2012-06-11edac: Do alignment logic properly in edac_align_ptr()Chris Metcalf
The logic was checking the sizeof the structure being allocated to determine whether an alignment fixup was required. This isn't right; what we actually care about is the alignment of the actual pointer that's about to be returned. This became an issue recently because struct edac_mc_layer has a size that is not zero modulo eight, so we were taking the correctly-aligned pointer and forcing it to be misaligned. On Tile this caused an alignment exception. Signed-off-by: Chris Metcalf <cmetcalf@tilera.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2012-06-11edac: avoid mce decoding crash after edac driver unloadedChen Gong
Some edac drivers register themselves as mce decoders via notifier_chain. But in current notifier_chain implementation logic, it doesn't accept same notifier registered twice. If so, it will be wrong when adding/removing the element from the list. For example, on one SandyBridge platform, remove module sb_edac and then trigger one error, it will hit oops because it has no mce decoder registered but related notifier_chain still points to an invalid callback function. Here is an example: Call Trace: [<ffffffff8150ef6a>] atomic_notifier_call_chain+0x1a/0x20 [<ffffffff8102b936>] mce_log+0x46/0x180 [<ffffffff8102eaea>] apei_mce_report_mem_error+0x4a/0x60 [<ffffffff812e19d2>] ghes_do_proc+0x192/0x210 [<ffffffff812e2066>] ghes_proc+0x46/0x70 [<ffffffff812e20d8>] ghes_notify_sci+0x48/0x80 [<ffffffff8150ef05>] notifier_call_chain+0x55/0x80 [<ffffffff81076f1a>] __blocking_notifier_call_chain+0x5a/0x80 [<ffffffff812aea11>] ? acpi_os_wait_events_complete+0x23/0x23 [<ffffffff81076f56>] blocking_notifier_call_chain+0x16/0x20 [<ffffffff812ddc4d>] acpi_hed_notify+0x19/0x1b [<ffffffff812b16bd>] acpi_device_notify+0x19/0x1b [<ffffffff812beb38>] acpi_ev_notify_dispatch+0x67/0x7f [<ffffffff812aea3a>] acpi_os_execute_deferred+0x29/0x36 [<ffffffff81069dc2>] process_one_work+0x132/0x450 [<ffffffff8106bbcb>] worker_thread+0x17b/0x3c0 [<ffffffff8106ba50>] ? manage_workers+0x120/0x120 [<ffffffff81070aee>] kthread+0x9e/0xb0 [<ffffffff81514724>] kernel_thread_helper+0x4/0x10 [<ffffffff81070a50>] ? kthread_freezable_should_stop+0x70/0x70 [<ffffffff81514720>] ? gs_change+0x13/0x13 Code: f3 49 89 d4 45 85 ed 4d 89 c6 48 8b 0f 74 48 48 85 c9 75 17 eb 41 0f 1f 80 00 00 00 00 41 83 ed 01 4c 89 f9 74 22 4d 85 ff 74 1d <4c> 8b 79 08 4c 89 e2 48 89 de 48 89 cf ff 11 4d 85 f6 74 04 41 RIP [<ffffffff8150eef6>] notifier_call_chain+0x46/0x80 RSP <ffff88042868fb20> CR2: ffffffffa01af838 ---[ end trace 0100930068e73e6f ]--- BUG: unable to handle kernel paging request at fffffffffffffff8 IP: [<ffffffff810705b0>] kthread_data+0x10/0x20 PGD 1a0d067 PUD 1a0e067 PMD 0 Oops: 0000 [#2] SMP Only i7core_edac and sb_edac have such issues because they have more than one memory controller which means they have to register mce decoder many times.

git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu into core/urgent Merge RCU fixes from Paul E. McKenney: " This series has four patches, the major point of which is to eliminate some slowdowns (including boot-time slowdowns) resulting from some RCU_FAST_NO_HZ changes. The issue with the changes is that posting timers from the idle loop has no effect if the CPU has entered dyntick-idle mode because the CPU has already computed its wakeup time, and posting a timer does not cause it to be recomputed. The short-term fix is for RCU to precompute the timeout value so that the CPU's calculation is correct. " Signed-off-by: Ingo Molnar <mingo@kernel.org>

2012-06-10r8169: avoid NAPI scheduling delay.françois romieu
While reworking the r8169 driver a few months ago to perform the smallest amount of work in the irq handler, I took care of avoiding any irq mask register operation in the slow work dedicated user context thread. The slow work thread scheduled an extra round of NAPI work which would ultimately set the irq mask register as required, thus keeping such irq mask operations in the NAPI handler. It would eventually race with the irq handler and delay NAPI execution for - assuming no further irq - a whole ksoftirqd period. Mildly a problem for rare link changes or corner case PCI events. The race was always lost after the last bh disabling lock had been removed from the work thread and people started wondering where those pesky "NOHZ: local_softirq_pending 08" messages came from. Actually the irq mask register _can_ be set up directly in the slow work thread.

2012-06-10drm/radeon: fix tiling and command stream checking on evergreen v3Jerome Glisse
Fix regresson since the introduction of command stream checking on evergreen (thread referenced below). Issue is cause by ddx allocating bo with formula width*height*bpp while programming the GPU command stream with ALIGN(height, 8). In some case (where page alignment does not hide the extra size bo should be according to height alignment) the kernel will reject the command stream. This patch reprogram the command stream to slice - 1 (slice is a derivative value from height) which avoid rejecting the command stream while keeping the value of command stream checking from a security point of view. This patch also fix wrong computation of layer size for 2D tiled surface. Which should fix issue when 2D color tiling is enabled. This dump the radeon KMS_DRIVER_MINOR so userspace can know if they are on a fixed kernel or not. https://lkml.org/lkml/2012/6/3/80 https://bugs.freedesktop.org/show_bug.cgi?id=50892 https://bugs.freedesktop.org/show_bug.cgi?id=50857 !!!

2012-06-09net: Make linux/tcp.h C++ friendly (trivial)Paul Pluzhnikov
I originally sent this patch to <trivial@kernel.org>, but Jiri Kosina did not feel that this is fully appropriate for the trivial tree. Using linux/tcp.h from C++ results in: cat t.cc #include <linux/tcp.h> int main() { } g++ -c t.cc In file included from t.cc:1: /usr/include/linux/tcp.h:72: error: '__u32 __fswab32(__u32)' cannot appear in a constant-expression /usr/include/linux/tcp.h:72: error: a function call cannot appear in a constant-expression ... Attached trivial patch fixes this problem. Tested: - the t.cc above compiles with g++ and - the following program generates the same output before/after the patch: #include <linux/tcp.h> #include <stdio.h> int main () { #define P(a) printf("%s: %08x\n", #a, (int)a) P(TCP_FLAG_CWR); P(TCP_FLAG_ECE); P(TCP_FLAG_URG); P(TCP_FLAG_ACK); P(TCP_FLAG_PSH); P(TCP_FLAG_RST); P(TCP_FLAG_SYN); P(TCP_FLAG_FIN); P(TCP_RESERVED_BITS); P(TCP_DATA_OFFSET); #undef P return 0; } Signed-off-by: Paul Pluzhnikov <ppluzhnikov@google.com> Signed-off-by: David S.

2012-06-09x86, um: Correct syscall table type attributes breaking gcc 4.8Martin Pelikan
The latest GCC 4.8 does some more checking on type attributes that break the build for ARCH=um -> fill them in. Specifically, the "asmlinkage" attributes is now tested for consistency.

2012-06-09NFS: Use the NFS_DEFAULT_VERSION for v2 and v3 mountsBryan Schumaker
Older versions of nfs utils don't always pass a "vers=" mount option for NFS. This chould lead to attempts at using NFS v0 due to a zeroed out nfs_parsed_mount_data struct. I solve this by setting the default NFS version to NFS_DEFAULT_VERSION in the v2 and v3 cases (v4 has already been taken care of by a similar patch).

2012-06-09NFS: fix directio refcount bug on commitFred Isaman
This reverts a hunk from commit 04277086577 "NFS: Clean up - Simplify reference counting in fs/nfs/direct.c" The cleanups in that patch affect the write path, but by the time processing hits commit the removed reference has been added back by nfs_scan_commit_list(). Without this reversion, any page that is sent to commit holds on to an unbalanced reference that is never freed. The immediate effect is an imbalance over the wire between OPENs and CLOSEs.
