A call to va_start() must always be followed by a call to va_end() in the
same function.  In fs/reiserfs/prints.c::print_block() this is not always
the case.  If 'bh' is NULL we'll return without calling va_end().

One could add a call to va_end() before the 'return' statement, but it's
nicer to just move the call to va_start() after the test for 'bh' being
NULL.

The newer drivers/gpio/cs5535-gpio.c replaces drivers/misc/cs5535_gpio.c.
The new driver has been in the tree for a little while, and has received

removal around 2.6.40 would be good, provided we're not missing critical
functionality in the newer driver.

Drop the old geode_gpio crud, as well as the raw outl() calls; instead,
use the Linux GPIO API where possible, and the cs5535_gpio API in other
places.

Note that we don't actually clean up the driver properly yet (once loaded,
it always remains loaded).  That'll come later..

This patch is necessary for building the driver.

This adds (well, re-adds actually) handling for events/IRQs through cs5535
GPIOs.  In the wild and wooly world of CS5535, setup_event() is for
assigning an IRQ to a GPIO filter/event pair, and set_irq() sets up the
pair to trigger IRQs.

These should really only be used in highly platform-specific drivers (such
as OLPC's DCON driver).  Sadly, because set_irq() uses MSRs, this causes
the driver to become X86-specific.

rtc-cmos was setting suspend/resume hooks at the device_driver level.
However, the platform bus code (drivers/base/platform.c) only looks for
resume hooks at the dev_pm_ops level, or within the platform_driver.

Switch rtc_cmos to use dev_pm_ops so that suspend/resume code is executed
again.

It seems there is a small problem of VGA palette corruption on EFI
machine.  When the kernel initializes the architecture, it checks if the
machine is a EFI machine and assumes that a VGA console can exist.

When it initializes the console in vgacon_startup it checks if it can
really use the VGA console.  I think this is where a check is missing.
Currently, the function can fail if a VESA boot mode is detected but not if
a EFI boot mode was used.

Thus vgacon_startup() doesn't fail and initialize the video card for a real
VGA mode.  This function changes the first 16entries of the VGA palette.

When the efifb driver kicks in, the palette is not restored to default
ramp value, thus the 16 first entry remain in a modified state.  The
following patch prevent this corruption.

This cleans up a few bits in binfmt_elf.c and binfmts.h:

- the hasvdso field in struct linux_binfmt is unused, so remove it and
  the only initialization of it

- the elf_map CPP symbol is not defined anywhere in the kernel, so
  remove an unnecessary #ifndef elf_map

- reduce excessive indentation in elf_format's initializer

- add missing spaces, remove extraneous spaces

On some architectures __kernel_suseconds_t is int.  On these archs struct
timeval has padding bytes at the end.  This struct is copied to userspace
with these padding bytes uninitialized.  This leads to leaking of contents
