* Merge branch 'akpm' (Andrew's patch-bomb)Linus Torvalds2012-04-051-0/+70
|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Merge batch of fixes from Andrew Morton: "The simple_open() cleanup was held back while I wanted for laggards to merge things. I still need to send a few checkpoint/restore patches. I've been wobbly about merging them because I'm wobbly about the overall prospects for success of the project. But after speaking with Pavel at the LSF conference, it sounds like they're further toward completion than I feared - apparently davem is at the "has stopped complaining" stage regarding the net changes. So I need to go back and re-review those patchs and their (lengthy) discussion." * emailed from Andrew Morton <akpm@linux-foundation.org>: (16 patches) memcg swap: use mem_cgroup_uncharge_swap fix backlight: add driver for DA9052/53 PMIC v1 C6X: use set_current_blocked() and block_sigmask() MAINTAINERS: add entry for sparse checker MAINTAINERS: fix REMOTEPROC F: typo alpha: use set_current_blocked() and block_sigmask() simple_open: automatically convert to simple_open() scripts/coccinelle/api/simple_open.cocci: semantic patch for simple_open() libfs: add simple_open() hugetlbfs: remove unregister_filesystem() when initializing module drivers/rtc/rtc-88pm860x.c: fix rtc irq enable callback fs/xattr.c:setxattr(): improve handling of allocation failures fs/xattr.c:listxattr(): fall back to vmalloc() if kmalloc() failed fs/xattr.c: suppress page allocation failure warnings from sys_listxattr() sysrq: use SEND_SIG_FORCED instead of force_sig() proc: fix mount -t proc -o AAA

| * | setlocalversion: Use "grep -q" instead of piping output to "read dummy"Roland Dreier2012-03-261-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In some circumstances (eg when running a build in an emacs shell buffer), I get a spew of messages like grep: writing output: Broken pipe from setlocalversion, because the "read" subshell apparently exits as soon as it reads one line and gives EPIPE to grep. It's not clear to me why this way of writing the check was used instead of just using grep -q to suppress output, but unless there is some deep reason I don't know, this way looks cleaner to me anyway, and gets rid of the ugly message spew. (I double checked at http://pubs.opengroup.org/onlinepubs/009604499/utilities/grep.html and "grep -q" is specified in POSIX / SuS, so hopefully even people cross-compiling the kernel on some bizarre host OS can't complain about this change) Signed-off-by: Roland Dreier <roland@purestorage.com> Signed-off-by: Michal Marek <mmarek@suse.cz>

| * | scripts/Kbuild.include: Fix portability problem of "echo -e"Bernhard Walle2012-03-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | "echo -e" is a GNU extension. When cross-compiling the kernel on a BSD-like operating system (Mac OS X in my case), this doesn't work. One could install a GNU version of echo, put that in the $PATH before the system echo and use "/usr/bin/env echo", but the solution with printf is simpler. Since it is no disadvantage on Linux, I hope that gets accepted even if cross-compiling the Linux kernel on another Unix operating system is quite a rare use case.

The cause of this behavior is that choice's novelty are computed statically right after the saved configuration has been read. At this point, the new dependency's value is still unknown and asserted to be `no'. Moreover, no update to this decision is made afterward. Correct this by dynamically evaluating a choice's novelty, and removing the static evaluation.

This prevents us requesting further perentheses around the following: #define PMEM_IS_FREE(id, index) !(pmem[id].bitmap[index].allocated) For now add logical and bitwise not and unary minus.
