Move pcibios_penalize_isa_irq() to pnpacpi_parse_allocated_irqresource().
Previously we passed the GSI, not the IRQ, and we did it even if parsing
the IRQ resource failed.
Parse IRQ descriptors that contain multiple interrupts. This violates the
spec (in _CRS, only one interrupt per descriptor is allowed), but some
firmware, e.g., HP rx7620 and rx8620 descriptions of HPET, has this bug.

Fixed a problem with the internal Owner ID allocation and
deallocation mechanisms for control method execution and
recursive method invocation. This should eliminate the
OWNER_ID_LIMIT exceptions and "Invalid OwnerId" messages
seen on some systems. Recursive method invocation depth
is currently limited to 255. (Alexey Starikovskiy)

Completely eliminated all vestiges of support for the
"module-level executable code" until this support is
fully implemented and debugged. This should eliminate the
NO_RETURN_VALUE exceptions seen during table load on some
systems that invoke this support.

Fixed a problem within the resource manager code where
the transaction flags for a 64-bit address descriptor were
handled incorrectly in the type-specific flag byte.
Consolidated duplicate code within the address descriptor
resource manager code, reducing overall subsystem code size.

In adjusting the logic for SLB miss for the dynamic hugepage stuff, I
messed up the !CONFIG_HUGETLB_PAGE case, failing to set the SLB flags
properly.
This fixes it. It also streamlines the logic for the HUGETLB_PAGE case
(removing a couple of branches) while we're at it.
Booted, and roughly tested on POWER5 (with and without HUGETLB_PAGE),
iSeries/RS64 (no hugepage available), and G5 (with and without
HUGETLB_PAGE).

Patch from Nicolas Pitre
The prototype for sys_fadvise64_64() is:
long sys_fadvise64_64(int fd, loff_t offset, loff_t len, int advice)
The argument list is therefore as follows on legacy ABI:
fd: type int (r0)
offset: type long long (r1-r2)
len: type long long (r3-sp[0])
advice: type int (sp[4])
With EABI this becomes:
fd: type int (r0)
offset: type long long (r2-r3)
len: type long long (sp[0]-sp[4])
advice: type int (sp[8])
Not only do we have ABI differences here, but the EABI version requires
one additional word on the syscall stack.
To avoid the ABI mismatch and the extra stack space required with EABI
this syscall is now defined with a different argument ordering
on ARM as follows:
long sys_arm_fadvise64_64(int fd, int advice, loff_t offset, loff_t len)
This gives us the following ABI independent argument distribution:
fd: type int (r0)
advice: type int (r1)
offset: type long long (r2-r3)
len: type long long (sp[0]-sp[4])
Now, since the syscall entry code takes care of 5 registers only by
default including the store of r4 to the stack, we need a wrapper to
store r5 to the stack as well. Because that wrapper was missing and was
always required this means that sys_fadvise64_64 never worked on ARM and
therefore we can safely reuse its syscall number for our new
sys_arm_fadvise64_64 interface.

local->hw_priv was initialized only after the interrupt handler was

prism2_pccard_card_present() that assumed that local->hw_priv is always
set (and it should have been). Fix this by setting local->hw_priv before
registering the interrupt handler.
