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.

Switch x86 syscall stubs over to the ENTER/END style of the ARM stubs. Also update the x86 asm.h to support this; we need it for libm assembler anyway. Also clean up the _FBSDID hack in <sys/cdefs.h>. Change-Id: Iababd977b8110ec022bf7c93f4d62ece47630e7c 2013-02-07 02:08:15 +01:00			`ENTRY(__brk)`

Use the kernel's MAX_ERRNO in the syscall stubs. Bug: http://code.google.com/p/android/issues/detail?id=53104 Change-Id: Iaabf7025b153e96dc5eca231a33a32d4cb7d8116 2013-03-12 22:57:30 +01:00			`cmpl $-MAX_ERRNO, %eax`
