Merge commit 'v3.7-rc1' into stable/for-linus-3.7
* commit 'v3.7-rc1': (10892 commits)
Linux 3.7-rc1
x86, boot: Explicitly include autoconf.h for hostprogs
perf: Fix UAPI fallout
ARM: config: make sure that platforms are ordered by option string
ARM: config: sort select statements alphanumerically
UAPI: (Scripted) Disintegrate include/linux/byteorder
UAPI: (Scripted) Disintegrate include/linux
UAPI: Unexport linux/blk_types.h
UAPI: Unexport part of linux/ppp-comp.h
perf: Handle new rbtree implementation
procfs: don't need a PATH_MAX allocation to hold a string representation of an int
vfs: embed struct filename inside of names_cache allocation if possible
audit: make audit_inode take struct filename
vfs: make path_openat take a struct filename pointer
vfs: turn do_path_lookup into wrapper around struct filename variant
audit: allow audit code to satisfy getname requests from its names_list
vfs: define struct filename and have getname() return it
btrfs: Fix compilation with user namespace support enabled
userns: Fix posix_acl_file_xattr_userns gid conversion
userns: Properly print bluetooth socket uids
