Sort the syscalls.mk files, give all generated files the same header. No non-comment changes to the .S files. Change-Id: Iafcfd004c3ea92b64268f80ab16df615b97cefac 2013-10-16 23:27:59 +02:00			`/* Generated by gensyscalls.py. Do not edit. */`

Stop using the non-uapi <linux/err.h> header file. We only need it for MAX_ERRNO, and it's time we had somewhere to put the little assembler utility macros we've been putting off writing.

Regenerate the system call stubs (to get x86_64). This touches the x86 stubs too because arm, x86, and x86_64 now all share the same header (at a source level), which causes a reordering of the #include lines. Change-Id: If9a1e2b2718bd41d8399fea748bce672c513ef84 2013-10-01 22:29:43 +02:00

AArch64: Fix mmap64() definition for AArch64, X86_64 For 64bit Architectures mmap() is equivalent to mmap64(). This patch maps mmap64() to mmap() in a similar way to other syscalls that differ based on the size of off_t and off64_t Change-Id: If21b21ef71120bad23d9a608d02d4a7de5220a87 Signed-off-by: Serban Constantinescu <serban.constantinescu@arm.com> 2013-12-12 10:36:27 +01:00
