2011-06-09sparc32, leon: bugfix in LEON SMP interrupt initDaniel Hellstrom1-0/+16
During converting per-cpu ticker to genirq layer some IRQ initialization code was removed by commit 2cf9530420e446bb61f665d02afeb81070106900 ("sparc32,leon: per-cpu ticker use genirq per-cpu handler"). This patch reintroduces the code at the same place it was removed from. IRQ12 - IRQ14 will crash on LEON SMP without this patch because it will run the SUN4M IRQ trap handler.

2011-06-09sparc32, sun4m: bugfix in SMP IPI traphandlerDaniel Hellstrom1-2/+2
Three new IPIs were introduced by commit ecbc42b70acbc6327adefe9635db93fcf62bf59d ("sparc32, sun4m: Implemented SMP IPIs support for SUN4M machines"), the old handler was already prepared for IPIs but handled only IRQ14 and IRQ13, this patch adds support for the new IPI at IRQ12. The IPI trap handler looks at the mask rather than the pending IRQ/IPI, this bug may have masked the problem above, introduced by the same commit.

2011-06-09ipv4: Fix packet size calculation for raw IPsec packets in __ip_append_dataSteffen Klassert1-3/+3
We assume that transhdrlen is positive on the first fragment which is wrong for raw packets. So we don't add exthdrlen to the packet size for raw packets. This leads to a reallocation on IPsec because we have not enough headroom on the skb to place the IPsec headers. This patch fixes this by adding exthdrlen to the packet size whenever the send queue of the socket is empty.

2011-06-09exec: delay address limit change until point of no returnMathias Krause3-6/+1
Unconditionally changing the address limit to USER_DS and not restoring it to its old value in the error path is wrong because it prevents us using kernel memory on repeated calls to this function. This, in fact, breaks the fallback of hard coded paths to the init program from being ever successful if the first candidate fails to load. With this patch applied switching to USER_DS is delayed until the point of no return is reached which makes it possible to have a multi-arch rootfs with one arch specific init binary for each of the (hard coded) probed paths. Since the address limit is already set to USER_DS when start_thread() will be invoked, this redundancy can be safely removed.

2011-06-09Btrfs: don't map extent buffer if path->skip_locking is setJosef Bacik1-3/+7
Arne's scrub stuff exposed a problem with mapping the extent buffer in reada_for_search. He searches the commit root with multiple threads and with skip_locking set, so we can race and overwrite node->map_token since node isn't locked. So fix this so that we only map the extent buffer if we don't already have a map_token and skip_locking isn't set. Without this patch scrub would panic almost immediately, with the patch it doesn't panic anymore. Thanks, Reported-by: Arne Jansen <[email protected]> Signed-off-by: Josef Bacik <[email protected]>

Currently it is possible that snd_soc_new_{mixer,mux,pga} is called with a DAPM context not matching the widgets context.

2011-06-09powerpc: Force page alignment for initrd reserved memoryBenjamin Herrenschmidt4-32/+43
When using 64K pages with a separate cpio rootfs, U-Boot will align the rootfs on a 4K page boundary. When the memory is reserved, and subsequent early memblock_alloc is called, it will allocate memory between the 64K page alignment and reserved memory. When the reserved memory is subsequently freed, it is done so by pages, causing the early memblock_alloc requests to be re-used, which in my case, caused the device-tree to be clobbered. This patch forces the reserved memory for initrd to be kernel page aligned, and will move the device tree if it overlaps with the range extension of initrd. This patch will also consolidate the identical function free_initrd_mem() from mm/init_32.c, init_64.c to mm/mem.c, and adds the same range extension when freeing initrd. free_initrd_mem() is also moved to the __init section.

2011-06-09md: check ->hot_remove_disk when removing diskNamhyung Kim1-1/+1
Check pers->hot_remove_disk instead of pers->hot_add_disk in slot_store() during disk removal. The linear personality only has ->hot_add_disk and no ->hot_remove_disk, so that removing disk in the array resulted to following kernel bug: $ sudo mdadm --create /dev/md0 --level=linear --raid-devices=4 /dev/loop[0-3] $ echo none | sudo tee /sys/block/md0/md/dev-loop2/slot BUG: unable to handle kernel NULL pointer dereference at (null) IP: [< (null)>] (null) PGD c9f5d067 PUD 8575a067 PMD 0 Oops: 0010 [#1] SMP CPU 2 Modules linked in: linear loop bridge stp llc kvm_intel kvm asus_atk0110 sr_mod cdrom sg Pid: 10450, comm: tee Not tainted 3.0.0-rc1-leonard+ #173 System manufacturer System Product Name/P5G41TD-M PRO RIP: 0010:[<0000000000000000>] [< (null)>] (null) RSP: 0018:ffff880085757df0 EFLAGS: 00010282 RAX: ffffffffa00168e0 RBX: ffff8800d1431800 RCX: 000000000000006e RDX: 0000000000000001 RSI: 0000000000000002 RDI: ffff88008543c000 RBP: ffff880085757e48 R08: 0000000000000002 R09: 000000000000000a R10: 0000000000000000 R11: ffff88008543c2e0 R12: 00000000ffffffff R13: ffff8800b4641000 R14: 0000000000000005 R15: 0000000000000000 FS: 00007fe8c9e05700(0000) GS:ffff88011fa00000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b CR2: 0000000000000000 CR3: 00000000b4502000 CR4: 00000000000406e0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 Process tee (pid: 10450, threadinfo ffff880085756000, task ffff8800c9f08000) Stack: ffffffff8138496a ffff8800b4641000 ffff88008543c268 0000000000000000 ffff8800b4641000 ffff88008543c000 ffff8800d1431868 ffffffff81a78a90 ffff8800b4641000 ffff88008543c000 ffff8800d1431800 ffff880085757e98 Call Trace: [<ffffffff8138496a>] ? slot_store+0xaa/0x265 [<ffffffff81384bae>] rdev_attr_store+0x89/0xa8 [<ffffffff8115a96a>] sysfs_write_file+0x108/0x144 [<ffffffff81106b87>] vfs_write+0xb1/0x10d [<ffffffff8106e6c0>] ? trace_hardirqs_on_caller+0x111/0x135 [<ffffffff81106cac>] sys_write+0x4d/0x77 [<ffffffff814fe702>] system_call_fastpath+0x16/0x1b Code: Bad RIP value.
