The acpi cpufreq driver includes a test at startup which detects whether
ACPI P-States are supported on any CPU, and whether transitions work.
However, this test is faulty: it is only run _after_ the acpi driver is
registered, causing race situations. Also, it doesn't save anything _as_ the
driver is already registered. So, it can safely be removed.

The current algorithm used by Linux ACPI for passive thermal management has
two shortcomings:

- if increasing the CPU processing power as a thermal situation goes away,
  throttling states are decreased later than performance states. This is
  not wise -- it should be the opposite ordering of going "up".

- only if the ACPI CPUfreq driver is used, performance states are used.
  A generalized approach would offer passive cooling even if the ACPI
  P-States cpufreq driver cannot be used (faulty BIOS, FixedHW access, etc.)

The purpose of this release is primarily to update the copyright years
in each module, thus causing a huge number of diffs.  There are a few
small functional changes, however.

Improved error messages when there is a problem finding one or more of
the required base ACPI tables

Reintroduced the definition of APIC_HEADER in actbl.h

Changed definition of MADT_ADDRESS_OVERRIDE to 64 bits (actbl.h)

Removed extraneous reference to NewObj in dsmthdat.c

This fixes a bug in the qla1280 driver where it would leave a pointer to
an on the stack completion event in a command structure if
qla1280_mailbox_command fails.  The result is that the interrupt handler
later tries to complete() garbage on the stack.  The mailbox command can
fail if a device on the bus decides to lock up etc.

I just found Yet Another Bug in scsi_ioctl - CDROM_SEND_PACKET puts a
kernel pointer in hdr->cmdp, where sg_io() expects to find user address.
This worked up until recently because of the memcpy bug, but now it
doesn't because we do the proper copy_from_user(). 

This fix undoes the user copy code from sg_io, and instead makes the
SG_IO ioctl copy it locally.  This makes SG_IO and CDROM_SEND_PACKET
agree on the calling convention, and everybody is happy. 

I've tested that both

   cdrecord -dev=/dev/hdc -inq

and

   cdrecord -dev=ATAPI:/dev/hdc -inq

works now.  The former will use SG_IO, the latter CDROM_SEND_PACKET (and
incidentally would work in both 2.4 and 2.6, if it wasn't for
CDROM_SEND_PACKET sucking badly in 2.4).

From Jon Burgess:

  There is a problems with blank DVD media using the ide-cd driver.

  When we attempt to read the blank disk, the drive responds to the read
  request by returning a "blank media" error.  The kernel doesn't have
  any special case handling for this sense value and retries the request
  a couple of times, then gives up and does a bus reset and disables DMA
  to the device.

  Which obviously doesn't help the situation.

  The sense key value of 8 isn't listed in ide-cd.h, but it is listed in
  scsi.h as a "BLANK_CHECK" error.

  This trivial patch treats this error condition as a reason to abort
  the request.  This behaviour is the same as what we do with a blank CD-R.

  It looks like the same fix might be desired for 2.4 as well, although
  is perhaps not so important since scsi-ide is normally used instead.

The current approach is to walk the _CRS in pcibios_scan_root()
using acpi_walk_resources().

 1/ make sure raid5 doesn't try to handle multiple overlaping
    requests at the same time as this would confuse things badly.
    Currently it justs BUGs if this is attempted.
 2/ Fix a possible data-loss-on-write problem.  If two or
    more bio's that write to the same page are processed at the
    same time, only the first was actually commited to storage.
 3/ Fix a use-after-free bug.  raid5 keeps the bio's it is given
    in linked lists when more than one bio touch a single page.
    In some cases the tail of this list can be freed, and
    the current test for 'are we at the end' isn't reliable.
    This patch strengths the test to make it reliable.

Petr Vandrovec noticed a problem where the thread group leader
would not be properly reaped if the parent of the thread group
was ignoring SIGCHLD, and the thread group leader had exited
before the last sub-thread.

Fixed by Ingo Molnar.

This time we have a SMP memory ordering issue in prepare_to_wait(),
where we really need to make sure that subsequent tests for the
event we are waiting for can not migrate up to before the wait
queue has been set up.

In 2.5.x, the BKL was pushed from vfs_readdir() into the filesystem
specific functions.  But only the unlock_kernel() made it into the HPFS
code, lock_kernel() got lost on the way.  This rendered the filesystem
unusable.

This adds the missing lock_kernel().  It's been tested by Timo Maier who
also reported the problem earlier today.

The previous scsi_ioctl.c patch didn't cleanup the buffer/bio in the
error case. 

Fix it by copying the command data earlier.

corruption on SMP because of another CPU still accessing a waitqueue
even after it was de-allocated.

Use a careful version of the list emptiness check to make sure we
don't de-allocate the stack frame before the waitqueue is all done.

Changed the initialization of Operation Regions during subsystem init to
perform two entire walks of the ACPI namespace; The first to initialize
the regions themselves, the second to execute the _REG methods.  This
fixed some interdependencies across _REG methods found on some machines.

Fixed a problem where a Store(Local0, Local1) could simply update the
object reference count, and not create a new copy of the object if the
Local1 is uninitialized.

Implemented support for the _SST reserved method during sleep
transitions.

Implemented support to clear the SLP_TYP and SLP_EN bits when waking up,
this is apparently required by some machines.

When sleeping, clear the wake status only if SleepState is not S5.

Fixed a problem in AcpiRsExtendedIrqResource() where an incorrect
pointer arithmetic advanced a string pointer too far.

Fixed a problem in AcpiTbGetTablePtr() where a garbage pointer could be
returned if the requested table has not been loaded.

Within the support for IRQ resources, restructured the handling of the
active and edge/level bits.

Fixed a few problems in AcpiPsxExecute() where memory could be leaked
under certain error conditions.

Improved error messages for the cases where the ACPI mode could not be
entered.

Fixed a problem where a level-triggered GPE with an associated _Lxx
control method was incorrectly cleared twice.

Fixed a problem with the Field support code where an access can occur
beyond the end-of-region if the field is non-aligned but extends to the
very end of the parent region (resulted in an AE_AML_REGION_LIMIT
exception.)

Fixed a problem with ACPI Fixed Events where an RT Clock handler would
not get invoked on an RTC event.  The RTC event bitmasks for the PM1
registers were not being initialized properly.

Implemented support for executing _STA and _INI methods for Processor
objects.  Although this is currently not part of the ACPI specification,
there is existing ASL code that depends on the init-time execution of
these methods.

Implemented and deployed a GetDescriptorName function to decode the
various types of internal descriptors.  Guards against null descriptors
during debug output also.

Implemented and deployed a GetNodeName function to extract the
4-character namespace node name.  This function simplifies the debug and
error output, as well as guarding against null pointers during output.

Implemented and deployed the ACPI_FORMAT_UINT64 helper macro to simplify
the debug and error output of 64-bit integers.  This macro replaces the
HIDWORD and LODWORD macros for dumping these integers.

Updated the implementation of the Stall() operator to only call
AcpiOsStall(), and also return an error if the operand is larger than
255.  This preserves the required behavior of not relinquishing the
processor, as would happen if AcpiOsSleep() was called for "long
stalls".

Constructs of the form "Store(LocalX,LocalX)" where LocalX is not
initialized are now treated as NOOPs.

Cleaned up a handful of warnings during 64-bit generation.

Fixed a reported error where and incorrect GPE number was passed to the
GPE dispatch handler.  This value is only used for error output,
however.  Used this opportunity to clean up and streamline the GPE
dispatch code.

visor.c defines one empty slot in USB ids table that can be filled in at
runtime using module parameters. file2alias generates catch-all alias for it:

alias usb:v*p*dl*dh*dc*dsc*dp*ic*isc*ip* visor

patch adds the same sanity check as in depmod to scripts/file2alias.

This patch fixes the bug where running ppp over a ttyUSB device would fail.

This patch was integrated by you in 2.4 six months ago.  Unfortunately
it never got into 2.5.  Without it you can end up with crashes such
as http://bugs.debian.org/218670

apart from locking bugs, there are other races. This fixes one with
signal delivery. The signal should be delivered _before_ the reciever
is woken.
