The firmware of POWER4 and JS20 systems does not switch the cpu to 64bit
mode when the registered system_reset and machine_check handlers get called.
If a 32bit process runs on that cpu at the time of the event, the cpu
remains in 32bit mode. xmon and kdump can not deal with it, the result is
an error like 'Bad kernel stack pointer fff2aad0 at 3200'.
xmon just loses some register info, but booting the kdump kernel usually fails.
Both handlers are not hot paths. Duplicate the EXCEPTION_PROLOG_PSERIES macro
and add two instructions to switch to 64bit:
li r11,5;
rldimi r10,r11,61,0;

The Xserve G5 are capable of frequency switching like other desktop G5s.
This enables it. It also fix a Kconfig issue which prevented from
building the G5 cpufreq support if CONFIG_PMAC_SMU was not set (the
first version of that driver only worked with SMU based macs, but this
isn't the case anymore).

The thermal control for the Xserve G5s had a few issues. For one, the
way to program the RPM fans speeds into the FCU is different between it
and the desktop models, which I didn't figure out until recently, and it
was missing a control loop for the slots fan, running it too fast. Both
of those problems were causing the machine to be much more noisy than
necessary. This patch also changes the fixed value of the slots fan for
desktop G5s to 40% instead of 50%. It seems to still have a pretty good
airflow that way and is much less noisy.

Rewrite of the bcm43xx initialization routines.
This fixes several issues:
* up-down-up-down-up... stale data issue
(May fix some DHCP issues)
* Fix the init vs IRQ handler race (and remove the workaround)
* Fix init for cards with multiple cores (APHY)
As softmac has no internal PHY handling (unlike dscape),
this adds the file "phymode" to sysfs.
The active PHY can be selected by writing either a, b or g
to this file. Current PHY can be determined by reading from it.
* Fix the controller restart code.
Controller restart can now also be triggered through
echo 1 > /debug/bcm43xx/ethX/restart

ieee80211_rx_any is new to 2.6.18-rc1, even though it appears this function
was never completed:
http://lists.sipsolutions.net/pipermail/softmac-dev/2006-February/000103.html
This patch changes ieee80211_rx_any to always claim the skb, which avoids
further driver complexity and the possibility of leaking management frames.
It also exports the function so that people can actually use it.

This patch implements ERP handling in softmac so that the drivers can support
protection and preambles properly.
I added a new struct, ieee80211softmac_bss_info, which is used for
BSS-dependent variables like these.
A new hook has been added (bssinfo_change), which allows the drivers to be
notified when anything in bssinfo changes.
I modified the txrates_change API to match the bssinfo_change API. The
existing one is a little messy and the usefulness of providing the old rates
is questionable (and can be implemented at driver level if really necessary).
No drivers are using this API (yet), so this should be safe.

This adds a flag to the ieee80211_network structure which indicates whether
the stored erp_value is valid (a check against 0 is not enough, since an ERP
of 0 is valid and very meaningful).
I also added the ERP IE bit-definitions to ieee80211.h.
This is needed by some upcoming softmac patches.

Johann Uhrmann reported a bcm43xx crash and Michael Buesch tracked
it down to a problem with the new shared key auth code (recursive
calls into the driver)
This patch (effectively Michael's patch with a couple of small
modifications) solves the problem by sending the authentication
challenge response frame from a workqueue entry.
I also removed a lone \n from the bcm43xx messages relating to
authentication mode - this small change was previously discussed but
not patched in.

instruction with a busy indication (cc 2), I/O may stall.
I/O request termination logic retries HALT I/O indefinitely
because it expects HALT I/O to alter the subchannel status which
is not true when cc 2 is returned.
