alpha, gpio: GENERIC_GPIO default must be n

2011-09-15T01:09:37+00:00

Since GPIOLIB is optional on alpha, GENERIC_GPIO must not be selected by
default.  If GPIOLIB is enabled, it will select GENERIC_GPIO.

See  for an example of what 'def_bool y'
breaks.

Add Kconfig option ARCH_HAVE_NMI_SAFE_CMPXCHG

2011-08-03T15:12:37+00:00

cmpxchg() is widely used by lockless code, including NMI-safe lockless
code.  But on some architectures, the cmpxchg() implementation is not
NMI-safe, on these architectures the lockless code may need a
spin_trylock_irqsave() based implementation.

This patch adds a Kconfig option: ARCH_HAVE_NMI_SAFE_CMPXCHG, so that
NMI-safe lockless code can depend on it or provide different
implementation according to it.

On many architectures, cmpxchg is only NMI-safe for several specific
operand sizes. So, ARCH_HAVE_NMI_SAFE_CMPXCHG define in this patch
only guarantees cmpxchg is NMI-safe for sizeof(unsigned long).

pcspkr: Cleanup Kconfig dependencies

2011-06-09T13:01:41+00:00

Lenghty lists of the kind "depends on ARCH1 || ARCH2 ... || ARCH123" are
usually either wrong or too coarse grained.  Or plain an ugly sin.

arch: remove CONFIG_GENERIC_FIND_{NEXT_BIT,BIT_LE,LAST_BIT}

2011-05-27T00:12:38+00:00

By the previous style change, CONFIG_GENERIC_FIND_NEXT_BIT,
CONFIG_GENERIC_FIND_BIT_LE, and CONFIG_GENERIC_FIND_LAST_BIT are not used
to test for existence of find bitops anymore.

alpha: hook up gpiolib support

2011-05-25T15:39:38+00:00

Allow people to use gpiolib on Alpha if they want to, mostly for build
coverage.  The header is a stright copy of that for Microblaze, which in
turn was taken from PowerPC.

alpha: Use generic show_interrupts()

2011-03-29T12:47:58+00:00

The only subtle difference is that alpha uses ACTUAL_NR_IRQS and
prints the IRQF_DISABLED flag.

Change the generic implementation to deal with ACTUAL_NR_IRQS if
defined.

The IRQF_DISABLED printing is pointless, as we nowadays run all
interrupts with irqs disabled.
