The current kernel behaviour is to reenable interrupts unconditionally
when taking a page fault. This patch changes this to only enable them
if interrupts were previously enabled.
It also fixes a problem seen with this fix in place: the kernel previously
flushed the vsyscall page when handling a signal, which is not only
unncessary, but caused a possible sleep with interrupts disabled.

avr32: some mmc/sd cleanups
include/video/atmel_lcdc.h must #include <linux/workqueue.h>
avr32: allow system timer to share interrupt to make OProfile work
drivers/misc/atmel-ssc.c: Removed duplicated include
avr32: Add platform data for AC97C platform device
avr32: clean up mci platform code
fix avr32 build errors
Minor cleanups for the MMC/SD support on avr32:
- Make at32_add_device_mci() properly initialize "missing"
platform data ... so boards like STK1002 won't try GPIO 0.
- Switch over to gpio_is_valid() instead of testing for only
one designated value.
- Provide STK1002 platform data for the unlikely case that
switches are set so first Ethernet controller isn't in use.
(That's the only way to get card detect and writeprotect
switch sensing on the STK1000.)
And get rid of one "unused variable" warning.

The lctl(g) instructions require a specific alignment for the parameters.
The architecture requires a specification program check if these alignments
are not used. Enforcing this alignment also removes a possible host BUG,
since the get_guest functions check for proper alignment and emits a BUG.
