c117d05cd4 V4L/DVB (7753): saa7134: fix tuner setup
Tuner setup were happening during i2c attach callback. This means that it would
happen on two conditions:

        1) if tuner module weren't load, it will happen at request_module("tuner");

        2) if tuner is not compiled as a module, or it is already loaded
           (for example, on setups with more than one tuner), it will happen
           when saa7134 registers I2C bus.

Due to that, if tuner were loaded, tuner setup will happen _before_ reading
the proper values at tuner eeprom. Since set_addr refuses to change for a tuner
that were previously defined (except if the tuner_addr is set), this were
making eeprom tuner detection useless.

This patch removes tuner type setup from saa7134-i2c, moving it to the proper
place, after taking eeprom into account.

Causes the kexec of a RHEL 5.1 kernel to fail.

root casue: the rhel 5.1 kernel still uses INTx emulation.  and
mptscsih_shutdown doesn't call pci_disable_msi to reenable INTx on kexec path

So call pci_msi_shutdown in the shutdown path to do the same thing to msix

[PATCH 1/2] pci/irq: restore mask_bits in msi shutdown -v3

Yinghai found that kexec'ing a RHEL 5.1 kernel with 2.6.25-rc3+ kernels
prevents his NIC from working.  He bisected to

|   genirq: do not leave interupts enabled on free_irq
|
|   The default_disable() function was changed in commit:
|
|    76d2160147
|    genirq: do not mask interrupts by default
|

For MSI, default_shutdown will call mask_bit for msi device.  All mask bits
will left disabled after free_irq.  Then in the kexec case, the next kernel
can only use msi_enable bit, so all device's MSI can not be used.

So lets to restore the mask bit to its pci reset defined value (enabled) when
we disable the kernels use of msi to be a little friendlier to kexec'd kernels.

Extend msi_set_mask_bit to msi_set_mask_bits to take mask, so we can fully
restore that to 0x00 instead of 0xfe.

cedb27de04 tpm: change Kconfig dependencies from PNPACPI to PNP
There is no "PNPACPI" driver interface as such.  PNPACPI is an internal
backend of PNP, and drivers just use the generic PNP interface.

The drivers should depend on CONFIG_PNP, not CONFIG_PNPACPI.

tpm_nsc.c doesn't use PNP at all, so we can just remove the dependency
completely.  It probably *should* use PNP to discover the device, but until it
does, there's no point in depending on PNP.

c3c52bce69 edac: fix module initialization on several modules 2nd time
I implemented opstate_init() as a inline function in linux/edac.h.

added calling opstate_init() to:
	i82443bxgx_edac.c
	i82860_edac.c
	i82875p_edac.c
	i82975x_edac.c

I wrote a fixed patch of
edac-fix-module-initialization-on-several-modules.patch,
and tested building 2.6.25-rc7 with applying this. It was succeed.
I think the patch is now correct.

2) Remove unneeded function edac_device_find()

3) Added #if 0 around function  edac_pci_find()

4) make the needlessly global edac_pci_generic_check() static

5) Removed function edac_check_mc_devices()

Doug Thompson modified Adrian's patches, to bettern represent
the direction of EDAC, and make them one patch.

94ee1cf5a8 edac: add e752x parameter for sysbus_parity selection
Add a module parameter "sysbus_parity" to allow forcing system bus parity
error checking on or off.  Also add support to automatically disable system
bus parity errors for processors which do not support it.

If the sysbus_parity parameter is specified, sysbus parity detection will be
forced on or off.  If it is not specified, the driver will attempt to look at
the CPU identifier string and determine if the CPU supports system bus parity.
 A blacklist was used instead of a whitelist so that system bus parity would
be enabled by default and to minimize the chances of breaking things for those
people already using the driver which for some reason have a processor that
does not have a valid CPU identifier string.

e68e5b664e random: make mixing interface byte-oriented
Switch add_entropy_words to a byte-oriented interface, eliminating numerous
casts and byte/word size rounding issues.  This also reduces the overall
bit/byte/word confusion in this code.

We now mix a byte at a time into the word-based pool.  This takes four times
as many iterations, but should be negligible compared to hashing overhead.
This also increases our pool churn, which adds some depth against some
theoretical failure modes.

The function name is changed to emphasize pool mixing and deemphasize entropy
(the samples mixed in may not contain any).  extract is added to the core
function to make it clear that it extracts from the pool.

6d38b82740 random: remove some prefetch logic
The urandom output pool (ie the fast path) fits in one cacheline, so
this is pretty unnecessary. Further, the output path has already
fetched the entire pool to hash it before calling in here.

(This was the only user of prefetch_range in the kernel, and it passed
in words rather than bytes!)

1c0ad3d492 random: make backtracking attacks harder
At each extraction, we change (poolbits / 16) + 32 bits in the pool,
or 96 bits in the case of the secondary pools. Thus, a brute-force
backtracking attack on the pool state is less difficult than breaking
the hash. In certain cases, this difficulty may be is reduced to 2^64
iterations.

Instead, hash the entire pool in one go, then feedback the whole hash
(160 bits) in one go. This will make backtracking at least as hard as
inverting the hash.
