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.

x86_64: add new __NR_arch_prctl syscall This is used to set/get TLS on x86_64. There's no public declaration of this because it's not meant to be used outside the C library, like glibc (though we don't currently have any visibility controls to ensure this). Change-Id: I5fc0a5e3ffc3f4cd597d92ee685ab19568ea18f7 Signed-off-by: Pavel Chupin <pavel.v.chupin@intel.com> 2012-12-12 10:18:50 +01:00
Add arch-x86_64/bionic. This is basically half of I5de76f6c46ac87779f207d568a86bb453e2414de from Pavel Chupin <pavel.v.chupin@intel.com>, but with the stock upstream setjump/sigsetjmp and H.J. Lu's suggested changes to __rt_sigreturn. Change-Id: I8167ec228faeb2065391e5bec0413cca662f3d33 2013-10-04 23:55:30 +02:00			`ENTRY(__arch_prctl)`
