"acpi_wake_gpes_always_on" boot flag for old GPE behaviour

Implemented support for "wake" GPEs via interaction between
GPEs and the _PRW methods.  Every GPE that is pointed to by
one or more _PRWs is identified as a WAKE GPE and by default
will no longer be enabled at runtime.  Previously, we were
blindly enabling all GPEs with a corresponding _Lxx or _Exx
method - but most of these turn out to be WAKE GPEs anyway.
We believe this has been the cause of thousands of
"spurious" GPEs on some systems.

This new GPE behavior is can be reverted to the original
behavior (enable ALL GPEs at runtime) via a runtime flag.

Fixed a problem where aliased control methods could not
access objects properly.  The proper scope within the
namespace was not initialized (transferred to the target of
the aliased method) before executing the target method.

Fixed a potential race condition on internal object
deletion on the return object in AcpiEvaluateObject. 

Integrated a fix for resource descriptors where both
_MEM and _MTP were being extracted instead of just _MEM.
(i.e. bitmask was incorrectly too wide, 0x0F instead of 0x03.)

Added a special case for ACPI_ROOT_OBJECT in AcpiUtGetNodeName,
preventing a fault in some cases.

Updated Notify() values for debug statements in evmisc.c

Return proper status from AcpiUtMutexInitialize,
not just simply AE_OK.

Add "acpi_gsi_to_irq()" as a generic replacement for "acpi_irq_to_vector()".
This converts from an ACPI global system interrupt number to a Linux IRQ.
Also, convert i386-specific terminology to use GSI when appropriate.

When the BIOS enumerates physical processors before logical,
maxcpus=N/2 will now effectively disable HT.

This can be verified by boot messages warning that HT is off:
eg. "maxcpus=2" on a 2xHT system:

Total of 2 processors activated (11141.12 BogoMIPS).
WARNING: No sibling found for CPU 0.
WARNING: No sibling found for CPU 1.

  acpi_osi= will disable the _OSI method -- which by default
	tells the BIOS to behave as if Windows is the OS.
  acpi_serialize is for debugging AE_ALREADY_EXISTS failures

Fixed a problem where errors occurring during the parse phase of control
method execution did not abort cleanly.  For example, objects created
and installed in the namespace were not deleted.  This caused all
subsequent invocations of the method to return the AE_ALREADY_EXISTS
exception.

Implemented a mechanism to force a control method to "Serialized"
execution if the method attempts to create namespace objects.
(The root of the AE_ALREADY_EXISTS problem.)

Implemented support for the predefined _OSI "internal" control method.
Initial supported strings are "Linux", "Windows 2000", "Windows 2001",
and "Windows 2001.1", and can be easily upgraded for new strings as
necessary.  This feature allows Linux to execute
the fully tested, "Windows" code path through the ASL code

Global Lock Support:  Now allows multiple acquires and releases with any
internal thread.  Removed concept of "owning thread" for this special
mutex.

Fixed two functions that were inappropriately declaring large objects on
the CPU stack: ps_parse_loop() and ns_evaluate_relative().
Reduces the stack usage during method execution considerably.

Fixed a problem in the ACPI 2.0 FACS descriptor (actbl2.h) where the
S4Bios_f field was incorrectly defined as UINT32 instead of UINT32_BIT.

Fixed a problem where acpi_ev_gpe_detect() would fault
if there were no GPEs defined on the machine.

Implemented two runtime options:  One to force all control method
execution to "Serialized" to mimic Windows behavior, another to disable
_OSI support if it causes problems on a given machine.

GCC's inability to warn when return values are ignored has conditioned
Linux programmers into thinking that this is actually normal.

This patch fixes the code that workaround lockups when accessing
the config space of devices on K2 when they are shut down. The
code was there but in the wrong place ;) And a typo prevented the
ohci1394 version of it from working.

When adding an additional device, a variable which has been removed
is accessed.  Adding the first device or a 4-port card works.
Adding a second device was not done in PCI hot plug testing.  Now
tested on IA32.

The bug turned out to be memory corruption by DMA, and
the corrupted address made it that much more obvious.

Getting some blood sugar made the real fix for that become
obvious! This replaces the preceding TEMPORARY hack.

Only unlink EDs that aren't already being unlinked!

Duh.

Fix some OHCI TD list corruption issues:

    - Don't rewrite HC registers holding ED pointers until the HC
      had a good chance to finish using them.

    - Don't ever modify ed->hwTailP

Adds text describing the different ED states.

Adds TEMPORARY hack that may make a "rm_list becomes circular" bug
continuable.

This patch was trying to work around buggy SMM bios but causes problems
by not deasserting NMI irq line (reported by Thomas Schlicht) for some
integrated local apic.

This patch was written originally as an optimization (with the side
effect to fix those bugged bios) but was never applied to 2.4 tree.

The rational was: fix your bios instead.

Remember to invalidate the task->tty of threads, otherwise prod_pid_stat()
later stumbles over the dangling pointers and crashes.

The condition still seems to happen on ppc64.

sock_sendmsg() modifies iovec passed to it - it sets all length members of
iovec array to zero on success transmission (and even on failed if it
fails after iovec copy, but...) and advances pointers to point at the end
of buffers used. This has an unfortunate effect that ncpfs's retry on
failure does not work for IPX/UDP connections - kernel refused to do anything
because length from iovec was 0 while length passed to sock_sendmsg() was
correct.

This simple fix gets rid of a problem by creating temporary iovec copy, which can
sock_sendmsg destroy if it has such wish.

This adds infrared remote support for a few more bt878-based TV cards.

From Mike Christie <michaelc@cs.wisc.edu>

The first three bio and request flags are no longer identical.  The bio
barrier and rw flags are getting set in __make_request and get_request
respectively, and failfast is getting left out.

This sets the request's failfast flag in __make_request when the bio's
flag is set.

The ppc64 fix last week (enforcing permissions on the kernel when
accessing userspace pages) uncovered a bug on POWER3/RS64. We werent
zeroing the segment table entry before overwriting it and it was possible
for the ks bit to be set on a kernel segment.

The VSID mask was also changed to match reality (we only use 13 bits).
