[PATCH] hwmon: abituguru timeout fixes
This patch contains 2 sets of fixes for the abituguru:
1) Much improved timeout handling, drasticly reducing the amount of
timeout errors on some motherboards
2) Fix the exit paths in the bank1 sensor type detect code to always
restore the original settings even on an error. Without this our
special test settings could remain seriously confusing the system
BIOS's setup menu.
Both are very much related and are must haves, to avoid messing up the
uguru CMOS settings.
Detailed changes:
- Much improved timeout / wait for status handling. Many thanks to Sunil
Kumar, for all his testing, ideas and patches! The code now first busy
waits, polling the uguru for the expected status as this usually
succeeds pretty quickly (within 90 reads). To avoid unnecessary CPU burn
in timeout conditions, the amount of busy waiting has been halved from
previous versions (120 tries instead of 250). This is not a problem,
because this version goes to sleep after 120 attemps for 1 jiffy and
then tries again, it does this sleep and try again 5 times before
finally giving up. This (almost?) completly removes the timeout errors
some people have seen regulary. Apparently some older uguru versions
sometimes are distracted for a (relatively) long time. This solves this.
- These timeout errors not only occur in the sending address part of
reading the uguru but also in the wait for read state, so errors in
this state are now handled as retryable just like send address state
errors and are only logged and reported to userspace if 3 executive
tries fail.
- Fix a very nasty bug in the bank1 sensor type detection code, where it
would not restore the original settings in any of the error paths!
- Since not successfully restoring the original settings can seriously
confuse the system BIOS (hang when entering the relevant setup menu),
we now try restoring them 3 times before giving up.

Alright, this one is only triggered when slab debugging is enabled. The
slabs are assumed to be aligned on a HUGEPTE_TABLE_SIZE boundary. The free
path makes use of this assumption and uses the lowest nibble to pass around
an index into an array of kmem_cache pointers. With slab debugging turned

This would break the assumption above that a full nibble is available for

[PATCH] ppc32: board-specific part of fs_enet update
This contains board-specific portion to respect driver changes (for 8272ads ,
885ads and 866ads). Altered platform_data structures as well as initial setup
routines relevant to fs_enet.
Changes to the mpc8560ads ppc/ code are also introduced, but mainly as
reference, since the entire board support is going to appear in arch/powerpc.

[PATCH] PAL: Support of the fixed PHY
This makes it possible for HW PHY-less boards to utilize PAL goodies. Generic
routines to connect to fixed PHY are provided, as well as ability to specify
software callback that fills up link, speed, etc. information into PHY
descriptor (the latter feature not tested so far).

Unclear how these bugs arrived, presumably from incorrect cleanup of

[PATCH] via-rhine: add option avoid_D3 (work around broken BIOSes)
It looks like broken BIOSes controlling Rhine chips will remain in use in
significant numbers; such systems fail to come up via PXE after they have
been put into D3 (power-saving) mode.
This patch adds a module option for disabling the call that puts the chip
to sleep.

[PATCH] lockdep: fix smc91x
When booting using root-nfs, I'm seeing (independently) two lockdep dumps
in the smc91x driver. The patch below fixes both. Both dumps look like
real locking issues.
Nico - please review and ack if you think the patch is correct.
The poll_enable should be in init_registers before enabling interrupts, not
in tx_timeout. Thanks for spotting it Roger.
