Merge tag 'cpumask-next-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux

2015-04-20T17:19:03+00:00

Pull final removal of deprecated cpus_* cpumask functions from Rusty Russell:
 "This is the final removal (after several years!) of the obsolete
  cpus_* functions, prompted by their mis-use in staging.

  With these function removed, all cpu functions should only iterate to
  nr_cpu_ids, so we finally only allocate that many bits when cpumasks
  are allocated offstack"

MIPS: BCM63xx: Move bcm63xx_gpio_init() to bcm63xx_register_devices().

2015-03-25T12:47:55+00:00

When called from prom init code, bcm63xx_gpio_init() will fail as it
will call gpiochip_add() which relies on a working kmalloc() to alloc
the gpio_desc array and kmalloc is not useable yet at prom init time.

Move bcm63xx_gpio_init() to bcm63xx_register_devices() (an
arch_initcall) where kmalloc works.

Fixes: 14e85c0e69d5 ("gpio: remove gpio_descs global array")

mips: fix up obsolete cpu function usage.

2015-03-05T04:55:06+00:00

Thanks to spatch, plus manual removal of "&*".  Then a sweep for
for_each_cpu_mask => for_each_cpu.

MIPS: BCM63xx: delete double assignment

2014-08-26T00:18:58+00:00

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/)

//

MIPS: BCM63xx: Allow setting affinity for IPIC

2014-07-30T13:30:23+00:00

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.

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