This patch removes the __ASSUME_OFF_DIFF_OFF64 define introduced in
p{read,write} consolidation patch. This define was added based on
the idea 32 bits ports would continue to follow previous off{64}_t
definition where off_t size differs from off64_t one.
However, with recent AArch64/ILP32 patch submission and also with
discussion for RISCV kernel interface, 32 bits ports now may aim
to use off_t and off64_t with the same size as 64 bits.
So current assumption for both p{read,write} and p{read,write}v
are not compatible with new type definition. This patch now makes
the syscall wrappers to only depend on __OFF_T_MATCHES_OFF64_T to
define the default and 64-suffix variant, as follow:
<function>.c
#ifndef __OFF_T_MATCHES_OFF64_T
/* build <function> */
#endif
and
<function>64.c
/* build <function>64 */
#ifdef __OFF_T_MATCHES_OFF64_T
weak_alias (fallocate64, fallocate)
#endif
Tested on x86_64, i686, x32, and armhf.
