alpha: fix breakage caused by df9ee29270

2011-01-17T04:42:15+00:00

Commit df9ee29270 made arch_local_irq_save and arch_local_irq_restore
static inline which with -Werror trips up on __set_hae() and _set_hae()
which are extern inline.  The naive solution is to make __set_hae() and
set_hae() static inline but for reasons described in commit d559d4a24a3fe
this breaks the generic kernel build.  Instead, since this is architecture
specific code, this patch hard wires in the architecture specific method
f disabling and enabling interrupts.

alpha: kill off alpha_do_IRQ

2011-01-17T04:42:13+00:00

Good riddance... Nuke a pile of redundant handlers that the
generic code takes care of as well.

alpha: use set_irq_chip and push down __do_IRQ to the machine types

2011-01-17T04:42:11+00:00

Also kill superfluous IRQ_DISABLED initialization, since that's the
default state of the irq_desc[i].status field.

perf, arch: Cleanup perf-pmu init vs lockup-detector

2010-11-26T14:14:56+00:00

The perf hardware pmu got initialized at various points in the boot,
some before early_initcall() some after (notably arch_initcall).

The problem is that the NMI lockup detector is ran from early_initcall()
and expects the hardware pmu to be present.

Sanitize this by moving all architecture hardware pmu implementations to
initialize at early_initcall() and move the lockup detector to an explicit
initcall right after that.

alpha: use single HAE window on T2 core logic (gamma, sable)

2010-10-26T23:52:12+00:00

T2 are the only alpha SMP systems that do HAE switching at runtime, which
is fundamentally racy on SMP.  This patch limits MMIO space on T2 to HAE0
only, like we did on MCPCIA (rawhide) long ago.  This leaves us with only
112 Mb of PCI MMIO (128 Mb HAE aperture minus 16 Mb reserved for EISA),
but since linux PCI allocations are reasonably tight, it should be enough
for sane hardware configurations.

Also, fix a typo in MCPCIA_FROB_MMIO macro which shouldn't call set_hae()
if MCPCIA_ONE_HAE_WINDOW is defined.  It's more for correctness, as
set_hae() is a no-op anyway in that case.

mm: remove pte_*map_nested()

2010-10-26T23:52:08+00:00

Since we no longer need to provide KM_type, the whole pte_*map_nested()
API is now redundant, remove it.
