8f91648dcb [PATCH] fixup Documentation/DocBook/kernel-hacking.tmpl
__FUNCTION__ is the prefered kernel idiom, __func__ is not supported by gcc
2.95 (we actually map __FUNCTION__ to __func__ for more recent compilers,
but it should never be used directly)

7e2cff42cf [PATCH] mm: add a note about partially hardcoded VM_* flags
Hugh made me note this line for permission checking in mprotect():

		if ((newflags & ~(newflags >> 4)) & 0xf) {

after figuring out what's that about, I decided it's nasty enough.  Btw
Hugh itself didn't like the 0xf.

We can safely change it to VM_READ|VM_WRITE|VM_EXEC because we never change
VM_SHARED, so no need to check that.

40da47e115 [PATCH] ppc64: Build zImage.vmode for G5
zImage.vmode was recently added.  It's a version of zImage in which the ELF
note section used by open firmware indicates that it requires a virtual
mode instance of OF instead of real mode.  This allows it to work with
Apple OF, and thus is directly bootable (or netbootable) from OF command
line.  (Unfortunately, pSeries OF sort-of requires real mode and Apple OF
sort-of requires virtual mode, and both tend to be unhappy if no notes
section specifies the mode at all).

However, we forgot to add zImage.vmode to the default G5 build. This
fixes it.

3c2822ccb1 [PATCH] PPC64: Fix boot for some pre-POWER4 systems
Some RS64 systems (such as F80) have non-python host bridges with EADS.
However, they have two EADS with 4 buses each under them, so the old logic
that assumed no more than 7 busses per PHB failed miserably.

Big thanks to Olaf Hering for helping me test this, he's got one of the few
machines that broke from the previous logic.

Also, to be a bit smarter at detecting the need for a PHB-level IOMMU table
by checking for the presence of an ISA bus.  Only PHBs with ISA bridges
should need the PHB-level table.

Hence ia64 cannot use printk timestamping, because printk() will crash in

by the architecture via attribute(weak).

a131430c20 [SPARC] cs4231: Fix SBUS support in this driver.
From: Christopher Zimmermann <madroach@zakweb.de>

This patch enables SBus support for the cs4231 sound driver.
It is tested on an Ultra2. Capture and playback both work.
I experienced lags and crashes using certain threaded
players like ogg123 and mp3blaster, while the former is
lagging far more. This behavior may be specific to SMP
systems. It is reproducable using the dummy sound card
driver. Sox works flawlessly.

Setting up the calculation of ptr in snd_cs4231_playback_pointer 
was a bit strange. I got it to work by not incrementing the
[pc]_periods_sent counter when starting DMA the first time
in cs4231_dma_trigger. Therefore this dummy thing.

[ I did some minor cleanups -DaveM ]

0fb375fb9b [AF_PACKET]: Allow for > 8 byte hardware addresses.
The convention is that longer addresses will simply extend
the hardeware address byte arrays at the end of sockaddr_ll and
packet_mreq.

In making this change a small information leak was also closed.
The code only initializes the hardware address bytes that are
used, but all of struct sockaddr_ll was copied to userspace.
Now we just copy sockaddr_ll to the last byte of the hardware
address used.

For error checking larger structures than our internal
maximums continue to be allowed but an error is signaled if we can
not fit the hardware address into our internal structure.

ff171d8f66 [SPARC64]: Handle little-endian unaligned loads/stores correctly.
Because we use byte loads/stores to cons up the value
in and out of registers, we can't expect the ASI endianness
setting to take care of this for us.  So do it by hand.

This case is triggered by drivers/block/aoe/aoecmd.c in the
ataid_complete() function where it goes:

		/* word 100: number lba48 sectors */
		ssize = le64_to_cpup((__le64 *) &id[100<<1]);

This &id[100<<1] address is 4 byte, rather than 8 byte aligned,
thus triggering the unaligned exception.
