Pull perf tooling fixes from Ingo Molnar: "These are all perf tooling changes: most of them are fixes. Note that the large CPU count related fixes go beyond regression fixes, but the IPI-flood symptoms are severe enough that I think justifies their inclusion" * 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (38 commits) perf vendor events s390: Remove name from L1D_RO_EXCL_WRITES description perf vendor events s390: Fix counter long description for DTLB1_GPAGE_WRITES libtraceevent: Allow custom libdir path perf header: Fix false warning when there are no duplicate cache entries perf metricgroup: Fix printing event names of metric group with multiple events perf/x86/pmu-events: Fix Kernel_Utilization metric perf top: Do not bail out when perf_env__read_cpuid() returns ENOSYS perf arch: Make the default get_cpuid() return compatible error tools headers kvm: Sync linux/kvm.h with the kernel sources tools headers UAPI: Update tools's copy of drm.h headers tools headers UAPI: Sync drm/i915_drm.h with the kernel sources perf inject: Fix processing of ID index for injected instruction tracing perf report: Bail out --mem-mode if mem info is not available perf report: Make -F more strict like -s perf report/top TUI: Replace pr_err() with ui__error() libtraceevent: Copy pkg-config file to output folder when using O= libtraceevent: Fix lib installation with O= perf kvm: Clarify the 'perf kvm' -i and -o command line options tools arch x86: Sync asm/cpufeatures.h with the kernel sources perf beauty: Add CLEAR_SIGHAND support for clone's flags arg ...
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
