[PATCH] fix ppc32 sys_swapcontext
This fixes a bug in the swapcontext system call on ppc32.
On ppc32, the system call entry only saves the volatile registers,
except in the case of a few system calls (e.g. fork) which need all the
registers saved. Swapcontext needs all the registers but we weren't
saving them all. So fixes that.

[PATCH] Threaded core dumps for PPC32
At the moment, ppc32 kernels will oops if a threaded program tries to
dump core. We call dump_fpu with a NULL regs pointer, which it tries
to dereference.
This fixes the issue by implementing the hooks used in doing threaded
core dumps properly.
In the long story of "BenH can't get a simple fix right the first time",
please add this one to pmac_zilog, and now people should enjoy really
working sleep again on pmac laptops ...
If the serial port was closed, we could use an uninitialized "pwr_delay"
and pass that to schedule_timeout().

[PATCH] fbcon font cloning fix
From: Petr Baudis <pasky@ucw.cz>
This patch fixes a bug which I hit when migrating from 2.4. Basically,
when I do setfont during the system boot, the then-spawned ttys do not
retain the new font but fall back to the default one.
I've tracked that down to a clearly bogus test in fbcon_set_display(),
because vc->vc_font.width is not set at that time yet (no font has been
loaded for the new vc). But even if it would (or this was meant to test
against tmp->vc_font.width), it would mean only *HUGE* fonts would be
retained. And even if there were *two* bugs there and it was supposed to
be less-than there, I couldn't make a sense of the test.

[CRYPTO]: Add Michael MIC algorithm.
From Jouni Malinen <jkmaline@cc.hut.fi>
Added Michael MIC keyed digest for TKIP (IEEE 802.11i/WPA). This algorithm
is quite weak due to the requirements for compatibility with old legacy
wireless LAN hardware that does not have much CPU power. Consequently, this
should not really be used with anything else than TKIP.
Michael MIC is calculated over the payload of the IEEE 802.11 header which
makes it easier to add TKIP support for old wireless LAN cards. An additional
authenticated data area is used (but not send separately) to authenticate
source and destination addresses.

[PATCH] Revert UDF inode semaphore locking
For some reason I don't understand, the last UDF filesystem update makes
the UDF deadlock when I write a bunch of mp3 files to a CDRW using the
packet writing patch. Both "cp" and pdflush get stuck in __down.
Reverting the semaphore changes makes the problem go away. Use the
kernel lock again, until whatever recursive offender gets fixed.
(The offensive recursion seems to be: write() takes the inode semaphore,
causes memory pressure, and then trying to write back the inode or dirty
data to disk tries to get the semaphore again and deadlocks.)

In the i386 case we need to generate asm-offset.h, before starting building

that allows us to do: make some/dir/file.s

not see this problem on i386. But David hit it with sparc64, because there
is no asm-offset.h file. No parallel stuff involved here, just an ordinary
