2014-01-30Merge branch 'for-3.14/core' of git://git.kernel.dk/linux-blockLinus Torvalds
Pull core block IO changes from Jens Axboe: "The major piece in here is the immutable bio_ve series from Kent, the rest is fairly minor. It was supposed to go in last round, but various issues pushed it to this release instead. The pull request contains: - Various smaller blk-mq fixes from different folks. Nothing major here, just minor fixes and cleanups. - Fix for a memory leak in the error path in the block ioctl code from Christian Engelmayer. - Header export fix from CaiZhiyong. - Finally the immutable biovec changes from Kent Overstreet. This enables some nice future work on making arbitrarily sized bios possible, and splitting more efficient. Related fixes to immutable bio_vecs: - dm-cache immutable fixup from Mike Snitzer. - btrfs immutable fixup from Muthu Kumar. - bio-integrity fix from Nic Bellinger, which is also going to stable" * 'for-3.14/core' of git://git.kernel.dk/linux-block: (44 commits) xtensa: fixup simdisk driver to work with immutable bio_vecs block/blk-mq-cpu.c: use hotcpu_notifier() blk-mq: for_each_* macro correctness block: Fix memory leak in rw_copy_check_uvector() handling bio-integrity: Fix bio_integrity_verify segment start bug block: remove unrelated header files and export symbol blk-mq: uses page->list incorrectly blk-mq: use __smp_call_function_single directly btrfs: fix missing increment of bi_remaining Revert "block: Warn and free bio if bi_end_io is not set" block: Warn and free bio if bi_end_io is not set blk-mq: fix initializing request's start time block: blk-mq: don't export blk_mq_free_queue() block: blk-mq: make blk_sync_queue support mq block: blk-mq: support draining mq queue dm cache: increment bi_remaining when bi_end_io is restored block: fixup for generic bio chaining block: Really silence spurious compiler warnings block: Silence spurious compiler warnings block: Kill bio_pair_split() ...

2014-01-29s390/compat: change parameter types from unsigned long to compat_ulong_tHeiko Carstens
Change parameter types of s390's compat ipc syscall from unsigned long to compat_ulong_t to enforce zero extension of these parameters. This is not really a bug, since s390_ipc compat syscall is only a wrapper to the generic compat_sys_ipc() syscall, which performs correct zero and sign extension. This was introduced with commit 56e41d3c5aa8 ("merge compat sys_ipc instances").

2014-01-29sparc: Hook up sched_setattr and sched_getattr syscalls.David S. Miller
Signed-off-by: David S. Miller <davem@davemloft.net>
2014-01-28sparc: don't use module_init in non-modular pci.c codePaul Gortmaker
The pci.o is built for SPARC64_PCI -- which is bool, and hence this code is either present or absent. It will never be modular, so using module_init as an alias for __initcall can be somewhat misleading. Fix this up now, so that we can relocate module_init from init.h into module.h in the future. If we don't do this, we'd have to add module.h to obviously non-modular code, and that would be a worse thing. Note that direct use of __initcall is discouraged, vs. one of the priority categorized subgroups. As __initcall gets mapped onto device_initcall, our use of device_initcall directly in this change means that the runtime impact is zero -- it will remain at level 6 in initcall ordering.

2014-01-28ARM: 7941/2: Fix incorrect FDT initrd parameter overrideBen Peddell
Commit 65939301acdb (arm: set initrd_start/initrd_end for fdt scan) caused the FDT initrd_start and initrd_end to override the phys_initrd_start and phys_initrd_size set by the initrd= kernel parameter. With this patch initrd_start and initrd_end will be overridden if phys_initrd_start and phys_initrd_size are set by the kernel initrd= parameter.

2014-01-28ARM: 7930/1: Introduce atomic MMIO modifyEzequiel Garcia
Some SoC have MMIO regions that are shared across orthogonal subsystems. This commit implements a possible solution for the thread-safe access of such regions through a spinlock-protected API. Concurrent access is protected with a single spinlock for the entire MMIO address space. While this protects shared-registers, it also serializes access to unrelated/unshared registers. We add relaxed and non-relaxed variants, by using writel_relaxed and writel, respectively. The rationale for this is that some users may not require register write completion but only thread-safe access to a register.

git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc Pull powerpc mremap fix from Ben Herrenschmidt: "This is the patch that I had sent after -rc8 and which we decided to wait before merging. It's based on a different tree than my -next branch (it needs some pre-reqs that were in -rc4 or so while my -next is based on -rc1) so I left it as a separate branch for your to pull. It's identical to the request I did 2 or 3 weeks back. This fixes crashes in mremap with THP on powerpc. The fix however requires a small change in the generic code. It moves a condition into a helper we can override from the arch which is harmless, but it *also* slightly changes the order of the set_pmd and the withdraw & deposit, which should be fine according to Kirill (who wrote that code) but I agree -rc8 is a bit late... It was acked by Kirill and Andrew told me to just merge it via powerpc" * 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc: powerpc/thp: Fix crash on mremap

2014-01-27x86: revert wrong memblock current limit settingYinghai Lu
Dave reported big numa system booting is broken. It turns out that commit 5b6e529521d3 ("x86: memblock: set current limit to max low memory address") sets the limit to low wrongly. max_low_pfn_mapped is different from max_pfn_mapped. max_low_pfn_mapped is always under 4G. That will memblock_alloc_nid all go under 4G. Revert 5b6e529521d3 to fix a no-boot regression which was triggered by 457ff1de2d24 ("lib/swiotlb.c: use memblock apis for early memory allocations").

2014-01-28powerpc: Implement arch_spin_is_locked() using arch_spin_value_unlocked()Michael Ellerman
At a glance these are just the inverse of each other. The one subtlety is that arch_spin_value_unlocked() takes the lock by value, rather than as a pointer, which is important for the lockref code. On the other hand arch_spin_is_locked() doesn't really care, so implement it in terms of arch_spin_value_unlocked().

2014-01-28powerpc: Add support for the optimised lockref implementationMichael Ellerman
This commit adds the architecture support required to enable the optimised implementation of lockrefs. That's as simple as defining arch_spin_value_unlocked() and selecting the Kconfig option. We also define cmpxchg64_relaxed(), because the lockref code does not need the cmpxchg to have barrier semantics. Using Linus' test case[1] on one system I see a 4x improvement for the basic enablement, and a further 1.3x for cmpxchg64_relaxed(), for a total of 5.3x vs the baseline. On another system I see more like 2x improvement.
