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.

Regenerate the system call stubs (to get x86_64). This touches the x86 stubs too because arm, x86, and x86_64 now all share the same header (at a source level), which causes a reordering of the #include lines. Change-Id: If9a1e2b2718bd41d8399fea748bce672c513ef84 2013-10-01 22:29:43 +02:00
Hide statfs/fstatfs' ST_VALID flag from userspace. Spotted while debugging the strace 4.10 upgrade. Change-Id: I1af1be9c9440151f55f74a835e1df71529b0e4fe 2015-03-18 23:46:48 +01:00			`ENTRY(__fstatfs)`

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. (cherry-pick of 7efad83d430f4d824f2aaa75edea5106f6ff8aae.) Bug: 17423135 Change-Id: I6b6d7a05dda85f923d22e5ffd169a91e23499b7b 2014-09-09 00:25:01 +02:00			`call __set_errno_internal`
