While auditing all tasklist_lock read_lock sites I stumbled over the
following call chain:audit_prepare_user_tty()
read_lock(&tasklist_lock);
tty_audit_push_task();
mutex_lock(&buf->mutex);--> buf->mutex is locked with preemption disabled.
Solve this by acquiring a reference to the task struct under
rcu_read_lock and call tty_audit_push_task outside of the preempt
disabled region.Move all code which needs to be protected by sighand lock into
tty_audit_push_task() and use lock/unlock_sighand as we do not hold
tasklist_lock.Signed-off-by: Thomas Gleixner

Fix a long standing bug with per device locking.
Each device has an associated spinlock for synchronizing access to
hardware and state information with the ISR. A single hardware card has
one or more devices.Bug: Non ISR code correctly acquires and releases the per device lock.
ISR incorrectly always acquires and releases the lock of the first device
on the card.The decoupled and list based nature of the ISR and deferred processing
interaction allowed this to work in normal operation. Exceptional events
like an application forcing hardware shutdown, reset, or reconfiguration
while active can trigger the bug.Fixed ISR to acquire and release the per device lock.
One exception is manipulation of the GPIO card resource which is global
and effectively owned by the first device of the card. Non-ISR access to
GPIO resource is changed to use lock of first device on card.Signed-off-by: Paul Fulghum

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)

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
