libtraceevent: Allow custom libdir path
When I use prefix=/usr and try to install libtraceevent in my laptop it tries to install in /usr/lib64. I am not having any folder as /usr/lib64 and also the debian policy doesnot allow installing in /usr/lib64. It should be in /usr/lib/x86_64-linux-gnu/. Quote: No package for a 64 bit architecture may install files in /usr/lib64/ or in a subdirectory of it. ref: https://www.debian.org/doc/debian-policy/ch-opersys.html Make it more flexible by allowing to mention libdir_relative while installing so that distros can mention the path according to their policy or use the default one.

perf header: Fix false warning when there are no duplicate cache entries
Before this patch, perf expected that there might be NPROC*4 unique cache entries at max, however, it also expected that some of them would be shared and/or of the same size, thus the final number of entries would be reduced to be lower than NPROC*4. In case the number of entries hadn't been reduced (was NPROC*4), the warning was printed. However, some systems might have unusual cache topology, such as the following two-processor KVM guest: cpu level shared_cpu_list size 0 1 0 32K 0 1 0 64K 0 2 0 512K 0 3 0 8192K 1 1 1 32K 1 1 1 64K 1 2 1 512K 1 3 1 8192K This KVM guest has 8 (NPROC*4) unique cache entries, which used to make perf printing the message, although there actually aren't "way too many cpu caches". v2: Removing unused argument. v3: Unifying the way we obtain number of cpus. v4: Removed '& UINT_MAX' construct which is redundant.

perf top: Do not bail out when perf_env__read_cpuid() returns ENOSYS
'perf top' stopped working on hw architectures that do not provide a
get_cpuid() implementation and thus fallback to the weak get_cpuid()
default function.
This is done because at annotation time we may need it in the arch
specific annotation init routine, but that is only being used by arches
that do provide a get_cpuid() implementation:
$ find tools/ -name "*.[ch]" | xargs grep 'evlist->env'
tools/perf/builtin-top.c: top.evlist->env = &perf_env;
tools/perf/util/evsel.c: return evsel->evlist->env;
tools/perf/util/s390-cpumsf.c: sf->machine_type = s390_cpumsf_get_type(session->evlist->env->cpuid);
tools/perf/util/header.c: session->evlist->env = &header->env;
tools/perf/util/sample-raw.c: const char *arch_pf = perf_env__arch(evlist->env);
$
$ find tools/perf/arch -name "*.[ch]" | xargs grep -w get_cpuid
tools/perf/arch/x86/util/auxtrace.c: ret = get_cpuid(buffer, sizeof(buffer));
tools/perf/arch/x86/util/header.c:get_cpuid(char *buffer, size_t sz)
tools/perf/arch/powerpc/util/header.c:get_cpuid(char *buffer, size_t sz)
tools/perf/arch/s390/util/header.c: * Implementation of get_cpuid().
tools/perf/arch/s390/util/header.c:int get_cpuid(char *buffer, size_t sz)
tools/perf/arch/s390/util/header.c: if (buf && get_cpuid(buf, 128))
$
For 'report' or 'script', i.e. tools working on perf.data files, that is
setup while reading the header, its just top that needs to explicitely
read it at tool start.

perf arch: Make the default get_cpuid() return compatible error
Some of the functions calling get_cpuid() propagate back the error it returns, and all are using errno (positive) values, make the weak default get_cpuid() function return ENOSYS to be consistent and to allow checking if this is an arch not providing this function or if a provided one is having trouble getting the cpuid, to decide if the warning should be provided to the user or just a debug message should be emitted.

selftests/bpf: De-flake test_tcpbpf
It looks like BPF program that handles BPF_SOCK_OPS_STATE_CB state
can race with the bpf_map_lookup_elem("global_map"); I sometimes
see the failures in this test and re-running helps.
Since we know that we expect the callback to be called 3 times (one
time for listener socket, two times for both ends of the connection),
let's export this number and add simple retry logic around that.
Also, let's make EXPECT_EQ() not return on failure, but continue
evaluating all conditions; that should make potential debugging
easier.
With this fix in place I don't observe the flakiness anymore.

perf report: Bail out --mem-mode if mem info is not available
If perf.data is recorded without -d, don't allow user to use --mem-mode
with 'perf report'. symbol_daddr and phys_daddr can be recorded
separately and may be present in the perf.data but at the report time
they are associated with mem-mode fields and thus this restriction
applies to them as well.
Before:
$ perf record ls
$ perf report --mem-mode --stdio
# Overhead Local Weight Memory access Symbol
# ........ ............ ............. .......................

perf kvm: Clarify the 'perf kvm' -i and -o command line options
The 'perf kvm' subcommand has options that it in turn passes to other perf subcommands such as 'report' and 'record', particularly -i and -o end up setting the same variable that will then be used for 'record's -o and report '-i', which ends up being confusing, leading some to think that both -i and -o can be used with 'report'. Improve the man page to state that -i is used with the post-processing subcommands while -o is used just with 'record' and that to save the output of 'report' one should simply redirect its output to a file. Noticed while reading the https://www.linux-kvm.org/page/Perf_events page.

perf beauty: Add CLEAR_SIGHAND support for clone's flags arg
Add support for the recently added CLONE_CLEAR_SIGHAND flag. This takes advantage of the copy of the uapi/linux/sched.h we have in tools/include, which allows us to build tools/perf in older systems and have the binary support printing that flag whenever that system gets its kernel updated to one where this feature is present.

libbpf: Fix readelf output parsing on powerpc with recent binutils
On powerpc with recent versions of binutils, readelf outputs an extra
field when dumping the symbols of an object file. For example:
35: 0000000000000838 96 FUNC LOCAL DEFAULT [<localentry>: 8] 1 btf_is_struct
The extra "[<localentry>: 8]" prevents the GLOBAL_SYM_COUNT variable to
be computed correctly and causes the check_abi target to fail.
Fix that by looking for the symbol name in the last field instead of the
8th one. This way it should also cope with future extra fields.

selftests: vm: add fragment CONFIG_TEST_VMALLOC
When running test_vmalloc.sh smoke the following print out states that
the fragment is missing.
# ./test_vmalloc.sh: You must have the following enabled in your kernel:
# CONFIG_TEST_VMALLOC=m
Rework to add the fragment 'CONFIG_TEST_VMALLOC=m' to the config file.

memfd: add test for COW on MAP_PRIVATE and F_SEAL_FUTURE_WRITE mappings
In this test, the parent and child both have writable private mappings. The test shows that without the patch in this series, the parent and child shared the same memory which is incorrect. In other words, COW needs to be triggered so any writes to child's copy stays local to the child.

powerpc updates for 5.5
Highlights:
- Infrastructure for secure boot on some bare metal Power9 machines. The
firmware support is still in development, so the code here won't actually
activate secure boot on any existing systems.
- A change to xmon (our crash handler / pseudo-debugger) to restrict it to
read-only mode when the kernel is lockdown'ed, otherwise it's trivial to drop
into xmon and modify kernel data, such as the lockdown state.
- Support for KASLR on 32-bit BookE machines (Freescale / NXP).
- Fixes for our flush_icache_range() and __kernel_sync_dicache() (VDSO) to work
with memory ranges >4GB.
- Some reworks of the pseries CMM (Cooperative Memory Management) driver to
make it behave more like other balloon drivers and enable some cleanups of
generic mm code.
- A series of fixes to our hardware breakpoint support to properly handle
unaligned watchpoint addresses.
Plus a bunch of other smaller improvements, fixes and cleanups.

selftests: pmtu: use -oneline for ip route list cache
Some versions of iproute2 will output more than one line per entry, which
will cause the test to fail, like:
TEST: ipv6: list and flush cached exceptions [FAIL]
can't list cached exceptions
That happens, for example, with iproute2 4.15.0. When using the -oneline
option, this will work just fine:
TEST: ipv6: list and flush cached exceptions [ OK ]
This also works just fine with a more recent version of iproute2, like
5.4.0.
For some reason, two lines are printed for the IPv4 test no matter what
version of iproute2 is used. Use the same -oneline parameter there instead
of counting the lines twice.
