Making the IPv4 assumption explicit by settting default_dst protocol family to AF_INET4 and preventing mixing of IPv4 and IPv6 addresses in snooped fdb entries fixes the corner case crashes.

2014-04-03s390/uaccess: rework uaccess code - fix locking issuesHeiko Carstens
The current uaccess code uses a page table walk in some circumstances, e.g. in case of the in atomic futex operations or if running on old hardware which doesn't support the mvcos instruction. However it turned out that the page table walk code does not correctly lock page tables when accessing page table entries. In other words: a different cpu may invalidate a page table entry while the current cpu inspects the pte. This may lead to random data corruption. Adding correct locking however isn't trivial for all uaccess operations. Especially copy_in_user() is problematic since that requires to hold at least two locks, but must be protected against ABBA deadlock when a different cpu also performs a copy_in_user() operation. So the solution is a different approach where we change address spaces: User space runs in primary address mode, or access register mode within vdso code, like it currently already does. The kernel usually also runs in home space mode, however when accessing user space the kernel switches to primary or secondary address mode if the mvcos instruction is not available or if a compare-and-swap (futex) instruction on a user space address is performed. KVM however is special, since that requires the kernel to run in home address space while implicitly accessing user space with the sie instruction. So we end up with: User space: - runs in primary or access register mode - cr1 contains the user asce - cr7 contains the user asce - cr13 contains the kernel asce Kernel space: - runs in home space mode - cr1 contains the user or kernel asce -> the kernel asce is loaded when a uaccess requires primary or secondary address mode - cr7 contains the user or kernel asce, (changed with set_fs()) - cr13 contains the kernel asce In case of uaccess the kernel changes to: - primary space mode in case of a uaccess (copy_to_user) and uses e.g. the mvcp instruction to access user space. However the kernel will stay in home space mode if the mvcos instruction is available - secondary space mode in case of futex atomic operations, so that the instructions come from primary address space and data from secondary space In case of kvm the kernel runs in home space mode, but cr1 gets switched to contain the gmap asce before the sie instruction gets executed. When the sie instruction is finished cr1 will be switched back to contain the user asce. A context switch between two processes will always load the kernel asce for the next process in cr1. So the first exit to user space is a bit more expensive (one extra load control register instruction) than before, however keeps the code rather simple. In sum this means there is no need to perform any error prone page table walks anymore when accessing user space. The patch seems to be rather large, however it mainly removes the the page table walk code and restores the previously deleted "standard" uaccess code, with a couple of changes. The uaccess without mvcos mode can be enforced with the "uaccess_primary" kernel parameter.

2014-04-03s390/mm,tlb: optimize TLB flushing for zEC12Martin Schwidefsky
The zEC12 machines introduced the local-clearing control for the IDTE and IPTE instruction. If the control is set only the TLB of the local CPU is cleared of entries, either all entries of a single address space for IDTE, or the entry for a single page-table entry for IPTE. Without the local-clearing control the TLB flush is broadcasted to all CPUs in the configuration, which is expensive. The reset of the bit mask of the CPUs that need flushing after a non-local IDTE is tricky. As TLB entries for an address space remain in the TLB even if the address space is detached a new bit field is required to keep track of attached CPUs vs. CPUs in the need of a flush. After a non-local flush with IDTE the bit-field of attached CPUs is copied to the bit-field of CPUs in need of a flush. The ordering of operations on cpu_attach_mask, attach_count and mm_cpumask(mm) is such that an underindication in mm_cpumask(mm) is prevented but an overindication in mm_cpumask(mm) is possible. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
2014-04-03s390/mm,tlb: safeguard against speculative TLB creationMartin Schwidefsky
The principles of operations states that the CPU is allowed to create TLB entries for an address space anytime while an ASCE is loaded to the control register. This is true even if the CPU is running in the kernel and the user address space is not (actively) accessed. In theory this can affect two aspects of the TLB flush logic. For full-mm flushes the ASCE of the dying process is still attached. The approach to flush first with IDTE and then just free all page tables can in theory lead to stale TLB entries. Use the batched free of page tables for the full-mm flushes as well. For operations that can have a stale ASCE in the control register, e.g. a delayed update_user_asce in switch_mm, load the kernel ASCE to prevent invalid TLBs from being created.

2014-04-03ALSA: hda - Fix silent speaker output due to mute LED fixupTakashi Iwai
The recent fixups for HP laptops to support the mute LED made the speaker output silent on some machines. It turned out that they use the NID 0x18 for the speaker while it's also used for controlling the LED via VREF bits although the current driver code blindly assumes that such a node is a mic pin (where 0x18 is usually so). This patch fixes the problem by only changing the VREF bits and keeping the other pin ctl bits.

2014-04-03arm64: Update the TCR_EL1 translation granule definitions for 16K pagesCatalin Marinas
The current TCR register setting in arch/arm64/mm/proc.S assumes that TCR_EL1.TG* fields are one bit wide and bit 31 is RES1 (reserved, set to 1). With the addition of 16K pages (currently unsupported in the kernel), the TCR_EL1.TG* fields have been extended to two bits. This patch updates the corresponding Linux definitions and drops the bit 31 setting in proc.S in favour of the new macros.
