Blackfin: move internal irq prototypes out of global namespace

2011-05-25T12:13:43+00:00

These are only used in a few internal Blackfin places, so move the irq
prototypes out of the global header and into the internal irq one.  No
functional changes other than shuffling locales.

Blackfin: mass clean up of copyright/licensing info

2009-10-07T08:36:26+00:00

Bill Gatliff & David Brownell pointed out we were missing some
copyrights, and licensing terms in some of the files in
./arch/blackfin, so this fixes things, and cleans them up.

It also removes:
 - verbose GPL text(refer to the top level ./COPYING file)
 - file names (you are looking at the file)
 - bug url (it's in the ./MAINTAINERS file)
 - "or later" on GPL-2, when we did not have that right

It also allows some Blackfin-specific assembly files to be under a BSD
like license (for people to use them outside of Linux).

Blackfin: abstract irq14 lowering in do_irq

2009-06-23T01:15:46+00:00

Split out the optional IRQ14 lowering code to further simplify the
asm_do_IRQ() function and keep the ifdef nest under control.

Blackfin: simplify irq stack overflow checking

2009-06-23T01:15:43+00:00

Take a page from x86 and abstract the stack checking out of the
asm_do_IRQ() function so that the result is easier to digest.

Blackfin: redo handling of bad irqs

2009-06-23T01:15:40+00:00

With the common IRQ code initializing much more of the irq_desc state, we
can't blindly initialize it ourselves to the local bad_irq state.  If we
do, we end up wrongly clobbering many fields.  So punt most of the bad irq
code as the common layers will handle the default state, and simply call
handle_bad_irq() directly when the IRQ we are processing is invalid.

Blackfin: fix sparseirq/kstat_irqs fallout

2009-06-12T10:15:36+00:00

The sparseirq changes (d7e51e66) played poorly with the Blackfin irqchip
implementation as we're still using the old hardirq method.  Our bad irq
structure had a NULL kstat_irqs field so when all the common code tries
to increment this field, everything goes big bada boom.
