Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:
perf.data:
Alexey Budankov:
- Streaming compression of perf ring buffer into PERF_RECORD_COMPRESSED
user space records, resulting in ~3-5x perf.data file size reduction
on variety of tested workloads what saves storage space on larger
server systems where perf.data size can easily reach several tens or
even hundreds of GiBs, especially when profiling with DWARF-based
stacks and tracing of context switches.
perf record:
Arnaldo Carvalho de Melo
- Improve -user-regs/intr-regs suggestions to overcome errors.
perf annotate:
Jin Yao:
- Remove hist__account_cycles() from callback, speeding up branch processing
(perf record -b).
perf stat:
- Add a 'percore' event qualifier, e.g.: -e cpu/event=0,umask=0x3,percore=1/,
that sums up the event counts for both hardware threads in a core.
We can already do this with --per-core, but it's often useful to do
this together with other metrics that are collected per hardware thread.
I.e. now its possible to do this per-event, and have it mixed with other
events not aggregated by core.
core libraries:
Donald Yandt:
- Check for errors when doing fgets(/proc/version).
Jiri Olsa:
- Speed up report for perf compiled with linbunwind.
tools headers:
Arnaldo Carvalho de Melo
- Update memcpy_64.S, x86's kvm.h and pt_regs.h.
arm64:
Florian Fainelli:
- Map Brahma-B53 CPUID to cortex-a53 events.
- Add Cortex-A57 and Cortex-A72 events.
csky:
Mao Han:
- Add DWARF register mappings for libdw, allowing --call-graph=dwarf to work
on the C-SKY arch.
x86:
Andi Kleen/Kan Liang:
- Add support for recording and printing XMM registers, available, for
instance, on Icelake.
Kan Liang:
- Add uncore_upi (Intel's "Ultra Path Interconnect" events) JSON support.
UPI replaced the Intel QuickPath Interconnect (QPI) in Xeon Skylake-SP.
Intel PT:
Adrian Hunter
. Fix instructions sampling rate.
. Timestamp fixes.
. Improve exported-sql-viewer GUI, allowing, for instance, to copy'n'paste
the trees, useful for e-mailing.
Documentation:
Thomas Richter:
- Add description for 'perf --debug stderr=1', which redirects stderr to stdout.
libtraceevent:
Tzvetomir Stoyanov:

In the recent build test of linux-next, Stephen saw a build error
caused by a broken .tmp_versions/*.mod file:
https://lkml.org/lkml/2019/5/13/991
drivers/net/phy/asix.ko and drivers/net/usb/asix.ko have the same
basename, and there is a race in generating .tmp_versions/asix.mod
Kbuild has not checked this before, and it suddenly shows up with
obscure error messages when this kind of race occurs.
Non-unique module names cause various sort of problems, but it is
not trivial to catch them by eyes.
Hence, this script.
It checks not only real modules, but also built-in modules (i.e.
controlled by tristate CONFIG option, but currently compiled with =y).
Non-unique names for built-in modules also cause problems because
/sys/modules/ would fall over.
For the latest kernel, I tested "make allmodconfig all" (or more
quickly "make allyesconfig modules"), and it detected the following:
warning: same basename if the following are built as modules:
drivers/regulator/88pm800.ko

Currently menu blocks start with a pretty header but end with nothing in
the generated config. So next config options stick together with the
options from the menu block.
Let's terminate menu blocks in the generated config with a comment and
a newline if needed. Example:
...
CONFIG_BPF_STREAM_PARSER=y
CONFIG_NET_FLOW_LIMIT=y
#
# Network testing
#
CONFIG_NET_PKTGEN=y
CONFIG_NET_DROP_MONITOR=y
# end of Network testing

The 'addtree' and 'flags' in scripts/Kbuild.include are so compilecated
and ugly.
As I mentioned in [1], Kbuild should stop automatic prefixing of header
search path options.
I fixed up (almost) all Makefiles in the kernel. Now 'addtree' and
'flags' have been removed.
Kbuild still caters to add $(srctree)/$(src) and $(objtree)/$(obj)
to the header search path for O= building, but never touches extra
compiler options from ccflags-y etc.

Currently, the Kbuild core manipulates header search paths in a crazy
way [1].
To fix this mess, I want all Makefiles to add explicit $(srctree)/ to
the search paths in the srctree. Some Makefiles are already written in
that way, but not all. The goal of this work is to make the notation
consistent, and finally get rid of the gross hacks.
Having whitespaces after -I does not matter since commit 48f6e3cf5bc6

As of Linux 5.1, alpha and s390 are the last architectures that
have defconfig in arch/*/ instead of arch/*/configs/.
$ find arch -name defconfig | sort
arch/alpha/defconfig
arch/arm64/configs/defconfig
arch/csky/configs/defconfig
arch/nds32/configs/defconfig
arch/riscv/configs/defconfig
arch/s390/defconfig
The arch/$(ARCH)/defconfig is the hard-coded default in Kconfig,
and I want to deprecate it after evacuating the remaining defconfig
into the standard location, arch/*/configs/.
Define KBUILD_DEFCONFIG like other architectures, and move defconfig

syncconfig is responsible for keeping auto.conf up-to-date, so if it
fails for any reason, the build must be terminated immediately.
However, since commit 9390dff66a52 ("kbuild: invoke syncconfig if
include/config/auto.conf.cmd is missing"), Kbuild continues running
even after syncconfig fails.
You can confirm this by intentionally making syncconfig error out:
diff --git a/scripts/kconfig/confdata.c b/scripts/kconfig/confdata.c
index 08ba146..307b9de 100644
--- a/scripts/kconfig/confdata.c

FILE *out, *tristate, *out_h;
int i;
+ if (overwrite)
+ return 1;
+
if (!overwrite && is_present(autoconf_name))
return 0;
Then, syncconfig fails, but Make would not stop:
$ make -s mrproper allyesconfig defconfig
$ make
scripts/kconfig/conf --syncconfig Kconfig
*** Error during sync of the configuration.
make[2]: *** [scripts/kconfig/Makefile;69: syncconfig] Error 1

The reason is in the behavior of a pattern rule with multi-targets.
%/auto.conf %/auto.conf.cmd %/tristate.conf: $(KCONFIG_CONFIG)
$(Q)$(MAKE) -f $(srctree)/Makefile syncconfig
GNU Make knows this rule is responsible for making all the three files
simultaneously. As far as examined, auto.conf.cmd is the target in
question when this rule is invoked. It is probably because auto.conf.cmd
is included below the inclusion of auto.conf.
The inclusion of auto.conf is mandatory, while that of auto.conf.cmd
is optional. GNU Make does not care about the failure in the process
of updating optional include files.
I filed this issue (https://savannah.gnu.org/bugs/?56301) in case this
behavior could be improved somehow in future releases of GNU Make.
Anyway, it is quite easy to fix our Makefile.
Given that auto.conf is already a mandatory include file, there is no
reason to stick auto.conf.cmd optional. Make it mandatory as well.

arch/sh/boot/.gitignore has the pattern "vmlinux*"; this is effective
not only for the current directory, but also for any sub-directories.
So, from the point of .gitignore grammar, the following check-in files
are also considered to be ignored:
arch/sh/boot/compressed/vmlinux.scr
arch/sh/boot/romimage/vmlinux.scr
As the manual gitignore(5) says "Files already tracked by Git are not
affected", this is not a problem as far as Git is concerned.
However, Git is not the only program that parses .gitignore because
.gitignore is useful to distinguish build artifacts from source files.
For example, tar(1) supports the --exclude-vcs-ignore option. As of
writing, this option does not work perfectly, but it intends to create
a tarball excluding files specified by .gitignore.
So, I believe it is better to fix this issue.

flow to VF0 (PF2) would be determined as same destination. It lead

imply it in mlx5_core to make it always reachable if it was enabled.

Error message printed:
modprobe: ERROR: could not insert 'tipc': Address family not
supported by protocol.
when modprobe tipc after the following patch: switch order of
device registration, commit 7e27e8d6130c
("tipc: switch order of device registration to fix a crash")
Because sock_create_kern(net, AF_TIPC, ...) is called by
tipc_topsrv_create_listener() in the initialization process
of tipc_net_ops, tipc_socket_init() must be execute before that.
I move tipc_socket_init() into function tipc_init_net().

Because the function snprintf write at most size bytes(including the
null byte).So the value of the argument size need not to minus one.

i2c_new_dummy is typically called from the probe function of the
driver for the primary i2c client. It requires calls to
i2c_unregister_device in the error path of the probe function and
in the remove function.
This can be simplified by introducing a device-managed version.
Note the changed error case return value type: i2c_new_dummy returns
NULL whilst devm_i2c_new_dummy_device returns an ERR_PTR.

Currently i2c_new_device and i2c_new_dummy return just NULL in error
case although they have more error details internally. Therefore move
the functionality into new functions returning detailed errors and
add wrappers for compatibility with the current API.
This allows to use these functions with detailed error codes within
the i2c core or for API extensions.
