2011-11-01Revert "HID: multitouch: decide if hid-multitouch needs to handle mt devices"Henrik Rydberg
This reverts commit 0db3bfc72adf0c (""HID: multitouch: decide if hid-multitouch needs to handle mt devices"). The generic detection of hid-mt devices has two major flaws, and was merged prematurely. Firstly, the hid-multitouch gets loaded even when the device is handled by a special device. Secondly, the patch only partially duplicates the device whitelist already present in hid-core, effectively rendering a number of devices non-functional.

2011-11-01HID: drivers/hid/hid-roccat.c: eliminate a null pointer dereferenceJulia Lawall
It is not possible to take the lock in device if device is NULL. The mutex_lock is thus moved after the NULL test. New error handling labels are added at the end to differentiate between the cases where different sets of locks should be unlocks, and between whether or not reader should be freed (only on error). The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r@ expression E, E1; identifier f; statement S1,S2,S3; @@ if (E == NULL) { ... when != if (E == NULL || ...) S1 else S2 when != E = E1 *E->f ... when any return ...; } else S3 // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

2011-11-01EDAC: Fix incorrect edac mode reporting in sb_edacMark A. Grondona
The edac driver for Sandy Bridge was found to be reporting "FPM" for edac_mode, which clearly doesn't make sense. It was found that sb_edac.c:get_dimm_config was reusing a variable for both mem_type and edac_type, and thus was overwriting the value after setting it correctly. This patch fixes that issue.

2011-11-01edac: Add an experimental new driver to support Sandy Bridge CPU'sMauro Carvalho Chehab
This driver is known to work on mine and Tony's test environments, using software error injection, and a partial hardware/software error injection tool. There's no broader range test yet to double check if the error decoding logic will actually point to the right DIMM, so use it with care. More tests are required to be sure that the driver will work on all different types of memory configurations. If you're willing to risk using it, I suggest you to enable EDAC debugs for your test machines, as the debug logs helps to track what's going inside the driver. Please feed me with bug reports, if you notice that the driver is miss-behaving. Tested-by: Tony Luck <tony.luck@intel.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2011-11-01i7core_edac: return -ENODEV if no MC is foundMauro Carvalho Chehab
Nehalem-EX uses a different memory controller. However, as the memory controller is not visible on some Nehalem/Nehalem-EP, we need to indirectly probe via a X58 PCI device. The same devices are found on (some) Nehalem-EX. So, on those machines, the probe routine needs to return -ENODEV, as the actual Memory Controller registers won't be detected.

2011-10-31epoll: fix spurious lockdep warningsNelson Elhage
epoll can acquire recursively acquire ep->mtx on multiple "struct eventpoll"s at once in the case where one epoll fd is monitoring another epoll fd. This is perfectly OK, since we're careful about the lock ordering, but it causes spurious lockdep warnings. Annotate the recursion using mutex_lock_nested, and add a comment explaining the nesting rules for good measure. Recent versions of systemd are triggering this, and it can also be demonstrated with the following trivial test program: --------------------8<-------------------- int main(void) { int e1, e2; struct epoll_event evt = { .events = EPOLLIN }; e1 = epoll_create1(0); e2 = epoll_create1(0); epoll_ctl(e1, EPOLL_CTL_ADD, e2, &evt); return 0; } --------------------8<-------------------- Reported-by: Paul Bolle <pebolle@tiscali.nl> Tested-by: Paul Bolle <pebolle@tiscali.nl> Signed-off-by: Nelson Elhage <nelhage@nelhage.com> Acked-by: Jason Baron <jbaron@redhat.com> Cc: Dave Jones <davej@redhat.com> Cc: Davide Libenzi <davidel@xmailserver.org> Cc: <stable@kernel.org> Cc: <stable@vger.kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
