[PATCH] ARM: Acornfb: Don't claim IRQ fbcon for cursor

The generic fbcon code tries to register and use the vsync IRQ for
ARM platforms with acornfb, but forgets to disable its own cursor
timer.  The result is a flickering flashing cursor.

Remove the code from the fbcon core to register this platform
private interrupt.

[PATCH] ARM: Don't try to send a signal to pid0

If we receive an unrecognised abort during boot, don't try to
send a signal to pid0, but instead report the current state.
This leads to less confusing debug reports.

[PATCH] ARM: 2778/1: Add -mno-thumb-interwork to CFLAGS_ABI

Patch from Catalin Marinas

The new EABI gcc adds -mthumb-interwork by default, even if
-mabi=apcs-gnu is passed. This causes a warning for every compiled C
file when -march=armv4 is used. The patch adds -mno-thumb-interwork
if the option is supported. This is also useful since we don't need
any ARM/Thumb interworking in the kernel

If CONFIG_SERIAL_8250_NR_UARTS is smaller than the array size in
asm/serial.h, we trampled on memory which wasn't ours.  Take our
big boots away by limiting the number of ports initialised to the
smaller of ...NR_UARTS and the array size.

[PATCH] alpha smp fix

As usual, the reason of this breakage is quite silly: in do_entIF, we
are checking for PS == 0 to see whether it was a kernel BUG() or
userspace trap.

It works, unless BUG() happens in interrupt - PS is not 0 in kernel mode
due to non-zero IPL, and the things get messed up horribly then.  In
this particular case it was BUG_ON(!irqs_disabled()) triggered in
run_posix_cpu_timers(), so we ended up shooting "current" with the
bursts of one SIGTRAP and three SIGILLs on every timer tick.  ;-)

[PATCH] alpha smp fix (part #2)

This fixes the bug that caused BUG_ON(!irqs_disabled()) to trigger in
run_posix_cpu_timers() on alpha/smp.  We didn't disable interrupts
properly before calling smp_percpu_timer_interrupt().

We *do* disable interrupts everywhere except this unfortunate
smp_percpu_timer_interrupt().  Fixed thus.
