Linux 2.5.37

[Linus Torvalds]

Lots of stuff all over the map.  Arch updates (ppc*, sparc*, x86 machine
reorg), VM merges from Andrew, ACPI updates, BIO layer updates,
networking, driverfs, build process, pid hash, you name it it's there.

And that probably still means I missed some stuff.

  o irda update 1-6
  o This is Wireless Extension v15. Mostly enhanced iwpriv support for
    the HostAP driver, with few cleanups and new unused definitions.
    The most contention change is that this version now requires user
    space to provide the buffer size when making a GET (to check buffer
    overrun), which will break very old version of Wireless Tools (v22
    and earlier).
  o A few cleanups for the old ISA wavelen wireless driver
  o Cleanups for the wavelan pcmcia wireless driver
  o This add spinlock protection to the Netwave wireless driver and
    gets rid of save_flags();cli();. I was pleasantly surprised that
    the driver was working fine on my SMP system with those obvious
    fixes. Tested on 2.5.32 SMP.

Jeff Garzik <[e-mail]>:

  o Add support for Cirrus Logic GD7548 chip to clgenfb fbdev driver

    linux-wlan-ng sources and online sources

    Donald Becker)
  o Hey... where did those e100 warnings come from? (kill more e100
    compiler warnings)
  o Update eepro100 net driver's mdio_{read,write} functions to take
    'struct net_device *' not 'long' as their first argument.  This
    makes eepro100 compatible with the standard MII ethtool API,
    preparing it for that support.
  o update eepro100 net driver to use standard MII phy API/lib, when
    implementing ethtool media ioctls.

Linus Torvalds <[e-mail]>:
  o Missing EOL noticed by Chuck Lever
  o Make pid_max grow dynamically as needed
  o If slab debugging is enabled, don't batch slabs on the per-cpu
    lists by default. The batching avoids some debug tests.
  o Remove bogus timer optimization - even if the timer isn't pending,
    it might be actively running on another CPU, so we still need to do
    the synchronous wait.
  o Fix up some merge issues for the Makefle changes in the
    arch-splitup

Manfred Spraul <[e-mail]>:

    devices can be removed from the global list in the process.
  o ACPI: move PREFIX to a common header
  o ACPI: Move sleep code from system.c to sleep.c
  o ACPI: Remove unnecessary objects and code from
    drivers/acpi/system.c
  o ACPI: break procfs handlers for acpi events and debug levels out of
    drivers/acpi/system.c and into their own files
  o ACPI: make CONFIG_ACPI_SLEEP _not_ dependent on
    CONFIG_SOFTWARE_SUSPEND and add help text.
  o ACPI: Remove dead code from drivers/acpi/bus.c
  o ACPI: Remove acpi_exit() and friends, since it's never called
  o ACPI: set acpi_disabled = 1 if acpi_bus_init() fails, and check
    this in the init functions for the other components.
  o ACPI: Move all namespace scanning functions from drivers/acpi/bus.c
    to drivers/acpi/scan.c
  o ACPI: remove the rest of the explicit init function calls and move
    them into the various files and make them initcalls.
  o ACPI: Remove call to acpi_ec_ecdt_probe() in acpi_bus_init() and
    make it a part
  o ACPI: Treat acpi_root_dir as acpi_root_dir when initializing (not
    acpi_device_dir(acpi_root)) (and fix OOPS on boot because acpi_root
    is NULL).
  o ACPI: Move per-componet defines into component files. Only share in
    headers what is needed by multiple users.
  o ACPI: Add call to acpi_ec_ecdt_probe() from acpi_bus_init() again
    and fix the comment to explicitly say that it must be called before
    acpi_initialize_objects().
  o ACPI: Don't use driver model for struct acpi_device; use driverfs
    directly
  o ACPI: move sleep file defines to drivers/acpi/sleep.c (where
    they're used)
  o ACPI: greatly simplify acpi device and acpi driver binding
  o ACPI: lots of minor cleanups in drivers/acpi/scan.c
  o ACPI: don't match every device to every driver
