2011-02-02fs: make block fiemap mapping length at least blocksize longJosef Bacik
Some filesystems don't deal well with being asked to map less than blocksize blocks (GFS2 for example). Since we are always mapping at least blocksize sections anyway, just make sure len is at least as big as a blocksize so we don't trip up any filesystems.

Changes in e401f1761 ("memcg: modify accounting function for supporting THP better") adds nr_pages to support multiple page size in memory_cgroup_charge_statistics. But counting the number of event nees abs(nr_pages) for increasing counters. This patch fixes event counting.

2011-02-02memcg: never OOM when charging huge pagesJohannes Weiner
Huge page coverage should obviously have less priority than the continued execution of a process. Never kill a process when charging it a huge page fails.

2011-02-02memcg: prevent endless loop when charging huge pages to near-limit groupJohannes Weiner
If reclaim after a failed charging was unsuccessful, the limits are checked again, just in case they settled by means of other tasks. This is all fine as long as every charge is of size PAGE_SIZE, because in that case, being below the limit means having at least PAGE_SIZE bytes available. But with transparent huge pages, we may end up in an endless loop where charging and reclaim fail, but we keep going because the limits are not yet exceeded, although not allowing for a huge page. Fix this up by explicitely checking for enough room, not just whether we are within limits.

2011-02-02memcg: prevent endless loop when charging huge pagesJohannes Weiner
The charging code can encounter a charge size that is bigger than a regular page in two situations: one is a batched charge to fill the per-cpu stocks, the other is a huge page charge. This code is distributed over two functions, however, and only the outer one is aware of huge pages. In case the charging fails, the inner function will tell the outer function to retry if the charge size is bigger than regular pages--assuming batched charging is the only case. And the outer function will retry forever charging a huge page. This patch makes sure the inner function can distinguish between batch charging and a single huge page charge. It will only signal another attempt if batch charging failed, and go into regular reclaim when it is called on behalf of a huge page.

2011-02-02thp: fix unsuitable behavior for hwpoisoned tail pageJin Dongming
When a tail page of THP is poisoned, memory-failure will do nothing except setting PG_hwpoison, while the expected behavior is that the process, who is using the poisoned tail page, should be killed. The above problem is caused by lru check of the poisoned tail page of THP. Because PG_lru flag is only set on the head page of THP, the check always consider the poisoned tail page as NON lru page. So the lru check for the tail page of THP should be avoided, as like as hugetlb. This patch adds !PageTransCompound() before lru check for THP, because of the check (!PageHuge() && !PageTransCompound()) the whole branch could be optimized away at build time when both hugetlbfs and THP are set with "N" (or in archs not supporting either of those).

2011-02-02thp: fix the wrong reported address of hwpoisoned hugepagesJin Dongming
When the tail page of THP is poisoned, the head page will be poisoned too. And the wrong address, address of head page, will be sent with sigbus always. So when the poisoned page is used by Guest OS which is running on KVM, after the address changing(hva->gpa) by qemu, the unexpected process on Guest OS will be killed by sigbus. What we expected is that the process using the poisoned tail page could be killed on Guest OS, but not that the process using the healthy head page is killed. Since it is not good to poison the healthy page, avoid poisoning other than the page which is really poisoned. (While we poison all pages in a huge page in case of hugetlb, we can do this for THP thanks to split_huge_page().) Here we fix two parts: 1. Isolate the poisoned page only to make sure the reported address is the address of poisoned page. 2. make the poisoned page work as the poisoned regular page.

2011-02-02thp: fix splitting of hwpoisoned hugepagesJin Dongming
The poisoned THP is now split with split_huge_page() in collect_procs_anon(). If kmalloc() is failed in collect_procs(), split_huge_page() could not be called. And the work after split_huge_page() for collecting the processes using poisoned page will not be done, too. So the processes using the poisoned page could not be killed. The condition becomes worse when CONFIG_DEBUG_VM == "Y". Because the poisoned THP could not be split, system panic will be caused by VM_BUG_ON(PageTransHuge(page)) in try_to_unmap(). This patch does: 1. move split_huge_page() to the place before collect_procs(). This can be sure the failure of splitting THP is caused by itself. 2. when splitting THP is failed, stop the operations after it. This can avoid unexpected system panic or non sense works.

noswapaccount couldn't be used to control memsw for both on/off cases so we have added swapaccount[=0|1] parameter. This way we can turn the feature in two ways noswapaccount resp. swapaccount=0.

__setup based kernel command line parameters handlers which are handled in obsolete_checksetup are provided with the parameter value including = (more precisely everything right after the parameter name). This means that the current implementation of swapaccount[=1|0] doesn't work at all because if there is a value for the parameter then we are testing for "0" resp. "1" but we are getting "=0" resp. "=1" and if there is no parameter value we are getting an empty string rather than NULL. The original noswapccount parameter, which doesn't care about the value, works correctly.

Accidently busted a while back. We'll be creating objects that aren't necessary here, but, they're never used so no harm.. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2011-02-02cifs: fix length vs. total_read confusion in cifs_demultiplex_threadJeff Layton
length at this point is the length returned by the last kernel_recvmsg call. total_read is the length of all of the data read so far. length is more or less meaningless at this point, so use total_read for everything.

2011-02-01OMAP3: Devkit8000: Change lcd power pinThomas Weber
This patch fixes a wrongly used lcd enable pin. The Devkit8000 uses twl4030_ledA configured as output gpio only for the lcd enable line. twl4030_gpio.1 is used through the generic gpio functions while ledA is used via low level twl4030 calls. This patch removes the low level calls and use the generic gpio functions for initialization and use of ledA. This patch also fixes a bug where the lcd would not power down when blanking. Further this patch fixes an indentation issue. The comment line uses eight whitespace and is replaced with a hard tab. gpio_request + gpio_direction_output are replaced with gpio_request_one. The return value of gpio_request_one is used to set the value of the gpio to -EINVAL when unsuccessful, so that gpio_is_valid can detect the unsuccessful request. But already successful requested gpios are not freed.

2011-02-01arm: mach-omap2: board-rm680: fix rm680_vemmc regulator constraintsAaro Koskinen
With the commit 757902513019e6ee469791ff76f954b19ca8d036 (regulator: Factor out voltage set operation into a separate function) fixed voltage regulator setup will fail if there are voltage constraints defined. This made MMC unusable on this board. Fix by just deleting those redundant constraints.
