Allows dumping out current register contents from the debug filesystem, and
also allows user to add arbitrary register save points into code. Current
register contents are available under debugfs at:
[debugfs]/pm_debug/registers/current
To add a save point, do following:
From module init (or somewhere before the save call, called only once):
pm_dbg_init_regset(n); // n=1..4, allocates memory for dump area #n
From arbitrary code location:
pm_dbg_regset_save(n); // n=1..4, saves registers to dump area #n
After this, the register dump can be seen under [debugfs]/pm_debug/registers/n

This patch provides the debugfs entries and a function which will be
called by the PM code to register the time spent per domain per
state. Also some new fields are added to the powerdomain struct to
keep the time information.
NOTE: As of v2.6.29, using getnstimeofday() after drivers are
suspended is no longer safe since the timekeeping subsystem is also
suspended as part of the suspend process. Instead use sched_clock()
which on OMAP returns the 32k SYNC timer in nanoseconds.
Also, do not print out status for meta powerdomains (dpll*)

OMAP tags are deprecrated so drop them.
Drop UART config data which decides which UARTs to enable during boot.
This is no longer necessary since serial core code disables clocks
after inactivity.
Background: with new UART idle code, all on-chip UARTs are idled using
a configurable inactivity timer (default 5 seconds.) After the
inactivity timer, UART clocks are disabled automatically.

Currently, highmem is selectable, and you can request an increased
vmalloc area. However, none of this has any effect on the memory
layout since a patch in the highmem series was accidentally dropped.
Moreover, even if you did want highmem, all memory would still be
registered as lowmem, possibly resulting in overflow of the available
virtual mapping space.
The highmem boundary is determined by the highest allowed beginning
of the vmalloc area, which depends on its configurable minimum size
(see commit 60296c71f6c5063e3c1f1d2619ca0b60940162e7 for details on
this).
We should create mappings and initialize bootmem only for low memory,
while the zone allocator must still be told about highmem.
Currently, memory nodes which are completely located in high memory
are not supported. This is not a huge limitation since systems
relying on highmem support are unlikely to have discontiguous memory
with large holes.
[ A similar patch was meant to be merged before commit 5f0fbf9ecaf3
and be available in Linux v2.6.30, however some git rebase screw-up
of mine dropped the first commit of the series, and that goofage
escaped testing somehow as well. -- Nico ]

2.6.31-rc kernels don't boot on my ixp4xx box (ds101), because the libata
driver doesn't find the PCI IDE controller any more. 2.6.30 was fine.
I traced this to a PCI update (1f82de10d6b1d845155363c895c552e61b36b51a)
in 2.6.30-git19. Diffing the kernel boot logs from 2.6.30-git18 and

The specific change in 1f82de10d6b1d845155363c895c552e61b36b51a responsible

Every arch except arm's ixp4xx defines IO_SPACE_LIMIT as an all-bits-one
bitmask, typically -1UL but sometimes only a 16-bit 0x0000ffff. But ixp4xx
defines it as 0xffff0000, which is now causing the PCI failures.
Russell King noted that ixp4xx has 64KB PCI IO space, so IO_SPACE_LIMIT
should be 0x0000ffff. This patch makes that change, which fixes the PCI
failures on my ixp4xx box.
