irqchip: sirf: move from legacy mode to linear irqdomain

2013-08-29T16:48:32+00:00

the series of patches for irqdomain core in 3.11 has broken sirf
irq which uses legacy mapping. all users fail in the new kernel
while setupping irq.

this patch moves to linear irqdomain and drop old legacy irqdomain
codes since we don't need it any more, and at the same time, it
also fixes the broken interrupts of sirfsoc in 3.11.

on the other hand, we actually only have 64 interrupt sources for
prima2 and atlas6, but there are 128 interrupt souces for marco
which uses GIC. in the legacy codes, sirf gpio also uses legacy
irqdomain, so to make gpio interrupt mapping not depend on the
prima2/atlas6/marco an use unified marco,we enlarge prima2/atlas6
interrupt number to 128. here we don't need this workaround any
more as sirf gpio also moved to linear mode before. so we move
SIRFSOC_NUM_IRQS back to 64 too.

clocksource+irqchip: delete __cpuinit usage from all related files

2013-07-14T23:36:57+00:00

The __cpuinit type of throwaway sections might have made sense
some time ago when RAM was more constrained, but now the savings
do not offset the cost and complications.  For example, the fix in
commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time")
is a good example of the nasty type of bugs that can be created
with improper use of the various __init prefixes.

After a discussion on LKML[1] it was decided that cpuinit should go
the way of devinit and be phased out.  Once all the users are gone,
we can then finally remove the macros themselves from linux/init.h.

This removes all the drivers/clocksource and drivers/irqchip uses of
the __cpuinit macros from all C files.

The third parameter of irq_alloc_domain_generic_chips() is the number of
irq_chip_type instances associated with these chips rather than numbanks.

 "These changes from 30 individual branches for the most part update
  device tree files, but there are also a few source code changes that
  have crept in this time, usually in order to atomically move over a

  A number of platforms change their DT files to use the C preprocessor,
  which is causing a bit of churn, but that is hopefully only this once"
