<title>arm64: Replace __ASSEMBLY__ with __ASSEMBLER__ in non-uapi headers</title>

<id>urn:sha1:287d163322b743a50adcad25c851600c004f59e3</id>
<content type='text'>
While the GCC and Clang compilers already define __ASSEMBLER__
automatically when compiling assembly code, __ASSEMBLY__ is a
macro that only gets defined by the Makefiles in the kernel.
This can be very confusing when switching between userspace
and kernelspace coding, or when dealing with uapi headers that
rather should use __ASSEMBLER__ instead. So let's standardize now
on the __ASSEMBLER__ macro that is provided by the compilers.

This is a mostly mechanical patch (done with a simple "sed -i"
statement), except for the following files where comments with
mis-spelled macros were tweaked manually:

 arch/arm64/include/asm/stacktrace/frame.h
 arch/arm64/include/asm/kvm_ptrauth.h
 arch/arm64/include/asm/debug-monitors.h
 arch/arm64/include/asm/esr.h
 arch/arm64/include/asm/scs.h
 arch/arm64/include/asm/memory.h

One difference here with other pseudo-firmware bitmap registers
is that the default/reset value for the supported hypercall
function-ids is 0 at present. Hence, modify the test accordingly.

<title>tools headers: Update tools's copy of arm64/asm headers</title>

<link rel='alternate' type='text/html' href='https://universe.0xinfinity.dev/distro/kernel/commit/?id=fad8afdcc18ff72e1d90c558be364f26534b8a5b'/>
<id>urn:sha1:fad8afdcc18ff72e1d90c558be364f26534b8a5b</id>
<content type='text'>
tldr; Just FYI, I'm carrying this on the perf tools tree.

Full explanation:

There used to be no copies, with tools/ code using kernel headers
directly. From time to time tools/perf/ broke due to legitimate kernel
hacking. At some point Linus complained about such direct usage. Then we
adopted the current model.

The way these headers are used in perf are not restricted to just
including them to compile something.

There are sometimes used in scripts that convert defines into string
tables, etc, so some change may break one of these scripts, or new MSRs
may use some different #define pattern, etc.

E.g.:

  $ ls -1 tools/perf/trace/beauty/*.sh | head -5
  tools/perf/trace/beauty/arch_errno_names.sh
  tools/perf/trace/beauty/drm_ioctl.sh
  tools/perf/trace/beauty/fadvise.sh
  tools/perf/trace/beauty/fsconfig.sh
  tools/perf/trace/beauty/fsmount.sh
  $
  $ tools/perf/trace/beauty/fadvise.sh
  static const char *fadvise_advices[] = {
        [0] = "NORMAL",
        [1] = "RANDOM",
        [2] = "SEQUENTIAL",
        [3] = "WILLNEED",
        [4] = "DONTNEED",
        [5] = "NOREUSE",
  };
  $

The tools/perf/check-headers.sh script, part of the tools/ build
process, points out changes in the original files.

So its important not to touch the copies in tools/ when doing changes in
the original kernel headers, that will be done later, when
check-headers.sh inform about the change to the perf tools hackers.
