2012-11-30[SCSI] sd: put to stopped power state when runtime suspendAaron Lu
When device is runtime suspended, put it to stopped power state to save some power. This will also make the behaviour consistent with what the scsi_pm.c thinks about sd as the comment says: sd treats runtime suspend, system suspend and system hibernate identical. With this patch, it is now identical. And sd_shutdown will also do nothing when it finds the device has been runtime suspended, if we do not spin down the disk in runtime suspend by putting it into stopped power state, the disk will be shut down incorrectly. And the the same problem can be solved for runtime power off after runtime suspended case by this change. With the current runtime scheme for disk, it will only be runtime suspended when no process opens the disk, so this shouldn't happen a lot, which makes it acceptable to spin down the disk when runtime suspended. If some day a more aggressive runtime scheme is used, like the 'request based runtime pm for disk' that Alan Stern and Lin Ming has been working, we can introduce some policy to control this. But for now, make it simple and correct by spinning down the disk. Signed-off-by: Aaron Lu <aaron.lu@intel.com> Acked-by: Alan Stern <stern@rowland.harvard.edu> Acked-by: Rafael J.

2012-11-30[SCSI] mvsas: fix undefined bit shiftXi Wang
The macro bit(n) is defined as ((u32)1 << n), and thus it doesn't work with n >= 32, such as in mvs_94xx_assign_reg_set(): if (i >= 32) { mvi->sata_reg_set |= bit(i); ... } The shift ((u32)1 << n) with n >= 32 also leads to undefined behavior. The result varies depending on the architecture. This patch changes bit(n) to do a 64-bit shift. It also simplifies mv_ffc64() using __ffs64(), since invoking ffz() with ~0 is undefined.

2012-11-30[SCSI] prevent stack buffer overflow in host_resetSasha Levin
store_host_reset() has tried to re-invent the wheel to compare sysfs strings. Unfortunately it did so poorly and never bothered to check the input from userspace before overwriting stack with it, so something simple as: echo "WoopsieWoopsie" > /sys/devices/pseudo_0/adapter0/host0/scsi_host/host0/host_reset would result in: [ 316.310101] Kernel panic - not syncing: stack-protector: Kernel stack is corrupted in: ffffffff81f5bac7 [ 316.310101] [ 316.320051] Pid: 6655, comm: sh Tainted: G W 3.7.0-rc5-next-20121114-sasha-00016-g5c9d68d-dirty #129 [ 316.320051] Call Trace: [ 316.340058] pps pps0: PPS event at 1352918752.620355751 [ 316.340062] pps pps0: capture assert seq #303 [ 316.320051] [<ffffffff83b3856b>] panic+0xcd/0x1f4 [ 316.320051] [<ffffffff81f5bac7>] ? store_host_reset+0xd7/0x100 [ 316.320051] [<ffffffff8110b996>] __stack_chk_fail+0x16/0x20 [ 316.320051] [<ffffffff81f5bac7>] store_host_reset+0xd7/0x100 [ 316.320051] [<ffffffff81e55bb3>] dev_attr_store+0x13/0x30 [ 316.320051] [<ffffffff812f7db1>] sysfs_write_file+0x101/0x170 [ 316.320051] [<ffffffff8127acc8>] vfs_write+0xb8/0x180 [ 316.320051] [<ffffffff8127ae80>] sys_write+0x50/0xa0 [ 316.320051] [<ffffffff83c03418>] tracesys+0xe1/0xe6 Fix this by uninventing whatever was going on there and just use sysfs_streq.

2012-11-29staging: comedi: addi_apci_2032: separate from addi_common.cH Hartley Sweeten
This driver is for a simple 32 channel digital output board. Using the addi-data "common" code introduces a lot of bloat. Copy the code in addi_common.c to this driver and remove the #include that caused addi_common.c to be compiled with this driver. This will allow removing the bloat. Rename the attach_pci and detach functions so they have namespace associated with this driver.

2012-11-29blkdev_max_block: make private to fs/buffer.cLinus Torvalds
We really don't want to look at the block size for the raw block device accesses in fs/block-dev.c, because it may be changing from under us. So get rid of the max_block logic entirely, since the caller should already have done it anyway. That leaves the only user of this function in fs/buffer.c, so move the whole function there and make it static. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2012-11-29KVM: Fix user memslot overlap checkAlex Williamson
Prior to memory slot sorting this loop compared all of the user memory slots for overlap with new entries. With memory slot sorting, we're just checking some number of entries in the array that may or may not be user slots. Instead, walk all the slots with kvm_for_each_memslot, which has the added benefit of terminating early when we hit the first empty slot, and skip comparison to private slots.

2012-11-29KVM: VMX: fix memory order between loading vmcs and clearing vmcsXiao Guangrong
vmcs->cpu indicates whether it exists on the target cpu, -1 means the vmcs does not exist on any vcpu If vcpu load vmcs with vmcs.cpu = -1, it can be directly added to cpu's percpu list. The list can be corrupted if the cpu prefetch the vmcs's list before reading vmcs->cpu. Meanwhile, we should remove vmcs from the list before making vmcs->vcpu == -1 be visible Signed-off-by: Xiao Guangrong <xiaoguangrong@linux.vnet.ibm.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
2012-11-29x86, 386 removal: Document Nx586 as a 386 and thus unsupportedH. Peter Anvin
Per Alan Cox, Nx586 did not support WP in supervisor mode, making it a 386 by Linux kernel standards. As such, it is too unsupported now.
