Rename old vfs_ioctl to do_ioctl, because the comment above it clearly
indicates that it is an internal function not to be exported to modules;
therefore it should have a more traditional do_XXX name. The new do_ioctl
is exported in fs.h but not to modules.
Rename the old do_ioctl to vfs_ioctl because the names vfs_XXX should
preferably be reserved to callable VFS functions which modules may call, as
many other vfs_XXX functions already do. Export the new vfs_ioctl to GPL
modules so others can use it (including Unionfs and eCryptfs). Add DocBook
for new vfs_ioctl.

power: remove POWER_SUPPLY_PROP_CAPACITY_LEVEL
Removed CAPACITY_LEVEL from every other code, leaving the array with sysfs
attributes with one more entry than the number of enums in power_supply.h.
This leads to some attributes containing the value of the attribute right
after it. For example, temp_ambient would have the value of
time_to_empty_now. In my case, I had time_to_full_avg have the value which
should be in model_name, when the former was usually empty.

on a 32-bit kernel, base will overflow when try to do PAGE_SHIFT,
and highest_addr will always less 4G.
So use pfn instead of address to avoid the overflow when more than

This change broke recovery of exceptions in iret:
commit 72fe485854
Author: Glauber de Oliveira Costa <gcosta@redhat.com>
x86: replace privileged instructions with paravirt macros
The ENTRY(native_iret) macro adds alignment padding before the iretq
instruction, so "iret_label" no longer points exactly at the instruction.
It was sloppy to leave the old "iret_label" label behind when replacing
its nearby use. Removing it would have revealed the other use of the
label later in the file, and upon noticing that use, anyone exercising
the minimum of attention to detail expected of anyone touching this
subtle code would realize it needed to change as well.
