(As reported by linux@horizon.com)
Folding is done to minimize the theoretical possibility of systematic
weakness in the particular bits of the SHA1 hash output. The result of
this bug is that 16 out of 80 bits are un-folded. Without a major new
vulnerability being found in SHA1, this is harmless, but still worth
fixing.

Distros seem to be removing PAGE_SIZE from asm/page.h. So, the libc side of
UML should stop using it.
I replace it with UM_KERN_PAGE_SIZE, which is defined to be the same as
PAGE_SIZE on the kernel side of the house. I could also use getpagesize(),
but it's more important that UML have the same value of PAGE_SIZE everywhere.
It's conceivable that it could be built with a larger PAGE_SIZE, and use of
getpagesize() would break that badly.
PAGE_MASK got the same treatment, as it is closely tied to PAGE_SIZE.

Update two points in the SPI interface documentation:
- Update description of the "chip stays selected after message ends"
mode. In some cases it's required for correctness; it isn't just a
performance tweak. (Yes: to use this mode on mult-device busses, another
programming interface will be needed. One draft has been circulated
already.)
- Clarify spi_setup(), highlighting that callers must ensure that no
requests are queued (can't change configuration except between I/Os), and
that the device must be deselected when this returns (which is a key part
of why it's called during device init).

If raid1/repair (which reads all block and fixes any differences it finds)
hits a read error, it doesn't reset the bio for writing before writing
correct data back, so the read error isn't fixed, and the device probably
gets a zero-length write which it might complain about.

The cpuset code to present a list of tasks using a cpuset to user space could
write to an array that it had kmalloc'd, after a kmalloc request of zero size.
The problem was that the code didn't check for writes past the allocated end
of the array until -after- the first write.
This is a race condition that is likely rare -- it would only show up if a
cpuset went from being empty to having a task in it, during the brief time
between the allocation and the first write.
Prior to roughly 2.6.22 kernels, this was also a benign problem, because a
zero kmalloc returned a few usable bytes anyway, and no harm was done with the
bogus write.
With the 2.6.22 kernel changes to make issue a warning if code tries to write
to the location returned from a zero size allocation, this problem is no
longer benign. This cpuset code would occassionally trigger that warning.
The fix is trivial -- check before storing into the array, not after, whether
the array is big enough to hold the store.

It is not safe to use pte_update_defer() in ptep_test_and_clear_young():
its only user, /proc/<pid>/clear_refs, drops pte lock before flushing TLB.
Use the safe though less efficient pte_update() paravirtop in its place.
Likewise in ptep_test_and_clear_dirty(), though that has no current use.
These are macros (header file dependency stops them from becoming inline
functions), so be more liberal with the underscores and parentheses.

Restore tty locked ioctl handler which was replaced with
an unlocked ioctl handler in hung_up_tty_fops by the patch:
commit e10cc1df1d2014f68a4bdcf73f6dd122c4561f94
Author: Paul Fulghum <paulkf@microgate.com>
Date: Thu May 10 22:22:50 2007 -0700
tty: add compat_ioctl
This was reported in:
[Bug 8473] New: Oops: 0010 [1] SMP
The bug is caused by switching to hung_up_tty_fops in do_tty_hangup. An
ioctl call can be waiting on BLK after testing for existence of the locked
ioctl handler in the normal tty fops, but before calling the locked ioctl
handler. If a hangup occurs at that point, the locked ioctl fop is NULL
and an oops occurs.
(akpm: we can remove my debugging code from do_ioctl() now, but it'll be OK to
do that for 2.6.23)

Commit 9b01bd5b284bbf519b726b39f1352023cb5e9e69 introduced a
compat_ioctl handler for RADEON_SETPARAM, the sole purpose of which was
to handle the fact that on i386, alignof(uint64_t)==4.
Unfortunately, this handler was installed for _all_ 64-bit
architectures, instead of only x86_64 and ia64. And thus it breaks
32-bit compatibility on every other arch, where 64-bit integers are
aligned to 8 bytes in 32-bit mode just the same as in 64-bit mode.
Arnd has a cunning plan to use 'compat_u64' with appropriate alignment
attributes according to the 32-bit ABI, but for now let's just make the
compat_radeon_cp_setparam routine entirely disappear on 64-bit machines
whose 32-bit compat support isn't for i386. It would be a no-op with
compat_u64 anyway.

When building with memory hotplug enabled and cpu hotplug disabled, we
end up with the following section mismatch:
WARNING: mm/built-in.o(.text+0x4e58): Section mismatch: reference to
.init.text: (between 'free_area_init_node' and '__build_all_zonelists')
This happens as a result of:
-> free_area_init_node()
-> free_area_init_core()
-> zone_pcp_init() <-- all __meminit up to this point
-> zone_batchsize() <-- marked as __cpuinit fo
This happens because CONFIG_HOTPLUG_CPU=n sets __cpuinit to __init, but
CONFIG_MEMORY_HOTPLUG=y unsets __meminit.
Changing zone_batchsize() to __devinit fixes this.
__devinit is the only thing that is common between CONFIG_HOTPLUG_CPU=y and
CONFIG_MEMORY_HOTPLUG=y. In the long run, perhaps this should be moved to
another section identifier completely. Without this, memory hot-add
of offline nodes (via hotadd_new_pgdat()) will oops if CPU hotplug is
not also enabled.

SCSI marks internal commands with REQ_PREEMPT and push it at the front
of the request queue using blk_execute_rq(). When entering suspended
or frozen state, SCSI devices are quiesced using
scsi_device_quiesce(). In quiesced state, only REQ_PREEMPT requests
are processed. This is how SCSI blocks other requests out while
suspending and resuming. As all internal commands are pushed at the
front of the queue, this usually works.
Unfortunately, this interacts badly with ordered requeueing. To
preserve request order on requeueing (due to busy device, active EH or
other failures), requests are sorted according to ordered sequence on
requeue if IO barrier is in progress.
The following sequence deadlocks.
1. IO barrier sequence issues.
2. Suspend requested. Queue is quiesced with part or all of IO
barrier sequence at the front.
3. During suspending or resuming, SCSI issues internal command which
gets deferred and requeued for some reason. As the command is
issued after the IO barrier in #1, ordered requeueing code puts the
request after IO barrier sequence.
4. The device is ready to process requests again but still is in
quiesced state and the first request of the queue isn't
REQ_PREEMPT, so command processing is deadlocked -
suspending/resuming waits for the issued request to complete while
the request can't be processed till device is put back into
running state by resuming.
This can be fixed by always putting !fs requests at the front when
requeueing.
The following thread reports this deadlock.

Commit 164891aadf1721fca4dce473bb0e0998181537c6 broke RTT
sampling of congestion control modules. Inaccurate timestamps
could be fed to them without providing any way for them to
identify such cases. Previously RTT sampler was called only if
FLAG_RETRANS_DATA_ACKED was not set filtering inaccurate
timestamps nicely. In addition, the new behavior could give an
invalid timestamp (zero) to RTT sampler if only skbs with
TCPCB_RETRANS were ACKed. This solves both problems.

The recent patch that added ipv6_hwtype is broken on tuntap tunnels.
Indeed, it's broken on any device that does not pass the ipv6_hwtype
test.
The reason is that the original test only applies to autoconfiguration,
not IPv6 support. IPv6 support is allowed on any device. In fact,
even with the ipv6_hwtype patch applied you can still add IPv6 addresses
to any interface that doesn't pass thw ipv6_hwtype test provided that
they have a sufficiently large MTU. This is a serious problem because
come deregistration time these devices won't be cleaned up properly.
I've gone back and looked at the rationale for the patch. It appears
that the real problem is that we were creating IPv6 devices even if the
MTU was too small. So here's a patch which fixes that and reverts the
ipv6_hwtype stuff.
Thanks to Kanru Chen for reporting this issue.
