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
Make __set_errno hidden in asm. This fixes the build after the -Bsymbolic change. Bug: 16853291 Change-Id: I989c9fec3c32e0289ea257a3bd2b7fd2709b6ce2 2014-08-09 00:19:20 +02:00			`.hidden __set_errno`

Fix the exit syscall stub's name. I've left the exit_group syscall as _exit because otherwise we'd have to convince the compiler that our _exit (which just calls __exit_group) is actually "noreturn", and it seems like that would be less clean than just cutting out the middleman. We'll just have to trust ourselves not to add anything to SYSCALLS.TXT that ought to be private but that only has a single leading underscore. Hopefully we can manage that.
