- Subject: Move powerpc64 pread/pwrite definitions to syscalls.list (bug 14138)
- Authentication-results: sourceware.org; auth=none
Concluding the move of syscall definitions to syscalls.list, where the
removal of support for old kernel versions has made this possible,
this patch removes C definitions of pread, pread64, pwrite and
pwrite64 for powerpc64. As far as I can tell, the existing
syscalls.list definitions in
sysdeps/unix/sysv/linux/wordsize-64/syscalls.list should suffice to
produce results equivalent to what these C files do.
Untested; needs powerpc64 testing/review.
