2018-10-04ACPICA: Update for generic_serial_bus and attrib_raw_process_bytes protocolBob Moore
Cleanup for this write-then-read protocol. The ACPI specification is rather unclear for the entire generic_serial_bus, but this change works correctly on the Surface 3.

This patch moves hfi1_copy_sge() into rdmavt for sharing with qib. This patch also moves all the wss_*() functions into rdmavt as several wss_*() functions are called from hfi1_copy_sge() When SGE copy mode is adaptive, cacheless copy may be done in some cases for performance reasons. In those cases, X86 cacheless copy function is called since the drivers that use rdmavt and may set SGE copy mode to adaptive are X86 only.

2018-10-03signal: Use a smaller struct siginfo in the kernelEric W. Biederman
We reserve 128 bytes for struct siginfo but only use about 48 bytes on 64bit and 32 bytes on 32bit. Someday we might use more but it is unlikely to be anytime soon. Userspace seems content with just enough bytes of siginfo to implement sigqueue. Or in the case of checkpoint/restart reinjecting signals the kernel has sent. Reducing the stack footprint and the work to copy siginfo around from 2 cachelines to 1 cachelines seems worth doing even if I don't have benchmarks to show a performance difference.

2018-10-03signal: Distinguish between kernel_siginfo and siginfoEric W. Biederman
Linus recently observed that if we did not worry about the padding member in struct siginfo it is only about 48 bytes, and 48 bytes is much nicer than 128 bytes for allocating on the stack and copying around in the kernel. The obvious thing of only adding the padding when userspace is including siginfo.h won't work as there are sigframe definitions in the kernel that embed struct siginfo. So split siginfo in two; kernel_siginfo and siginfo. Keeping the traditional name for the userspace definition. While the version that is used internally to the kernel and ultimately will not be padded to 128 bytes is called kernel_siginfo. The definition of struct kernel_siginfo I have put in include/signal_types.h A set of buildtime checks has been added to verify the two structures have the same field offsets. To make it easy to verify the change kernel_siginfo retains the same size as siginfo. The reduction in size comes in a following change. Signed-off-by: "Eric W. Biederman" <ebiederm@xmission.com>
2018-10-03signal: Introduce copy_siginfo_from_user and use it's return valueEric W. Biederman
In preparation for using a smaller version of siginfo in the kernel introduce copy_siginfo_from_user and use it when siginfo is copied from userspace. Make the pattern for using copy_siginfo_from_user and copy_siginfo_from_user32 to capture the return value and return that value on error. This is a necessary prerequisite for using a smaller siginfo in the kernel than the kernel exports to userspace. Signed-off-by: "Eric W. Biederman" <ebiederm@xmission.com>

2018-10-03kvm: arm64: Allow tuning the physical address size for VMSuzuki K Poulose
Allow specifying the physical address size limit for a new VM via the kvm_type argument for the KVM_CREATE_VM ioctl. This allows us to finalise the stage2 page table as early as possible and hence perform the right checks on the memory slots without complication. The size is encoded as Log2(PA_Size) in bits[7:0] of the type field. For backward compatibility the value 0 is reserved and implies 40bits. Also, lift the limit of the IPA to host limit and allow lower IPA sizes (e.g, 32). The userspace could check the extension KVM_CAP_ARM_VM_IPA_SIZE for the availability of this feature. The cap check returns the maximum limit for the physical address shift supported by the host.

2018-10-03media: v4l: event: Prevent freeing event subscriptions while accessedSakari Ailus
The event subscriptions are added to the subscribed event list while holding a spinlock, but that lock is subsequently released while still accessing the subscription object. This makes it possible to unsubscribe the event --- and freeing the subscription object's memory --- while the subscription object is simultaneously accessed. Prevent this by adding a mutex to serialise the event subscription and unsubscription. This also gives a guarantee to the callback ops that the add op has returned before the del op is called. This change also results in making the elems field less special: subscriptions are only added to the event list once they are fully initialised.

2018-10-03netfilter: xt_quota: fix the behavior of xt_quota moduleChenbo Feng
A major flaw of the current xt_quota module is that quota in a specific rule gets reset every time there is a rule change in the same table. It makes the xt_quota module not very useful in a table in which iptables rules are changed at run time. This fix introduces a new counter that is visible to userspace as the remaining quota of the current rule. When userspace restores the rules in a table, it can restore the counter to the remaining quota instead of resetting it to the full quota.

2018-10-03mtd: rawnand: Allow selection of ECC byte ordering at runtimeBoris Brezillon
Currently, the selection of ECC byte ordering for software hamming is done at compilation time, which doesn't make sense when ECC byte calculation is done in hardware and byte ordering is forced by the hardware engine. In this case, only the correction is done in software and we want to force the byte-ordering no matter the value of CONFIG_MTD_NAND_ECC_SMC. This is typically the case for the FSMC (Smart Media ordering), TMIO and TXX9NDFMC (regular byte ordering) blocks. For all other use cases (pure software implementation, SM FTL and nandecctest), we keep selecting the byte ordering based on the CONFIG_MTD_NAND_ECC_SMC value. It might not be ideal for SM FTL (I'd expect Smart Media ordering to be employed by the Smart Media FTL), but this option doesn't seem to be enabled in the existing _defconfig, so I can't tell setting sm_order to true is the right choice.

nand_scan[with_ids]() have been moved at the end of the file. We can now get rid of of the nand_flash_dev forward declaration. Signed-off-by: Boris Brezillon <boris.brezillon@bootlin.com> Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com>
2018-10-03mtd: rawnand: Move function prototypes after struct declarationsBoris Brezillon
Move nand_scan[_with_ids]() and nand_wait_ready() at the end of the file where all function prototype lies. This will also allow us to get rid of the nand_flash_dev forward declaration.

2018-10-03mtd: rawnand: Deprecate ->chip_delayBoris Brezillon
The wait timeouts and delays are directly extracted from the NAND timings and ->chip_delay is only used in legacy path, so let's move it to the nand_legacy struct to make it clear. Signed-off-by: Boris Brezillon <boris.brezillon@bootlin.com> Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com>
2018-10-03mtd: rawnand: Deprecate ->{set,get}_features() hooksBoris Brezillon
Those hooks should be replaced by a proper ->exec_op() implementation. Move them to the nand_legacy struct to make it clear. Signed-off-by: Boris Brezillon <boris.brezillon@bootlin.com> Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com>
