Disable code doing outb() without any locking in /proc handler.
Otherwise 'cat /proc/ide/hpt366' crashes if done during I/O.

Apparently some IDE drives (e.g. a pile of 80 GB ST380020ACE drives I have
access to) advertise to support LBA48, but don't, causing kernels that support
LBA48 (i.e. anything newer than 2.4.18, including 2.4.25 and 2.6.4) to fail on
them.  Older kernels (including 2.2.20 on the Debian woody CDs) work fine.

Check for id->lba_capacity_2 being non-zero in idedisk_supports_lba48().

The driver was copied from the very-buggy r8169 (pre-Francois),
and is for hardware that isn't even out of the lab yet.

The irq handler must not return 1 when the status register is null
during the firt iteration.

If the pcnet32 interface is not up, running the loopback test may hang or
crash the system.  This patch provided by Jim Lewis fixes that problem.
Tested on ia32 and ppc systems.

Some LOM implementation of our controllers pass IEEE tests (Tx 
distortion/Symmetry) while operating in Class A mode rather than in
class AB mode.

Adding this caused the adapter to fail while operating at 10 mbps, half
duplex. Hence the fix is not complete. We are still investigating a more
complete fix for the polarity reversal issue.

A Bug in e1000_spi_eeprom_ready where the Chip Select bit wasn't being 
toggled after every status register read (if the eeprom wasn't ready after 
the first status register read). The call to e1000_standby_eeprom manages 
the CS bit correctly

We have to restore r13 when entering unrecoverable_exception.

This patch changes PCI_DMA_TODEVICE to DMA_TO_DEVICE in a couple of
places in drivers/net/ibmveth.c, since it doesn't compile without this
change and it does compile with it.  It also reformats a couple of
over-long lines in the vicinity of the other changes.

This is in continuation of the ufs2 read-only code that went into 2.6.5.

This patch fixes a bug where wrong content was being read off the disk

It's been there since the kernel was first imported into bk.  We see no

This patch fixes a problem with the serial conversion to tiocm[sg]et.

The paste from rs_ioctl included the command sanity checking, but there's no
command for tiocm[sg]et.  The compile ends up failing.

drivers/pcmcia/rsrc_mgr.c: In function `find_io_region':
drivers/pcmcia/rsrc_mgr.c:604: warning: large integer implicitly truncated to unsigned type

We don't really know what underlying type an ioaddr_t has, so just use an
integer here and let the compiler promote it appropriately.

Without this one it fails to build, too.

hfs_fill_super in 2.6.5 returns -EIO instead of -EINVAL if a valid supe=
block isn't found.  So mount_block_root in init/do_mounts.c bails out before
trying to mount the root device as XFS.

A few fixes for the 68328 "DragonBall" serial driver:

. use irqreturn_t for interrupt handlers
. correct a few variable types (stop compiler warnings)
. correctly use return values from put_user(), get_user() and copy_to_user()

Many of these originaly from kernel janitors.

A whole bunch of fixes for the ColdFire serial driver:

. remove unused CONFIG_LEDMAN code
. reformat port definitions to new style structure init
. change "addr" field type to reduce casting in ColdFire serial driver
. cleanup locking problems in mcfrs_write().
. implement fraction baud rate clock support for hardware that
  supports it (namely the ColdFire 5272)
. implement wait_until_sent, some ColdFire parts of hardware support
  for this (again the 5272).
. correctly use return values from put_user(), get_user() and copy_to_user()

Many of these originaly from kernel janitors.
