commit 9ec26907 ("timerfd: Manage cancelable timers in timerfd")
introduced a CONFIG_HIGHRES_TIMERS (should be CONFIG_HIGH_RES_TIMERS)
typo, which caused applications depending on CLOCK_REALTIME timers to
become sluggy due to the fact that the time base of the realtime
timers was not updated when the wall clock time was set.

This causes anything from 100% CPU use for some applications to odd
delays and hickups.

Most arches define CONFIG_DEBUG_STACK_USAGE exactly the same way.  Move it
to lib/Kconfig.debug so each arch doesn't have to define it.  This
obviously makes the option generic, but that's fine because the config is
already used in generic code.

It's not obvious to me that sysrq-P actually does anything caution by
keeping the most inclusive wording.

DEBUG_PER_CPU_MAPS is used in lib/cpumask.c as well as in

powerpc alone.  Any arch with SMP support may want to get some more
debugging, so make this option generic.

There is quite a lot of code which does copy_from_user() + strict_strto*()
or simple_strto*() combo in slightly different ways.

Before doing conversions all over tree, let's get final API correct.

Enter kstrtoull_from_user() and friends.

Typical code which uses them looks very simple:

	TYPE val;
	int rv;

	rv = kstrtoTYPE_from_user(buf, count, 0, &val);
	if (rv < 0)
		return rv;
	[use val]
	return count;

There is a tiny semantic difference from the plain kstrto*() API -- the
latter allows any amount of leading zeroes, while the former copies data
into buffer on stack and thus allows leading zeroes as long as it fits
into buffer.

This shouldn't be a problem for typical usecase "echo 42 > /proc/x".

The point is to make reading one integer from userspace _very_ simple and
very bug free.

This function makes a deep copy of the platform data to allow it to live
in init memory.  For a kernel that supports several machines and so
includes the definition for several leds-gpio devices this saves quite
some memory because all but one definition can be free'd after boot.

As the function is used by arch code it must be builtin and so cannot go
into leds-gpio.c.

Allow unused leds on pca9532 to be used as gpio.  The board I am working
on now has no less than 6 pca9532 chips.  One chips is used for only leds,
one has 14 leds and 2 gpio and the rest of the chips are gpio only.

There is also one board in mainline which could use this capabilty;
arch/arm/mach-iop32x/n2100.c
 232         {       .type = PCA9532_TYPE_NONE }, /* power OFF gpio */
 233         {       .type = PCA9532_TYPE_NONE }, /* reset gpio */

This patch defines a new pin type, PCA9532_TYPE_GPIO, and registers a
gpiochip if any pin has this type set.  The gpio will registers all chip
pins but will filter on gpio_request.

By setting initial values blink_delay_on and blink_delay_off in a
led_classdev struct, this change starts the blinking when the led is
initialized.

With this patch, you can initialize blink_delay_on and blink_delay_off in
led_classdev with default_trigger set to "timer", and the led will start
up blinking.  The current ledtrig-timer implementation ignores any initial
blink_delay_on/blink_delay_off settings, and requires setting
blink_delay_on/blink_delay_off (typically from userspace) before the led
blinks.

On larger systems, because of the numerous ACPI, Bootmem and EFI messages,
the static log buffer overflows before the larger one specified by the
log_buf_len param is allocated.  Minimize the overflow by allocating the
new log buffer as soon as possible.

On kernels without memblock, a later call to setup_log_buf from
kernel/init.c is the fallback.

On larger systems, information in the kernel log is lost because there is
so much early text printed, that it overflows the static log buffer before
the log_buf_len kernel parameter can be processed, and a bigger log buffer
allocated.

Distros are relunctant to increase memory usage by increasing the size of
the static log buffer, so minimize the problem by allocating the new log
buffer as early as possible.

This patch:

Add an error return if CONFIG_HAVE_MEMBLOCK is not set instead of having
to add #ifdef CONFIG_HAVE_MEMBLOCK around blocks of code calling that
function.

Otherwise, the warning at the top of vsnprintf() gets triggered by
kvasprintf()'s first invocation (with NULL buffer and zero size) of
vsnprintf().

sparse can't parse warning and error attribute.  then they should be
hidden from sparse.

commit c5e631cf ("ARRAY_SIZE: check for type") added __must_be_array().
But sparse can't parse this gcc extention.

Now make C=2 makes following sparse errors a lot.

  kernel/futex.c:2699:25: error: No right hand side of '+'-expression

Because __must_be_array() is used for ARRAY_SIZE() macro and it is
used very widely.

This patch fixes it.

BUILD_BUG_ON() causes a syntax error to detect coding errors.  So it
causes sparse to detect an error too.  This reduces sparse's usefulness.

This patch makes a dummy BUILD_BUG_ON() definition for sparse.
