We want to use dev_to_node() later on, to be aware of the 'home node'
of the GSI in question.
[ Impact: cleanup, prepare the IRQ code to be more NUMA aware ]

The virtio-rng drivers checks for spurious callbacks. Since
callbacks can be implemented via shared interrupts (e.g. PCI) this
could lead to guest kernel oopses with lots of virtio devices.

Bela Lubkin noticed that the statistics for send IPMB and LAN commands
in the IPMI driver could be incremented even if an error occurred. Move
the increments to the proper place to avoid this.
Also add some statistics for retransmissions that failed, and some little
helper functions to neaten up the code a little.

The IPMI driver would attempt to use the event buffer even if that
didn't exist on the BMC. This patch modified the IPMI driver to check
for the event buffer's existence before trying to use it.

agp: zero pages before sending to userspace

AGP pages might be mapped into userspace finally, so the pages should be
set to zero before userspace can use it. Otherwise there is potential
information leakage.

This reverts commit 1c55f18717304100a5f624c923f7cb6511b4116d.
Ingo Brueckl was assuming that reverting to 1:1 mapping for chars >= 128
was not useful, but it happens to be: due to the limitations of the
Linux console, when a blind user wants to read BIG5 on it, he has no
other way than loading a font without SFM and let the 1:1 mapping permit
the screen reader to get the BIG5 encoding.

/dev/mem mmap code was doing memtype reserve/free for a while now.
Recently we added memtype tracking in remap_pfn_range, and /dev/mem mmap
uses it indirectly. So, we don't need seperate tracking in /dev/mem code
any more. That means another ~100 lines of code removed :-).

mxser_check_modem_status is called with tty parameter, so the
reference should be increased by callers already -- for ioctl
syscall it is held whole time gap since open to close, for
interrupt, the reference count is increased in the irq handler.
There is no tty_kref_put in that function, so this also fixes
a refcounting bug.

There is no ioremap'ing or anything in timeriomem-rng.c as I foolishly
used already remapped virtual addresses instead of passing the physical
address to be polled.
This patch fixes this flaw and lets developers do the Right Thing(tm).

We are wasting 2 words in signal_struct without any reason to implement
task_pgrp_nr() and task_session_nr().
task_session_nr() has no callers since
2e2ba22ea4fd4bb85f0fa37c521066db6775cbef, we can remove it.
task_pgrp_nr() is still (I believe wrongly) used in fs/autofsX and
fs/coda.
This patch reimplements task_pgrp_nr() via task_pgrp_nr_ns(), and kills
__pgrp/__session and the related helpers.
The change in drivers/char/tty_io.c is cosmetic, but hopefully makes sense
anyway.

hpet_calibrate() has a possibility of miss-calibration due to SMI. If SMI
interrupts in the while loop of calibration, then return value will be
big. This change calibrates until stabilizing by the return value with a
small value.

Align rekey_work. Even though it's infrequent, we may as well line it up.
