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.

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.

Ensure __set_errno is still visible on LP32. The use of the .hidden directive to avoid going via the PLT for __set_errno had the side-effect of actually making __set_errno hidden (which is odd because assembler directives don't usually affect symbols defined in a different file --- you can't even create a weak reference to a symbol that's defined in a different file). This change switches the system call stubs over to a new always-hidden __set_errno_internal and has a visible __set_errno on LP32 just for binary compatibility with old NDK apps.
