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 14:27:59 -07:00			`/* 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.

libc: Add ftruncate64 and improve 64-bit parameter syscall handling. This patch improves the handling of 64-bit parameters in syscalls on ARM. The ARM EABI mandates that 64-bit quantities be passed in even/odd register pairs, which requires special treatment. This allows us to simplify our implementations of pread() and pwrite() and remove the C stubs for pread64() and pwrite64(). Also add ftruncate64() to <unistd.h> Change-Id: I407e2fd223ba0093dd2d0b04c6152fadfc9ce3ef Bug 3107933 2010-12-16 16:47:14 +01:00
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 10:47:44 -08:00			`ENTRY(ftruncate64)`
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`
