omap: Remove DEBUG_FS dependency for mux name checking

The check for a valid mux name should be performed regardless of whether
DEBUG_FS is enabled or not. Otherwise without DEBUG_FS, we get:

Regulators from the board file mmc-twl4030.c to the

Moving GPIO code to the driver makes the board initialisation
code independent of when GPIO's are defined.  That makes the
board initialisation now entirely independent of its original

Moving Voltage Regulator code to the driver allows for further
development of regulator support in the core MMC code.  It also
permits the MMC core to be compiled as a module, because the

2. int nr_parts

10 years agoomap: McBSP: Use cache when modifying individual register bits
Janusz Krzysztofik [Mon, 15 Feb 2010 18:03:33 +0000]
omap: McBSP: Use cache when modifying individual register bits

Change the way McBSP registers are updated: use cached values instead of
relying upon those read back from the device.

With this patch, I have finally managed to get rid of all random
playback/recording hangups on my OMAP1510 based Amstrad Delta hardware. Before
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.

Applies on top of patch 3 from this series:

omap: iommu: fix incorrect address for supersection 1st entry

There was a potential risk that the following "memset" could override
its range if a given address was not the 1st entry of a
supersection. This is not the case for "iovmm".

10 years agofs/exec.c: restrict initial stack space expansion to rlimit
Michael Neuling [Wed, 10 Feb 2010 21:56:42 +0000]
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 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.

10 years agommc_test: block addressed cards
Johan Kristell [Wed, 10 Feb 2010 21:56:34 +0000]
mmc_test: block addressed cards

This patch fixes a bug in the multiblock write tests where the written
data is read back for verifying one block at a time.  The tests in
mmc_test assumes that all cards are byte addressable.

This will cause the multi block write tests to fail, leading the user of
the mmc_test driver thinking there is something wrong with the sdhci
driver they are testing.

The start address for the block is calculated as: blocknum * 512. For
block addressable cards the blocknum alone should be used.

tpm_infineon: fix suspend/resume handler for pnp_driver

When suspending, tpm_infineon calls the generic suspend function of the
TPM framework.  However, the TPM framework does not return and the system
hangs upon suspend.  When sending the necessary command "TPM_SaveState"
directly within the driver, suspending and resuming works fine.
