Use the correct names for the __ARM_NR_* syscalls. This lets us move all the ARM syscall stubs over to the kernel <asm/unistd.h>. Our generated <sys/linux-syscalls.h> is now unused, but I'll remove that in a later change. Change-Id: Ie5ff2cc4abce1938576af7cbaef615a79c7f310d 2013-03-22 21:50:44 +01:00			`#include <asm/unistd.h>`
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>`

Implement clone() C library function properly. Only provide an implementation for ARM at the moment, since it requires specific assembly fragments (the standard syscall stubs cannot be used because the child returns in a different stack). 2010-01-23 03:59:05 +01:00			`mov ip, sp`
