add sigaltstack syscall 2010-02-25 14:27:46 +01:00			`/* autogenerated by gensyscalls.py */`
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			`#include <linux/err.h>`
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			`#include <machine/asm.h>`
The SYS_ constants should cover all __NR_ values. <sys/linux-syscalls.h> only contains constants for the syscalls we're generating stubs for. We want all the syscalls available on the architecture in question. Keep using <sys/linux-syscalls.h> on ARM for now because the __NR_ARM_set_tls and __NR_ARM_cacheflush values aren't in <asm/unistd.h>.
