MIPS: BCM63xx: delete double assignment

2014-08-26T00:18:58Z

Delete successive assignments to the same location. In each case, the duplicated assignment is modified to be in line with other nearby code. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // @@ expression i; @@ *i = ...; i = ...; // Signed-off-by: Julia Lawall Cc: joe@perches.com Cc: kernel-janitors@vger.kernel.org Cc: linux-mips@linux-mips.org Cc: linux-kernel@vger.kernel.org Patchwork: https://patchwork.linux-mips.org/patch/7565/ Signed-off-by: Ralf Baechle

MIPS: BCM63xx: Allow setting affinity for IPIC

2014-07-30T13:30:23Z

Wire up the set_affinity call for the internal PIC if booting on a cpu supporting it. Affinity is kept to boot cpu as default.

MIPS: BCM63xx: Use irq_desc as argument for (un)mask

2014-07-30T13:29:59Z

In preparation for applying affinity, use the irq descriptor as the argument for (un)mask.

MIPS: BCM63xx: Protect irq register accesses

2014-07-30T13:29:23Z

Since we will have the chance of accessing the registers concurrently, protect any accesses through a spinlock.

MIPS: BCM63xx: Append irq line to irq_{stat,mask}*

2014-07-30T13:28:11Z

The SMP capable irq controllers have two interrupt output pins which are controlled through separate registers, so make the variables arrays.

MIPS: BCM63xx: Replace irq dispatch code with a generic version

2014-07-30T13:27:47Z

The generic version uses a variable length of u32 registers instead of u32/u64. This allows easier support for "wider" registers without having to rewrite everything. This "generic" version is as fast as the old version in the best case (i == next set bit), and twice as fast in the worst case in 64 bits. Using a macro was chosen over a (forced) inline version because gcc generated more compact code with the macro. The change from (signed) int to unsigned int for i and to_call was intentional as the value can be only between 0 and (width - 1) anyway, and allowed gcc to optimise the code a bit further.
