2011-04-14leds/leds-regulator.c: fix handling of already enabled regulatorsAntonio Ospite1-0/+4
Make the driver aware of the initial status of the regulator. The leds-regulator driver was ignoring the initial status of the regulator; this resulted in rdev->use_count being incremented to 2 after calling regulator_led_set_value() in the .probe method when a regulator was already enabled at insmod time, which made it impossible to ever disable the regulator.

2011-04-14mm/page_alloc.c: silence build_all_zonelists() section mismatchPaul Mundt1-1/+1
The memory hotplug case involves calling to build_all_zonelists() which in turns calls in to setup_zone_pageset(). The latter is marked __meminit while build_all_zonelists() itself has no particular annotation. build_all_zonelists() is only handed a non-NULL pointer in the case of memory hotplug through an existing __meminit path, so the setup_zone_pageset() reference is always safe. The options as such are either to flag build_all_zonelists() as __ref (as per __build_all_zonelists()), or to simply discard the __meminit annotation from setup_zone_pageset().

2011-04-14fs/partitions/ldm.c: fix oops caused by corrupted partition tableTimo Warns1-4/+12
The kernel automatically evaluates partition tables of storage devices. The code for evaluating LDM partitions (in fs/partitions/ldm.c) contains a bug that causes a kernel oops on certain corrupted LDM partitions. A kernel subsystem seems to crash, because, after the oops, the kernel no longer recognizes newly connected storage devices. The patch validates the value of vblk_size.

2011-04-13avr32: init cannot ignore signals sent by force_sig_info()Matt Fleming1-22/+0
We can delete the code that checks to see if we're sending an ignored signal to init because force_sig_info() already handles this case. force_sig_info() will kill init even if the signal handler is SIG_DFL and the scenario described in the comment where init might "generate the same exception over and over again" cannot occur (force_sig_info() clears SIGNAL_UNKILLABLE to ensure that init will die). Also, the use of is_global_init() is not correct in the multhreaded case, as Oleg Nesterov explains, "is_global_init() is not right in theory, /sbin/init can be multithreaded. And, this doesn't cover the sub-namespace inits... I'd suggest to check SIGNAL_UNKILLABLE, but looking closer I think you can simply remove this code." It seems this code was copied from arch/powerpc in March 2007 in commit 623b0355d5b1 "[AVR32] Clean up exception handling code" but the code was deleted from arch/powerpc in November 2009 in commit a0592d42fe3e "powerpc: kill the obsolete code under is_global_init()" So catch up with powerpc and delete the bogus code.

2011-04-12vm: fix mlock() on stack guard pageLinus Torvalds2-21/+18
Commit 53a7706d5ed8 ("mlock: do not hold mmap_sem for extended periods of time") changed mlock() to care about the exact number of pages that __get_user_pages() had brought it. Before, it would only care about errors. And that doesn't work, because we also handled one page specially in __mlock_vma_pages_range(), namely the stack guard page. So when that case was handled, the number of pages that the function returned was off by one. In particular, it could be zero, and then the caller would end up not making any progress at all. Rather than try to fix up that off-by-one error for the mlock case specially, this just moves the logic to handle the stack guard page into__get_user_pages() itself, thus making all the counts come out right automatically.

2011-04-12Revert "vfs: Export file system uuid via /proc/<pid>/mountinfo"Linus Torvalds2-17/+0
This reverts commit 93f1c20bc8cdb757be50566eff88d65c3b26881f. It turns out that libmount misparses it because it adds a '-' character in the uuid string, which libmount then incorrectly confuses with the separator string (" - ") at the end of all the optional arguments. Upstream libmount (in the util-linux tree) has been fixed, but until that fix actually percolates up to users, we'd better not expose this change in the kernel. Let's revisit this later (possibly by exposing the UUID without any '-' characters in it, avoiding the user-space bug).

2011-04-12cifs: don't allow mmap'ed pages to be dirtied while under writeback (try #3)Jeff Layton3-36/+33
This is more or less the same patch as before, but with some merge conflicts fixed up. If a process has a dirty page mapped into its page tables, then it has the ability to change it while the client is trying to write the data out to the server. If that happens after the signature has been calculated then that signature will then be wrong, and the server will likely reset the TCP connection. This patch adds a page_mkwrite handler for CIFS that simply takes the page lock. Because the page lock is held over the life of writepage and writepages, this prevents the page from becoming writeable until the write call has completed. With this, we can also remove the "sign_zero_copy" module option and always inline the pages when writing.

2011-04-12mfd: Fetch cell pointer from platform_device->mfd_cellSamuel Ortiz4-4/+31
In order for MFD drivers to fetch their cell pointer but also their platform data one, an mfd cell pointer is added to the platform_device structure. That allows all MFD sub devices drivers to be MFD agnostic, unless they really need to access their MFD cell data. Most of them don't, especially the ones for IPs used by both MFD and non MFD SoCs.

2011-04-12[CIFS] Warn on requesting default security (ntlm) on mountSteve French1-0/+11
Warn once if default security (ntlm) requested. We will update the default to the stronger security mechanism (ntlmv2) in 2.6.41. Kerberos is also stronger than ntlm, but more servers support ntlmv2 and ntlmv2 does not require an upcall, so ntlmv2 is a better default.
