h8300, m68knommu, sh and sh64 all used the name asm-offsets.h so minimal
changes required.

Building asm-offsets.h has been moved to a seperate Kbuild file
located in the top-level directory. This allow us to share the
functionality across the architectures.
The old rules in architecture specific Makefiles will die
in subsequent patches.
Furhtermore the usual kbuild dependency tracking is now used
when deciding to rebuild asm-offsets.s. So we no longer risk
to fail a rebuild caused by asm-offsets.c dependencies being touched.
With this common rule-set we now force the same name across
all architectures. Following patches will fix the rest.

When we copy 32bit ->msg_control contents to kernel, we walk the same
userland data twice without sanity checks on the second pass.
Second version of this patch: the original broke with 64-bit arches
running 32-bit-compat-mode executables doing sendmsg() syscalls with
unaligned CMSG data areas
Another thing is that we use kmalloc() to allocate and sock_kfree_s()
to free afterwards; less serious, but also needs fixing.

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.

The 'bus' field in pci_dev structure should be checked before calling
pci_read_config_byte() because pci_bus_read_config_byte() called by
pci_read_config_byte() refers to 'bus' field.

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)
http://bugzilla.kernel.org/show_bug.cgi?id=4892
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.

Implemented a full bytewise compare to determine if a table load
request is attempting to load a duplicate table. The compare is
performed if the table signatures and table lengths match. This
will allow different tables with the same OEM Table ID and
revision to be loaded.
Although the BIOS is technically violating the ACPI spec when
this happens -- it does happen -- so Linux must handle it.

The acpi-cpufreq driver does a P-state get after a P-state set
to verify whether set went through successfully. This test
is kind of redundant as set goes throught most of the times,
and the test is also expensive as a get of P-states can
take a lot of time (same as a set operation) as it goes
through SMM mode. Effectively, we are doubling the P-state
latency due to this get opertion.
momdule parameter "acpi_pstate_strict" restores orginal paranoia.

Andi Kleen suggested it was unconventional for us to "default m"
on ACPI modules -- even though they are expected to be deployed
as modules. But as "default n" would likely result in some
users building nonsense kernels, we compromise to "default y".
Distros are expected to continue to use =m in their configs.

Distros are shipping modules we had marked EXPERIMENTAL,
so clearly it has lost some meaning.
Delete that dependency for shipping modules, retaining
it only for ACPI_HOTKEY and ACPI_CONTAINER to emphasize
that they lack testing on real hardware.

Build issues were mostly in the ACPI=n case -- don't do that.
Select ACPI from IA64_GENERIC.
Add some missing dependencies on ACPI.
Mark BLACKLIST_YEAR and some laptop-only ACPI drivers
as X86-only. Let me know when you get an IA64 Laptop.

There are lots of single-PCI-segment machines that don't
supply _SEG for the root bridges. The PCI root bridge driver
silently assumes the segment to be zero in this case,
so glue.c shouldn't complain either.
