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.

add sigaltstack syscall 2010-02-25 14:27:46 +01:00
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(sigaltstack)`

Add cfi directives to x86 syscalls. Modify the syscalls script to generate the cfi directives for x86 syscalls. Update the x86 syscalls. Change-Id: Ia1993dc714a7e79f917087fff8200e9a02c52603 2014-01-07 01:39:10 +01:00			`.cfi_def_cfa_offset 8`

Fix x86 cfi directives for syscalls. The syscall generation always used 4 bytes for each push cfi directive. However, the first push should always use an offset of 8 bytes, each subsequent push after that is only 4 bytes though.
