V4L/DVB (12206): get_dvb_firmware: Correct errors in MPC718 firmware extraction logic
The extraction routine for the MPC718 "firmware" had 2 bugs in it, where one
bug masked the effect of the other. The loop iteration should have set
$prevlen = $currlen at the end of the loop, and the if() check should have used
&& instead of || for deciding if the firmware length is reasonable.

block: don't merge requests of different failfast settings
Block layer used to merge requests and bios with different failfast
settings. This caused regular IOs to fail prematurely when they were
merged into failfast requests for readahead.
Niel Lambrechts could trigger the problem semi-reliably on ext4 when
resuming from STR. ext4 uses readahead when reading inodes and
combined with the deterministic extra SATA PHY exception cycle during
resume on the specific configuration, non-readahead inode read would
fail causing ext4 errors. Please read the following thread for
details.
http://lkml.org/lkml/2009/5/23/21
This patch makes block layer reject merging if the failfast settings

MIPS: 64-bit: Fix o32 core dump
If an o32 process generates a core dump on a 64 bit kernel, the core file
will not be correctly recognized. This is because ELF_CORE_COPY_REGS and
ELF_CORE_COPY_TASK_REGS are not correctly defined for o32 and will use
the default register set which would be CONFIG_64BIT in asm/elf.h.
So we'll switch to use the right register defines in this situation by
checking for WANT_COMPAT_REG_H and use the right defines of
ELF_CORE_COPY_REGS and ELF_CORE_COPY_TASK_REGS.

MIPS: BC47xx: Fix SSB irq setup
The current ssb irq setup in ssb_mipscore_init has the problem that it
configures some device on some irq without checking that the irq is not
taken by an other device.
For example in my case PCI host is on irq 0 and IPSEC on irq 3.
The current code:
- store in dev->irq that IPSEC irq is 3 + 2
- do a set_irq 0->3 on PCI host
But now IPSEC irq is not routed anymore to the mips code and dev->irq is
wrong. This causes a problem described in [1].
This patch tries to solve the problem by making set_irq configure the
device we want to take the irq on the shared irq0. The previous example
becomes:
- store in dev->irq that IPSEC irq is 3 + 2
- do a set_irq 0->3 on PCI host:
- irq 3 is already taken by IPSEC. do a set_irq 3->0 on IPSEC
I also added some code to print the irq configuration after irq setup to
allow easier debugging. And I add extra checking in ssb_mips_irq to report
device without irq or device with not routed irq.

NFSD: Don't hold unrefcounted creds over call to nfsd_setuser()
nfsd_open() gets an unrefcounted pointer to the current process's effective
credentials at the top of the function, then calls nfsd_setuser() via
fh_verify() - which may replace and destroy the current process's effective
credentials - and then passes the unrefcounted pointer to dentry_open() - but
the credentials may have been destroyed by this point.
Instead, the value from current_cred() should be passed directly to
dentry_open() as one of its arguments, rather than being cached in a variable.
Possibly fh_verify() should return the creds to use.

parisc: fix "delay!" timer handling
Rewrote timer_interrupt() to properly handle the "delayed!" case.
If we used floating point math to compute the number of ticks that had
elapsed since the last timer interrupt, it could take up to 12K cycles
(emperical!) to handle the interrupt. Existing code assumed it would
never take more than 8k cycles. We end up programming Interval Timer
to a value less than "current" cycle counter. Thus have to wait until
Interval Timer "wrapped" and would then get the "delayed!" printk that
I moved below.
Since we don't really know what the upper limit is, I prefer to read
CR16 again after we've programmed it to make sure we won't have to
wait for CR16 to wrap.
Further, the printk was between reading CR16 (cycle couner) and writing CR16
(the interval timer). This would cause us to continue to set the interval
timer to a value that was "behind" the cycle counter. Rinse and repeat.
So no printk's between reading CR16 and setting next interval timer.

x86: add boundary check for 32bit res before expand e820 resource to alignment
fix hang with HIGHMEM_64G and 32bit resource. According to hpa and
Linus, use (resource_size_t)-1 to fend off big ranges.

x86: fix power-of-2 round_up/round_down macros
These macros had two bugs:
- the type of the mask was not correctly expanded to the full size of
the argument being expanded, resulting in possible loss of high bits
when mixing types.
- the alignment argument was evaluated twice, despite the macro looking
like a fancy function (but it really does need to be a macro, since
it works on arbitrary integer types)
Noticed by Peter Anvin, and with a fix that is a modification of his
suggestion (bug noticed by Yinghai Lu).

Btrfs: honor nodatacow/sum mount options for new files
The btrfs attr patches unconditionally inherited the inode flags field
without honoring nodatacow and nodatasum. This fix makes sure
we properly record the nodatacow/sum mount options in new inodes.
