[LLC]: when the user doesn't specifies a local address to connect, do an autobind
Other protocols do this as soon as they discover over what interface the
packet will be routed, but LLC isn't routable, so, to provide similar
semantics to the other protocols, I'm just binding it to the first interface
of the type specified, perhaps we'll need a tunable for this or some sort of
routing table done manually by the admin, later we'll see, for now this
allows an application like openssh, with patched getaddrinfo/getnameinfo to
use PF_LLC sockets with a very small patch.

Here is the minimal patch that fixes things that do not work and that
can be noticed fairly easily:
- remove a typo in pfm_check_task_state() which causes
PFM_READ_PMDS to fail when context is in PFM_MASKED state.
- fix a typo in perfmon_mcklinley.h when checking the value
combinations for when writing to PMC14. This could reject a
valid request to program PMC14.

[PATCH] Essential x86-64 updates
The most important part is that it makes x86-64 compile again.
Without that 2.6 users won't be very happy.
It also works around a bug that allowed every user program to reboot the
system on B stepping K8.
Also update to match some recent i386 fixes.
Full ChangeLog:
- Add acpi_pic_set_level_irq to make ACPI compile again
- Work around compat mode K8 bug in IRET exception handling
- Increase exception stack. The old 1k stack was too easy
to overflow (from Jim Paradis, changed by me)
- Replace safe_smp_processor_id with cpuid (needed for above)
- When there is only one node always enable fake_node mode
- Merge with i386 (NTP gettimeofday monoticity fix, irq nr_vectors change)
- Fix compile problem for UP kernels in time/cpufreq
- Set all nodes online at bootup
- Define node_to_cpumask correctly
The first FAT entry should have the media byte (0xf0,0xf8,...,0xff)
extended with all 1 bits in the first FAT entry.
Checking this is a good idea, it prevents us from mounting garbage
as FAT - there is no good magic for FAT.
Unfortunately, Windows does not enforce this, and 2.4 doesn't either.
It turns out that there are filesystems around (two reports so far) that
have a zero first FAT entry, and work under Windows and 2.4 but fail to
mount under 2.6.
The 0xfa code can be a key scancode or it can be a protocol scancode.
Only few keyboards use it as a key scancode, and if we always interpret
it as a protocol scancode then these rare keyboards will have a dead
key. If we interpret it as a key scancode then we have a dead keyboard
in case it was protocol.
Clearly it is safer to prefer to interpret it as a protocol scancode.
This moves the test for ACK and NAK up, so that they are always seen as
protocol.
This is just a minimal patch. What I did in 1.1.54 was to keep track of
commands sent with a flag reply_expected, so that 0xfa could be taken as
ACK when a reply is expected and as key scancode otherwise. That is the
better solution, but requires larger surgery.

[PATCH] setkeycode ioctl fix
This is a bugfix for setkeycode() in /drivers/char/keyboard.c.
If we change a keycode the corresponding bit should be cleared if and
only if this keycode is not defined any longer. I believe that this
also was intended with the original code, but the implementation is
faulty.
First off all the first three changed lines are obviously erroneus:
oldkey == truekey is false or true, you do not need to inclose this in a
for(). I believe the author intended INPUT_KEYCODE(dev,i) == oldkey.
But fixing this alone is not enough.
If somebody wants to interchange the definition of two keys A and B, the
normal way is to use two setkeycode calls:
setkeycode (scancode A, keycode B);
setkeycode (scancode B, keycode A);
The old code does a clearbit(oldkey ..) call even in situations where
two keys have the same definition, and this situation arises commonly in
the situation mentioned above.

[PATCH] input / keyboard / Scancode Set 3 support broken
If somebody uses keyboard scancode set 3 it is necessary to explicitly
program the keyboard to send make/break codes for all keys and to set
autorepeat for all keys.
This is critical for some people. One example is the LK461/46W series
of keyboards from Digital Equipment Corporations. These are VMS
keyboards that are also usable on a normal PC.
These keyboards support Scancode Set 2, but for some keys this support
is screwed up -- some function keys (e.g. F18/F20) report the same
scancode sequence combined with both alt and shift keys.
Scancode Set 3 works perfectly if all keys are programmed to give
make/break codes.
A lot of keyboards manufactured by Cherry only make/break for some (not all!)
modifyer keys in scancode set 3 without this fix.

[PATCH] USB: usb enumeration clears full speed ep0 state
This resolves a bug that was recently reported to me by someone
enumerating a USB 1.1 modem through a high speed hub. I'm a bit
surprised we never saw it before; I think cache/dma timings must
usually be strongly in our favor.
The problem was that the HC was still using the old ep0 maxpacket
value, so when it received an 18 byte device descriptor it would
report a packet overrun and enumeration would fail. The fix is
straightforward: invalidate the HC's old endpoint state when we
change the full speed maxpacket size. (And eventually, we can
remove EHCI and OHCI code coping with usbcore not doing this.)
