Ben Hutchings 95363747a6 tools/include/uapi: Fix <asm/errno.h> for parisc and xtensa 
tools/include/uapi/asm/errno.h currently attempts to include
non-existent arch-specific errno.h header for xtensa.
Remove this case so that <asm-generic/errno.h> is used instead,
and add the missing arch-specific header for parisc.

John Paul Adrian Glaubitz 17786fea41 ia64: tools: remove inclusion of ia64-specific version of errno.h header 
There is no longer an ia64-specific version of the errno.h header below
arch/ia64/include/uapi/asm/, so trying to build tools/bpf fails with:

    CC       /usr/src/linux/tools/bpf/bpftool/btf_dumper.o
  In file included from /usr/src/linux/tools/include/linux/err.h:8,
                   from btf_dumper.c:11:
  /usr/src/linux/tools/include/uapi/asm/errno.h:13:10: fatal error: ../../../arch/ia64/include/uapi/asm/errno.h: No such file or directory
     13 | #include "../../../arch/ia64/include/uapi/asm/errno.h"
        |          ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  compilation terminated.

Thus, just remove the inclusion of the ia64-specific errno.h so that the
build will use the generic errno.h header on this target which was used
there anyway as the ia64-specific errno.h was just a wrapper for the
generic header.

Ian Rogers 441b62acd9 tools: Fix off-by 1 relative directory includes 
This is currently working due to extra include paths in the build.

Committer testing:

  $ cd tools/include/uapi/asm/

Before this patch:

  $ ls -la ../../arch/x86/include/uapi/asm/errno.h
  ls: cannot access '../../arch/x86/include/uapi/asm/errno.h': No such file or directory
  $

After this patch;

  $ ls -la ../../../arch/x86/include/uapi/asm/errno.h
  -rw-rw-r--. 1 acme acme 31 Feb 20 12:42 ../../../arch/x86/include/uapi/asm/errno.h
  $

Check that that is still under tools/, i.e. hasn't escaped into the main
kernel sources:

  $ cd ../../../arch/x86/include/uapi/asm/
  $ pwd
  /home/acme/git/perf/tools/arch/x86/include/uapi/asm
  $

Sirio Balmelli cd65cd9512 selftests/bpf: add architecture-agnostic headers 
The BPF selftests fail to build with missing headers
'asm/bitsperlong.h' and 'asm/errno.h'.

These already exist in 'tools/arch/[arch]/include';
add architecture-agnostic header files in 'tools/include/uapi'
to reference them.
