CRED: Fix RCU warning due to previous patch fixing __task_cred()'s checks
Commit
8f92054e7ca1 ("CRED: Fix __task_cred()'s lockdep check and banner
comment") fixed the lockdep checks on __task_cred(). This has shown up
a place in the signalling code where a lock should be held - namely that
check_kill_permission() requires its callers to hold the RCU lock.
Fix group_send_sig_info() to get the RCU read lock around its call to
check_kill_permission().
Without this patch, the following warning can occur:

block_dev: always serialize exclusive open attempts
bd_prepare_to_claim() incorrectly allowed multiple attempts for
exclusive open to progress in parallel if the attempting holders are
identical. This triggered BUG_ON() as reported in the following bug.
https://bugzilla.kernel.org/show_bug.cgi?id=16393
__bd_abort_claiming() is used to finish claiming blocks and doesn't
work if multiple openers are inside a claiming block. Allowing
multiple parallel open attempts to continue doesn't gain anything as
those are serialized down in the call chain anyway. Fix it by always
allowing only single open attempt in a claiming block.
This problem can easily be reproduced by adding a delay after
bd_prepare_to_claim() and attempting to mount two partitions of a
disk.

updating broken web addresses that are located in Documentation/*
Some of the addresses date as far far back as 1995 etc... so searching became a bit difficult,
the best way to deal with these is to use web.archive.org to locate these addresses that are outdated.
Now there are also some addresses pointing to .spec files some are located, but some(after searching
on the companies site)where still no where to be found. In this case I just changed the address

phy/marvell: add
88ec048 support
Marvell
88ec048 is a derivative of its 88e1121r device. From the programmer's
perspective, the one major difference is the addition of an additional control
bit in Page 2 Register 16 - used to control the padding of odd nibble
preambles.
This patch adds support for this new device, while inheriting as much code as
possible from the existing 88e1121r implementation.

Maybe some of those people just didn't realize it was disabled in BIOS?
If you tell users that it's a firmware bug then they'll probably just
give up.

Why do you think so? I spent an hour on hunting down the BIOS upgrade,
only to find that it didn't improve anything. It was a day later that I
realized that it might be a BIOS option; and the option was literally
the _last_ option in the whole BIOS setup. :)

(including HP, who wrote this spec) properly check the UUID on entry to the

edac, mc: Improve scrub rate handling
Fortify the interface to not accept negative values, remove
memctrl_int_store() as a result. Also, sanitize bandwidth setting by
making the argument a simple u32 instead of strange u32 pointer being
passed around for no obvious reason. Then, fix error handling and teach
it to return proper error values. Finally, make code more readable,
simplify debug messages.
