Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:

perf script:

  Adrian Hunter:

  - Fix brstackinsn for AUXTRACE.

  - Fix invalid LBR/binary mismatch error.

perf diff:

  Arnaldo Carvalho de Melo:

  - Use llabs() with 64-bit values, fixing the build in some 32-bit
    architectures.

perf pmu:

  Andi Kleen:

  - Use file system cache to optimize sysfs access.

x86:

  Adrian Hunter:

  - Add some more Intel instructions to the opcode map and to the perf
    test entry:

      gf2p8affineinvqb, gf2p8affineqb, gf2p8mulb, v4fmaddps,
      v4fmaddss, v4fnmaddps, v4fnmaddss, vaesdec, vaesdeclast, vaesenc,
      vaesenclast, vcvtne2ps2bf16, vcvtneps2bf16, vdpbf16ps,

perf affinity:

  Andi Kleen:

  - Add infrastructure to save/restore affinity

perf maps:

  - Merge 'struct maps' with 'struct map_groups', as there is a
    1x1 relationship, simplifying code overal.

perf build:

  Jiri Olsa:

  - Allow to link with libbpf dynamicaly.

Pull x86 asm updates from Ingo Molnar:
 "The main changes in this cycle were:

   - Cross-arch changes to move the linker sections for NOTES and
     EXCEPTION_TABLE into the RO_DATA area, where they belong on most
     architectures. (Kees Cook)

   - Switch the x86 linker fill byte from x90 (NOP) to 0xcc (INT3), to
     trap jumps into the middle of those padding areas instead of
     sliding execution. (Kees Cook)

   - A thorough cleanup of symbol definitions within x86 assembler code.
     The rather randomly named macros got streamlined around a
     (hopefully) straightforward naming scheme:

        SYM_START(name, linkage, align...)
        SYM_END(name, sym_type)

        SYM_FUNC_START(name)

        SYM_DATA_END(name)

     etc - with about three times of these basic primitives with some
     label, local symbol or attribute variant, expressed via postfixes.

     No change in functionality intended. (Jiri Slaby)

<id>b980be189c9badba50634671e2303e92bf28e35a</id>

Add to the opcode map the following instructions:
        cldemote
        tpause
        umonitor
        umwait
        movdiri
        movdir64b
        enqcmd
        enqcmds
        encls
        enclu
        enclv
        pconfig
        wbnoinvd

For information about the instructions, refer Intel SDM May 2019
(325462-070US) and Intel Architecture Instruction Set Extensions
May 2019 (319433-037).

The instruction decoding can be tested using the perf tools'
"x86 instruction decoder - new instructions" test as folllows:

These are all functions which are invoked from elsewhere, so annotate
them as global using the new SYM_FUNC_START and their ENDPROC's by
SYM_FUNC_END.

Now, ENTRY/ENDPROC can be forced to be undefined on X86, so do so.

These are all functions which are invoked from elsewhere, so annotate
them as global using the new SYM_FUNC_START and their ENDPROC's by
SYM_FUNC_END.

Make sure ENTRY/ENDPROC is not defined on X86_64, given these were the
last users.

There are a couple of assembly functions which are invoked only locally
in the file they are defined. In C, they are marked "static". In
assembly, annotate them using SYM_{FUNC,CODE}_START_LOCAL (and switch
their ENDPROC to SYM_{FUNC,CODE}_END too). Whether FUNC or CODE is used,
depends on whether ENDPROC or END was used for a particular function
before.

<title>x86/asm: Annotate aliases</title>

_key_expansion_128 is an alias to _key_expansion_256a, __memcpy to
memcpy, xen_syscall32_target to xen_sysenter_target, and so on. Annotate
them all using the new SYM_FUNC_START_ALIAS, SYM_FUNC_START_LOCAL_ALIAS,
and SYM_FUNC_END_ALIAS. This will make the tools generating the
debuginfo happy as it avoids nesting and double symbols.
