OMAP3: cpuidle: Add valid field into C-state parameter passing
Different boards benefit differently from the available
seven C-states for cpu idle. In most cases, only few,
properly spaced (in terms of consumption and latency)
C-states are required to make the power management
optimal. Hence we need a possibility to pass which
C-states are actually used for each board.
So added the valid field to cpuidle_params and added
support to 3430sdp, which uses the paramenter passing.

OMAP3: cpuidle: configure latencies/thresholds from board file
The CPUidle C state latencies and thresholds are dependent on various
board specific details. This patch makes it possible to configure
these values from the respective board files.
omap3_pm_init_cpuidle() can now be optionally called from board files
to pass board specific cpuidle parameters. If the board files do not
use this function to pass the params default values are used which
might cause higher consumption dur to wrong state selection by the
governor.
This patch only updates the 3430sdp board files to use

Change the way McBSP registers are updated: use cached values instead of

With this patch, I have finally managed to get rid of all random

that, values read back from McBSP registers to be used for updating them
happened to be errornous.
From the hardware side, the issue appeared to be caused by a relatively high
power requirements of an external USB adapter connected to the board's printer
dedicated USB port.
I think there is one important point that makes this patch worth of applying,
apart from my hardware quality. With the current code, if it ever happens to
any machine, no matter if OMAP1510 or newer, to read incorrect value from a
McBSP register, this wrong value will get written back without any checking.
That can lead to hardware damage if, for example, an input pin is turned into
output as a result.

fs/exec.c: restrict initial stack space expansion to rlimit
When reserving stack space for a new process, make sure we're not
attempting to expand the stack by more than rlimit allows.
This fixes a bug caused by
b6a2fea39318e43fee84fa7b0b90d68bed92d2ba ("mm:
variable length argument support") and unmasked by
fc63cf237078c86214abcb2ee9926d8ad289da9b ("exec: setup_arg_pages() fails
to return errors").
This bug means that when limiting the stack to less the 20*PAGE_SIZE (eg.
80K on 4K pages or 'ulimit -s 79') all processes will be killed before
they start. This is particularly bad with 64K pages, where a ulimit below
1280K will kill every process.
To test, do:
'ulimit -s 15; ls'
before and after the patch is applied. Before it's applied, 'ls' should
be killed. After the patch is applied, 'ls' should no longer be killed.
A stack limit of 15KB since it's small enough to trigger 20*PAGE_SIZE.
Also 15KB not a multiple of PAGE_SIZE, which is a trickier case to handle
correctly with this code.
4K pages should be fine to test with.

edac: mpc85xx fix build regression by removing unused debug code
Some unused, unsupported debug code existed in the mpc85xx EDAC driver
that resulted in a build failure when CONFIG_EDAC_DEBUG was defined:
drivers/edac/mpc85xx_edac.c: In function 'mpc85xx_mc_err_probe':
drivers/edac/mpc85xx_edac.c:1031: error: implicit declaration of function 'edac_mc_register_mcidev_debug'
drivers/edac/mpc85xx_edac.c:1031: error: 'debug_attr' undeclared (first use in this function)
drivers/edac/mpc85xx_edac.c:1031: error: (Each undeclared identifier is reported only once
drivers/edac/mpc85xx_edac.c:1031: error: for each function it appears in.)

edac: mpc85xx fix bad page calculation
Commit
b4846251727a38a7f248e41308c060995371dd05 ("edac: mpc85xx add
mpc83xx support") accidentally broke how a chip select's first and last
page addresses are calculated. The page addresses are being shifted too
far right by PAGE_SHIFT. This results in errors such as:
EDAC MPC85xx MC1: Err addr: 0x003075c0
EDAC MPC85xx MC1: PFN: 0x00000307
EDAC MPC85xx MC1: PFN out of range!
EDAC MC1: INTERNAL ERROR: row out of range (4 >= 4)
EDAC MC1: CE - no information available: INTERNAL ERROR
The vaule of PAGE_SHIFT is already being taken into consideration during
the calculation of the 'start' and 'end' variables, thus it is not
necessary to account for it again when setting a chip select's first and
last page address.
