Use numbered adapter registration to always have the same hardware bus
show up at the same number.
PWRficient 1682M has three buses, they are all on the same PCI device but
different functions. So do the simple thing and register them based on
function number. Future products, if having a different number of busses,
are expected to have similar behaviour w.r.t. device/function layout.

My guess is that all the chips supported by this driver support block
transactions and reset, but for now we play it safe and only list the
ones for which this was actually tested.

Andi Kleen noticed that we were logging access denied errors (which is
noisy in the dmesg log, and not needed to be logged) and that we were
logging path names on that an other errors (e.g. EIO) which we should
not be doing.

Currently, any new kerberos SMB session overwrites the server's session
key. The session key should only be set by the first SMB session set up
on the socket.

When cifs_mount finds an existing SMB session that it can use for a new
mount, it does not check to see whether that session is in need of being
reconnected. An easy way to reproduce:
1) mount //server/share1
2) watch /proc/fs/cifs/DebugData for the share to go DISCONNECTED
3) mount //server/share2 with same creds as in step 1.
The second mount will fail because CIFSTCon returned -EAGAIN. If you do
an operation in share1 and then reattempt the mount it will work (since
the session is reestablished).
The following patch fixes this by having cifs_mount check the status
of the session when it picks an existing session and calling
cifs_setup_session on it again if it's in need of reconnection.
Thanks to Wojciech Pilorz for the initial bug report.

In ide_taskfile_ioctl(), there was a race condition involving
drive->io_32bit. It was cleared and restored during ioctl
requests but there was no synchronization with other requests.
So, other requests could execute with the altered ->io_32bit
setting or updated drive->io_32bit could be overwritten by
ide_taskfile_ioctl().
This patch adds IDE_TFLAG_IO_16BIT flag to indicate to
ide_pio_datablock() that 16-bit I/O is needed regardless of
drive->io_32bit settting.

Remove broken disk byte-swapping support:
- it can cause a data corruption on SMP (or if using PREEMPT on UP)
- all data coming from disk are byte-swapped by taskfile_*_data() which
results in incorrect identify data being reported by /proc/ide/ and IOCTLs
- "hdx=bswap/byteswap" kernel parameter has been broken on m68k host drivers
(including Atari/Q40 ones) since 2.5.x days (because of 'hwif' zero-ing)
- byte-swapping is limited to PIO transfers (for working with TiVo disks on
x86 machines using user-space solutions or dm-byteswap should result in
much better performance because DMA can be used)
For previous discussions please see:
