in the params struct (instead of device index as return
code that we had before), from David.
2) Various BPF JIT fixes to address syzkaller fallout, that is, do not
reject progs when set_memory_*() fails since it could still be RO.
Also arm32 JIT was not using bpf_jit_binary_lock_ro() API which was
an issue, and a memory leak in s390 JIT found during review, from
Daniel.
3) Multiple fixes for sockmap/hash to address most of the syzkaller
triggered bugs. Usage with IPv6 was crashing, a GPF in bpf_tcp_close(),
a missing sock_map_release() routine to hook up to callbacks, and a
fix for an omitted bucket lock in sock_close(), from John.
4) Two bpftool fixes to remove duplicated error message on program load,
and another one to close the libbpf object after program load. One
additional fix for nfp driver's BPF offload to avoid stopping offload
completely if replace of program failed, from Jakub.
5) Couple of BPF selftest fixes that bail out in some of the test
scripts if the user does not have the right privileges, from Jeffrin.
6) Fixes in test_bpf for s390 when CONFIG_BPF_JIT_ALWAYS_ON is set
where we need to set the flag that some of the test cases are expected
to fail, from Kleber.
7) Fix to detangle BPF_LIRC_MODE2 dependency from CONFIG_CGROUP_BPF
since it has no relation to it and lirc2 users often have configs
without cgroups enabled and thus would not be able to use it, from Sean.
8) Fix a selftest failure in sockmap by removing a useless setrlimit()
call that would set a too low limit where at the same time we are
already including bpf_rlimit.h that does the job, from Yonghong.
9) Fix BPF selftest config with missing missing NET_SCHED, from Anders.

If we would ever fail in the bpf_jit_prog() pass that writes the
actual insns to the image after we got header via bpf_jit_binary_alloc()
then we also need to make sure to free it through bpf_jit_binary_free()
again when bailing out. Given we had prior bpf_jit_prog() passes to
initially probe for clobbered registers, program size and to fill in
addrs arrray for jump targets, this is more of a theoretical one,
but at least make sure this doesn't break with future changes.

According to kernel bisection, this problem became visible due to commit
f7f99100d8d9 ("mm: stop zeroing memory during allocation in vmemmap")
which changes how struct pages are initialized.
Memblock layout affects the pfn ranges covered by node/zone. Consider
that we have a VM with 2 NUMA nodes and each node has 4GB memory, and
the default (no memmap= given) memblock layout is like below:
MEMBLOCK configuration:
memory size = 0x00000001fff75c00 reserved size = 0x000000000300c000
memory.cnt = 0x4
memory[0x0] [0x0000000000001000-0x000000000009efff], 0x000000000009e000 bytes on node 0 flags: 0x0
memory[0x1] [0x0000000000100000-0x00000000bffd6fff], 0x00000000bfed7000 bytes on node 0 flags: 0x0
memory[0x2] [0x0000000100000000-0x000000013fffffff], 0x0000000040000000 bytes on node 0 flags: 0x0
memory[0x3] [0x0000000140000000-0x000000023fffffff], 0x0000000100000000 bytes on node 1 flags: 0x0
...
If you give memmap=1G!4G (so it just covers memory[0x2]),
the range [0x100000000-0x13fffffff] is gone:
MEMBLOCK configuration:
memory size = 0x00000001bff75c00 reserved size = 0x000000000300c000
memory.cnt = 0x3
memory[0x0] [0x0000000000001000-0x000000000009efff], 0x000000000009e000 bytes on node 0 flags: 0x0
memory[0x1] [0x0000000000100000-0x00000000bffd6fff], 0x00000000bfed7000 bytes on node 0 flags: 0x0
memory[0x2] [0x0000000140000000-0x000000023fffffff], 0x0000000100000000 bytes on node 1 flags: 0x0
...
This causes shrinking node 0's pfn range because it is calculated by the
address range of memblock.memory. So some of struct pages in the gap
range are left uninitialized.
We have a function zero_resv_unavail() which does zeroing the struct pages
within the reserved unavailable range (i.e. memblock.memory &&
!memblock.reserved). This patch utilizes it to cover all unavailable
ranges by putting them into memblock.reserved.

Convert printk(KERN_LEVEL) type of calls to pr_lvl() macros.
While here,
- convert printk() to pr_info()
- join back string literal to be on one line
- use %*phN (note, it gives 1 byte more for sake of simplicity)

meson-gxl-mali.dtsi is only used on GXL SoCs. Thus it should use the GXL
specific compatible string instead of the GXBB one.
For now this is purely cosmetic since the (out-of-tree) lima driver for
this GPU currently uses the "arm,mali-450" match instead of the SoC
specific one. However, update the .dts to match the documentation since
this driver behavior might change in the future.

Like the odroid-c2 and wetek, the s400 uses the RTL8211F and seems to
suffer from the kind of stability issue.
Doing an iperf3 download test, we can see a significant number of LPI
interrupts on the tx path. After a short while (5 to 15 seconds), the
network connection dies. If using rootfs over NFS, the connection may
also break during the boot sequence.
We still don't have a real explanation for this problem so let's disable
EEE once again.

There is a problem with the sd-uhs mode when doing a soft reboot.
Switching back from 1.8v to 3.3v messes with the card, which no longer
respond (timeout errors). According to the specification, we should
perform a card reset (power cycling the card) but this is something we
cannot control on this design.
Then the only solution to restore the communication with the card is an
"unplug-plug" which is not acceptable
Until we find a solution, if any, disable the sd-uhs modes on this design.
For the people using uhs at the moment, there will a performance drop as
a result.

fixed a reported issue with fixmap page-table entries not being visible
to the walker due to a missing DSB instruction. At the same time, it added
ISB instructions to the arm64 set_{pte,pmd,pud} functions, which are not
required by the architecture and make little sense in isolation.
Remove the redundant ISBs.

The implementation of flush_icache_range() includes instruction sequences
which are themselves patched at runtime, so it is not safe to call from
the patching framework.
This patch reworks the alternatives cache-flushing code so that it rolls
its own internal D-cache maintenance using DC CIVAC before invalidating
the entire I-cache after all alternatives have been applied at boot.
Modules don't cause any issues, since flush_icache_range() is safe to
call by the time they are loaded.

This reverts the following commits:
1ea66554d3b0 ("x86/mm: Mark p4d_offset() __always_inline")
046c0dbec023 ("x86: Mark native_set_p4d() as __always_inline")
p4d_offset(), native_set_p4d() and native_p4d_clear() were marked
__always_inline in attempt to move __pgtable_l5_enabled into __initdata
section.
It was required as KASAN initialization code is a user of
USE_EARLY_PGTABLE_L5, so all pgtable_l5_enabled() translated to
__pgtable_l5_enabled there. This includes pgtable_l5_enabled() called
from inline p4d helpers.
If compiler would decided to not inline these p4d helpers, but leave
them standalone, we end up with section mismatch.
We don't need __always_inline here anymore. __pgtable_l5_enabled moved
back to be __ro_after_init. See the following commit:

Commit:
8bb2610bc496 ("x86/entry/64/compat: Preserve r8-r11 in int $0x80")
was busted: my original patch had a minor conflict with
some of the nospec changes, but "git apply" is very clever
and silently accepted the patch by making the same changes
to a different function in the same file. There was obviously
a huge offset, but "git apply" for some reason doesn't feel
any need to say so.
Move the changes to the correct function. Now the
test_syscall_vdso_32 selftests passes.
If anyone cares to observe the original problem, try applying the
patch at:
https://lore.kernel.org/lkml/d4c4d9985fbe64f8c9e19291886453914b48caee.1523975710.git.luto@kernel.org/raw
to the kernel at 316d097c4cd4e7f2ef50c40cff2db266593c4ec4:
- "git am" and "git apply" accept the patch without any complaints at all
- "patch -p1" at least prints out a message about the huge offset.

As Mathieu pointed out, my conversion to time64_t was incorrect and
resulted in negative times to be read from the RTC. The problem is
that during the conversion from a byte array to a time64_t, the
'unsigned char' variable holding the top byte gets turned into a
negative signed 32-bit integer before being assigned to the 64-bit
variable for any times after 1972.
This changes the logic to cast to an unsigned 32-bit number first for
the Macintosh time and then convert that to the Unix time, which then
gives us a time in the documented 1904..2040 year range. I decided not
to use the longer 1970..2106 range that other drivers use, for
consistency with the literal interpretation of the register, but that
could be easily changed if we decide we want to support any Mac after
2040.
Just to be on the safe side, I'm also adding a WARN_ON that will
trigger if either the year 2040 has come and is observed by this
driver, or we run into an RTC that got set back to a pre-1970 date for
some reason (the two are indistinguishable).
For the RTC write functions, Andreas found another problem: both
pmu_request() and cuda_request() are varargs functions, so changing
the type of the arguments passed into them from 32 bit to 64 bit
breaks the API for the set_rtc_time functions. This changes it back to
32 bits.
The same code exists in arch/m68k/ and is patched in an identical way
now in a separate patch.

Commit 51bc085d6454 ("PCI: Improve host drivers compile test coverage")
added configuration options to allow PCI host controller drivers to be
compile tested on all architectures.
Some host controller drivers (eg PCIE_ALTERA) config entries select the
PCI_DOMAINS config option to enable PCI domains management in the kernel.
Now that host controller drivers can be compiled on all architectures, this
triggers build regressions on arches that do not implement the PCI_DOMAINS
required API (ie pci_domain_nr()):
drivers/ata/pata_ali.c: In function 'ali_init_chipset':
drivers/ata/pata_ali.c:469:38: error: implicit declaration of function 'pci_domain_nr'; did you mean 'pci_iomap_wc'?
Furthemore, some software configurations (ie Jailhouse) require a
PCI_DOMAINS enabled kernel to configure multiple host controllers without
having an explicit dependency on the ARM platform on which they run.
Make PCI_DOMAINS a visible configuration option on ARM so that software
configurations that need it can manually select it and move the PCI_DOMAINS
selection from PCI controllers configuration file to ARM sub-arch config
entries that currently require it, fixing the issue.
