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>`
libc: ARM: update syscalls with new script Used the new gensyscalls.py script to update the ARM syscalls with the BEGIN(x) and END(x) macros to give size information for the code of the syscall. Useful for valgrind. Change-Id: I8c481c8928401ac110fd19b087f7d67e4db39326 2011-02-17 19:47:44 +01:00			`#include <machine/asm.h>`

arm syscall : for eabi call_default don't use stack In the default case, we don't need to use the stack, we can save r7 with ip register (that what does eglibc). This allow to fix vfork data corruption (see 3884bfe9661955543ce203c60f9225bbdf33f6bb), because vfork now don't use the stack. 2013-01-16 14:02:50 +01:00			`mov ip, r7`
