2013-11-28md/raid5: fix newly-broken locking in get_active_stripe.NeilBrown
commit 566c09c53455d7c4f1 raid5: relieve lock contention in get_active_stripe() modified the locking in get_active_stripe() reducing the range protected by the (highly contended) device_lock. Unfortunately it reduced the range too much opening up some races. One race can occur if get_priority_stripe runs between the test on sh->count and device_lock being taken. This will mean that sh->lru is not empty while get_active_stripe thinks ->count is zero resulting in a 'BUG' firing. Another race happens if __release_stripe is called immediately after sh->count is tested and found to be non-zero. If STRIPE_HANDLE is not set, get_active_stripe should increment ->active_stripes when it increments ->count from 0, but as it didn't think it was 0, it doesn't. Extending device_lock to cover the test on sh->count close these races. While we are here, fix the two BUG tests: -If count is zero, then lru really must not be empty, or we've lock the stripe_head somehow - no other tests are relevant. -STRIPE_ON_RELEASE_LIST is completely independent of ->lru so testing it is pointless.

Now, after commit bcdde7e221a8, the sysfs directory is removed along with all of its subdirectories that include the SCSI host's sysfs directory and its subdirectories at this point. Consequently, when device_del() is finally called for any child device of the SCSI host and tries to remove its "power" group (which is already gone then), it triggers the above warning. To make the warnings go away, change the removal ordering in ata_port_detach() so that the SCSI host is removed from the port before ata_tport_delete() is called.

All OMAP IP blocks expect LE data, but CPU may operate in BE mode. Need to use endian neutral functions to read/write h/w registers. I.e instead of __raw_read[lw] and __raw_write[lw] functions code need to use read[lw]_relaxed and write[lw]_relaxed functions. If the first simply reads/writes register, the second will byteswap it if host operates in BE mode. Changes are trivial sed like replacement of __raw_xxx functions with xxx_relaxed variant.

2013-11-27gpio: pl061: move irqdomain initializationLinus Walleij
The PL061 driver had the irqdomain initialization in an unfortunate place: when used with device tree (and thus passing the base IRQ 0) the driver would work, as this registers an irqdomain and waits for mappings to be done dynamically as the devices request their IRQs, whereas when booting using platform data the irqdomain core would attempt to allocate IRQ descriptors dynamically (which works fine) but also to associate the irq_domain_associate_many() on all IRQs, which in turn will call the mapping function which at this point will try to set the type of the IRQ and then tries to acquire a non-initialized spinlock yielding a backtrace like this: CPU: 0 PID: 1 Comm: swapper Not tainted 3.13.0-rc1+ #652 Backtrace: [<c0016f0c>] (dump_backtrace) from [<c00172ac>] (show_stack+0x18/0x1c) r6:c798ace0 r5:00000000 r4:c78257e0 r3:00200140 [<c0017294>] (show_stack) from [<c0329ea0>] (dump_stack+0x20/0x28) [<c0329e80>] (dump_stack) from [<c004fa80>] (__lock_acquire+0x1c0/0x1b80) [<c004f8c0>] (__lock_acquire) from [<c0051970>] (lock_acquire+0x6c/0x80) r10:00000000 r9:c0455234 r8:00000060 r7:c047d798 r6:600000d3 r5:00000000 r4:c782c000 [<c0051904>] (lock_acquire) from [<c032e484>] (_raw_spin_lock_irqsave+0x60/0x74) r6:c01a1100 r5:800000d3 r4:c798acd0 [<c032e424>] (_raw_spin_lock_irqsave) from [<c01a1100>] (pl061_irq_type+0x28/0x) r6:00000000 r5:00000000 r4:c798acd0 [<c01a10d8>] (pl061_irq_type) from [<c0059ef4>] (__irq_set_trigger+0x70/0x104) r6:00000000 r5:c01a10d8 r4:c046da1c r3:c01a10d8 [<c0059e84>] (__irq_set_trigger) from [<c005b348>] (irq_set_irq_type+0x40/0x60) r10:c043240c r8:00000060 r7:00000000 r6:c046da1c r5:00000060 r4:00000000 [<c005b308>] (irq_set_irq_type) from [<c01a1208>] (pl061_irq_map+0x40/0x54) r6:c79693c0 r5:c798acd0 r4:00000060 [<c01a11c8>] (pl061_irq_map) from [<c005d27c>] (irq_domain_associate+0xc0/0x190) r5:00000060 r4:c046da1c [<c005d1bc>] (irq_domain_associate) from [<c005d604>] (irq_domain_associate_man) r8:00000008 r7:00000000 r6:c79693c0 r5:00000060 r4:00000000 [<c005d5d0>] (irq_domain_associate_many) from [<c005d864>] (irq_domain_add_simp) r8:c046578c r7:c035b72c r6:c79693c0 r5:00000060 r4:00000008 r3:00000008 [<c005d814>] (irq_domain_add_simple) from [<c01a1380>] (pl061_probe+0xc4/0x22c) r6:00000060 r5:c0464380 r4:c798acd0 [<c01a12bc>] (pl061_probe) from [<c01c0450>] (amba_probe+0x74/0xe0) r10:c043240c r9:c0455234 r8:00000000 r7:c047d7f8 r6:c047d744 r5:00000000 r4:c0464380 This moves the irqdomain initialization to a point where the spinlock and GPIO chip are both fully propulated, so the callbacks can be used without crashes. I had some problem reproducing the crash, as the devm_kzalloc():ed zeroed memory would seemingly mask the spinlock as something OK, but by poisoning the lock like this: u32 *dum; dum = (u32 *) &chip->lock; *dum = 0xaaaaaaaaU; I could reproduce, fix and test the patch.

UHID allows short writes so user-space can omit unused fields. We automatically set them to 0 in the kernel. However, the 64/32 bit compat-handler didn't do that in the UHID_CREATE fallback.

I2C IP block expect LE data, but CPU may operate in BE mode. Need to use endian neutral functions to read/write h/w registers. I.e instead of __raw_read[lw] and __raw_write[lw] functions code need to use read[lw]_relaxed and write[lw]_relaxed functions. If the first simply reads/writes register, the second will byteswap it if host operates in BE mode. Changes are trivial sed like replacement of __raw_xxx functions with xxx_relaxed variant.

2013-11-25staging: zsmalloc: Ensure handle is never 0 on successOlav Haugan
zsmalloc encodes a handle using the pfn and an object index. On hardware platforms with physical memory starting at 0x0 the pfn can be 0. This causes the encoded handle to be 0 and is incorrectly interpreted as an allocation failure. This issue affects all current and future SoCs with physical memory starting at 0x0. All MSM8974 SoCs which includes Google Nexus 5 devices are affected. To prevent this false error we ensure that the encoded handle will not be 0 when allocation succeeds.

We had a round of clearing this out some time ago but this driver clearly slipped through. * A misuse of the IIO_ST macro, in mcp3422, which we should really make a concertive effort to finish removing. * Avoid a double free introduced by recent buffer reference counting in the one driver that (quite reasonably!) does things differently (am335x) * A missing mutex_unlock in kxsd9 that means that driver has been non functional for some time and no one noticed (including me who for once actually has one of the supported devices). * An incorrect assumption about the parameters of sign_extend32 in mcp3422. So nothing controversial. The only substantial patch is the hid_sensors one and that is actually just adding a new pointer to the devices private state then moving the code over to it.
