[PATCH] LOG2: Implement a general integer log2 facility in the kernel

2006-12-08T16:28:51+00:00

This facility provides three entry points:

	ilog2()		Log base 2 of unsigned long
	ilog2_u32()	Log base 2 of u32
	ilog2_u64()	Log base 2 of u64

These facilities can either be used inside functions on dynamic data:

	int do_something(long q)
	{
		...;
		y = ilog2(x)
		...;
	}

Or can be used to statically initialise global variables with constant values:

	unsigned n = ilog2(27);

When performing static initialisation, the compiler will report "error:
initializer element is not constant" if asked to take a log of zero or of
something not reducible to a constant.  They treat negative numbers as
unsigned.

When not dealing with a constant, they fall back to using fls() which permits
them to use arch-specific log calculation instructions - such as BSR on
x86/x86_64 or SCAN on FRV - if available.

[AVR32] Add missing #include to delay.c

[AVR32] Implement intc_get_pending()

2006-12-08T12:08:10+00:00

intc_get_pending() returns a bitmask with pending interrupts in a
interrupt controller group (irq). This is used by the upcoming
oprofile implementation for avr32 and may also be useful for chained
interrupt controller drivers.

[AVR32] Put the chip in "stop" mode when halting the system

2006-12-08T12:06:23+00:00

Make machine_halt() execute a sleep instruction to put the chip in
"stop" mode when the system is halted. This switches off all clocks
except the 32 kHz oscillator, which is needed for the RTC to keep
ticking.

[AVR32] Set flow handler for external interrupts

2006-12-08T12:06:23+00:00

Make sure that the flow handler for external interrupts is updated
whenever they type is changed. Also make sure that the defaults
correspond with how the interrupt controller is configured.
