o Currently there is no specific alignment restriction in linker script
  and in some cases it can be placed non 4K aligned addresses. This fails
  kexec which checks that segment to be loaded is page aligned.

o I guess, it does not harm data segment to be 4K aligned.

In the case where an open creates the file, we shouldn't be rechecking
permissions to open the file; the open succeeds regardless of what the new
file's mode bits say.

This patch fixes the problem, but only by introducing yet another parameter
to nfsd_create_v3.  This is ugly.  This will be fixed by later patches.

set_mb() is used by set_current_state() which needs mb(), not wmb().  I
think it would be right to assume that set_mb() implies mb(), all arches

If the microcode driver is built in (rather than module) there are some,
ehm, interesting effects happening due to the new "call out to userspace"
behavior that is introduced..  and which runs too early.  The result is a
boot hang; which is really nasty.

The patch below is a minimally safe patch to fix this regression for 2.6.19
by just not requesting actual microcode updates during early boot.  (That
is a good idea in general anyway)

The "real" fix is a lot more complex given the entire cpu hotplug scenario
(during cpu hotplug you normally need to load the microcode as well); but
the interactions for that are just really messy at this point; this fix at
least makes it work and avoids a full detangle of hotplug.

* merom:v2.6/linux:
  x86-64: write IO APIC irq routing entries in correct order
  x86-64: clean up io-apic accesses

This is the x86-64 version of f9dadfa7
that did the same thing on i386.

Since the "mask" bit is in the low word, when we write a new entry, we
need to write the high word first, before we potentially unmask it.

The exception is when we actually want to mask the interrupt, in which
case we want to write the low word first to make sure that the high word
doesn't change while the interrupt routing is still active.

This is just commit 130fe05d ported to
x86-64, for all the same reasons.  It cleans up the IO-APIC accesses in
order to then fix the ordering issues.

We move the accessor functions (that were only used by io_apic.c) out of
a header file, and use proper memory-mapped accesses rather than making
up our own "volatile" pointers.

This reverts commit de09bddb.  It tried
to reserve the MMCONFIG mmio memory ranges, but since the MMCONFIG
information is broken and often bogus (which is why we don't dare use it
most of the time _anyway_), it does more harm than good.

show_mem() was not correctly handling holes in the memory
map.  It was treating the freed sections of the map as
though they contained valid struct page entries.  This
could cause incorrect debugging output or even a kernel
panic.

This patch keeps the struct meminfo around after system
initialization so that show_mem() can use it when
scanning memory.  show_mem() now walks over each bank
of each online node, rather than assuming that each node
contains a single contiguous bank.

After 7.0.33/2.6.16, e1000 suspend/resume left the user with an enabled

Through some experimentation with the similarly built bcm43xx I came to
the conclusion that if the hw/firmware sets a bit in the interrupt
register, an interrupt will only be raised if that bit is included in
the interrupt mask. Hence, the interrupt mask is more like an interrupt
control mask.

This patch changes the comment to reflect that.
