[PATCH 0/5] Remove sysdep-cancel assembly macro

[Adhemerval Zanella <adhemerval dot zanella at linaro dot org>]

This patchset finishes my previous work of Linux syscall consolidation
and refactor to finally remove the requeriment of sysdeps-cancel.h
assembly macros for cancellable syscalls.  All ports now uses the
SYSCALL_CANCEL macros with C implementation which in turn calls
INLINE_SYSCALL macros.

Besides simplify the curent code requirement, it also simplify
possible future ports to require only the C bindings and the direct
assembly one for syscalls.list autogeneration (another possible
work for future would be to use C generate binding to simplify
even further the syscall requirements).

I checked with a build for mostly supported architecture:
aarch64-linux-gnu, alpha-linux-gnu, arm-linux-gnueabhi, i686-linux-gnu,
ia64-linux-gnu, m68k-linux-gnu, microblaze-linux-gnu,
mips{64,64n32}-linux-gnu, nios2-linux-gnu, powerpc{64,64le}-linux-gnu,
s390{x}-linux-gnu, sh4-linux-gnu{-soft}, tile{pro,gx}-linux-gnu{-32},
sparc{v9,64}-linux-gnu, and x86_64-linux-gnu.

I also run a full make check on real hardware on aarch64-linux-gnu,
arm-linux-gnueabihf, i686-linux-gnu, powerpc{64le}-linux-gnu,
sparc{v9,64}-linux-gnu, and x86_64-linux-gnu{-x32}.

Adhemerval Zanella (5):
  Fix {INLINE,INTERNAL}_SYSCALL macros for x32
  Remove p{read,write}{v} and fallocate from x86 auto-generation list
  linux: Consolidate sync_file_range implementation
  Consolidate Linux fcntl implementation
  Remove cancellation support for syscall generation
