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.

The DS1WM driver incorrectly infers the IAS bit (1-wire interrupt active
high) from IRQ settings. There are devices that have IAS=0 but still need
the IRQ to trigger on a rising edge. With this patch, machines with DS1WM
that need IAS=1 have to set .active_high=1 in the ds1wm_platform_data.

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.

The early per-cpu handling needs a slight tweak to work when booting
on a non-zero cpu.
We got away with this for a long time, but can't any longer as now
even printk() calls functions (cpu_clock() for example) that thus make
early references to per-cpu variables.

MTDs are well suited for logging critical data and the mtdoops driver
allows kernel panics/oops to be written to flash in a blackbox flight
recorder fashion allowing better debugging and analysis of crashes.
Any kernel oops in user context can be easily handled since the kernel
continues as normal and any queued mtd writes are scheduled. Any kernel
oops in interrupt context results in a panic and the delayed writes will
not be scheduled however. The existing mtd->write function cannot be
called in interrupt context so these messages can never be written to
flash.
This patch adds a panic_write function pointer that drivers can
optionally implement which can be called in interrupt context. It is
only intended to be called when its known the kernel is about to panic
and we need to write to succeed. Since the kernel is not going to be
running for much longer, this function can break locks and delay to
ensure the write succeeds (but not sleep).

This makes the SPE register data appear in ELF core dumps, using the
new n_type value NT_PPC_SPE (0x101). This new note type is not used
by any consumers of core files yet, but support can be added. I don't
even have any hardware with SPE capabilities, so I've never seen such
a note. But this demonstrates how simple it is to export register
information in core dumps when the user_regset style is used for the
low-level code.
