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 ...

5 * Partition table and disk geometry handling

7 * A single ioctl with lots of subfunctions:
8 *
9 * Device number stuff:
10 * get_whole_disk() (given the device number of a partition,
11 * find the device number of the encompassing disk)
12 * get_all_partitions() (given the device number of a disk, return the
13 * device numbers of all its known partitions)
14 *
15 * Partition stuff:
16 * add_partition()
17 * delete_partition()
18 * test_partition_in_use() (also for test_disk_in_use)
19 *
20 * Geometry stuff:
21 * get_geometry()
22 * set_geometry()
23 * get_bios_drivedata()
24 *
25 * For today, only the partition stuff - aeb, 990515
