Do not enable this Kconfig menu by default since it contains devices not
present on the majority of systems.This is becoming a pain and a waste of time especially when doing a bunch
of kernel builds on different systems daily and have to answer "make

Our Moorestown platform has two max7315 chips which is covered by pca953x
i2c gpio driver.A while ago this driver got updated with nested irq thread support, and it
broke the compatibity with "request_irq". For example, the gpio_keys.c
driver can not work with this driver now. This patch fixes the issue by
switching to generic_handle_irq.Also fix the irq_base issue: irq_base == 0 is valid, and a "-1" value
should mean invalid. IRQ 0 is not a valid IRQ, irq_base of 0 is valid.Signed-off-by: Alek Du

but does not disable the timer, so the interrupt status bit will still
be set when the timer elapses. If another interrupt arrives before
the timer has been correctly programmed (due to some other device on
the same interrupt line, or CONFIG_DEBUG_SHIRQ), this results in an
extra unwanted interrupt event because the status bit is likely to be
set from comparator matches that happened before the device was opened.Therefore, we have to ensure that the interrupt status bit is and
stays cleared until we actually program the timer.Signed-off-by: Clemens Ladisch

When the initialization code in hpet finds a memory resource and does not
find an IRQ, it does not unmap the memory resource previously mapped.There are buggy BIOSes which report resources exactly like this and what
is worse the memory region bases point to normal RAM. This normally would
not matter since the space is not touched. But when PAT is turned on,
ioremap causes the page to be uncached and sets this bit in page->flags.Then when the page is about to be used by the allocator, it is reported
as:BUG: Bad page state in process md5sum pfn:3ed00
page:ffffea0000dbd800 count:0 mapcount:0 mapping:(null) index:0x0
page flags: 0x20000001000000(uncached)
Pid: 7956, comm: md5sum Not tainted 2.6.34-12-desktop #1
Call Trace:
[] bad_page+0xb1/0x100

[] get_page_from_freelist+0x3a1/0x640
[] __alloc_pages_nodemask+0x10f/0x6b0
...In this particular case:
1) HPET returns 3ed00000 as memory region base, but it is not in
reserved ranges reported by the BIOS (excerpt):
BIOS-e820: 0000000000100000 - 00000000af6cf000 (usable)
BIOS-e820: 00000000af6cf000 - 00000000afdcf000 (reserved)2) there is no IRQ resource reported by HPET method. On the other
hand, the Intel HPET specs (1.0a) says (3.2.5.1):
_CRS (
// Report 1K of memory consumed by this Timer Block
memory range consumed
// Optional: only used if BIOS allocates Interrupts [1]
IRQs consumed
)[1] For case where Timer Block is configured to consume IRQ0/IRQ8 AND
Legacy 8254/Legacy RTC hardware still exists, the device objects
associated with 8254 & RTC devices should not report IRQ0/IRQ8 as
"consumed resources".So in theory we should check whether if it is the case and use those
interrupts instead.Anyway the address reported by the BIOS here is bogus, so non-presence
of IRQ doesn't mean the "optional" part in point 2).Since I got no reply previously, fix this by simply unmapping the space
when IRQ is not found and memory region was mapped previously. It would
be probably more safe to walk the resources again and unmap appropriately
depending on type. But as we now use only ioremap for both 2 memory
resource types, it is not necessarily needed right now.Addresses https://bugzilla.novell.com/show_bug.cgi?id=629908

Keep the current interface but ignore the KM_type and use a stack based
approach.The advantage is that we get rid of crappy code like:
#define __KM_PTE \
(in_nmi() ? KM_NMI_PTE : \
in_irq() ? KM_IRQ_PTE : \
KM_PTE0)and in general can stop worrying about what context we're in and what kmap
slots might be appropriate for that.The downside is that FRV kmap_atomic() gets more expensive.
For now we use a CPP trick suggested by Andrew:
#define kmap_atomic(page, args...) __kmap_atomic(page)
to avoid having to touch all kmap_atomic() users in a single patch.

…structures have been torn down
Under some workloads, some channel messages have been observed being
delayed on the sending side past the point where the receiving side has
been able to tear down its partition structures.This condition is already detected in xpc_handle_activate_IRQ_uv(), but
that information is not given to xpc_handle_activate_mq_msg_uv(). As a
result, xpc_handle_activate_mq_msg_uv() assumes the structures still exist
