    sg: disable interrupts inside sg_copy_buffer

  • Change the MN10300 fault handler to make it check in_atomic() rather than
    in_interrupt() as commit 6edaf68a87d17570790fd55f0c451a29ec1d6703 did for other
    architectures:

    [PATCH] mm: arch do_page_fault() vs in_atomic()

    In light of the recent pagefault and filemap_copy_from_user work I've
    gone through all the arch pagefault handlers to make sure the
    inc_preempt_count() 'feature' works as expected.

    Several sections of code (including the new filemap_copy_from_user)
    rely on the fact that faults do not take locks under increased preempt
    count.

  • The callers of sg_copy_buffer must disable interrupts before calling
    it (since it uses kmap_atomic). Some callers use it on
    interrupt-disabled code but some need to take the trouble to disable
    interrupts just for this. No wonder they forget about it and we hit a
    bug like:

    http://bugzilla.kernel.org/show_bug.cgi?id=11529

    James said that it might be better to disable interrupts inside the
    function rather than risk the callers getting it wrong.

  • Accesses to CR4 are intercepted even with Nested Paging enabled. But the code
    does not check if the guest wants to do a global TLB flush. So this flush gets
    lost. This patch adds the check and the flush to svm_set_cr4.

  • This patch introduces a guest TLB flush on every NPF exit in KVM. This fixes
    random segfaults and #UD exceptions in the guest seen under some workloads
    (e.g. long running compile workloads or tbench). A kernbench run with and
    without that fix showed that it has a slowdown lower than 0.5%

  • This fixes a SWIOTLB oops

    With SWIOTLB being enabled and straight-forward page allocation
    failure [1], the swiotlb_alloc_coherent fall-back path hits an
    issue [2], resulting in my webcam failing to work.

    At the time of oops, RDI is clearly a pointer to a structure which
    has arrived as NULL, leading to the typo in swiotlb_map_single's
    callsite arguments.

    Correctly passing the device structure [3] addresses the issue and
    gets my webcam working again (the allocation failure still occuring).

  • git commit 74811f355f4f69a187fa74892dcf2a684b84ce99 causes crash at
    module load (or boot) time on my machine with a hpt374 controller.
    The reason for this is that for initializing second controller which sets
    (hwif->dev == host->dev[1]) to true (1), adds 1 to a void ptr, which
    advances it by one byte instead of advancing it by sizeof(hpt_info) bytes.
    Because of this, all initialization functions get corrupted data in info
    variable which causes a crash at boot time.

    This patch fixes that and makes my machine boot again.

  • ocfs2 will become read-only if we try to read the bytes which pass
    the end of i_size. This can be easily reproduced by following steps:
    1. mkfs a ocfs2 volume with bs=4k cs=4k and nosparse.
    2. create a small file(say less than 100 bytes) and we will create the file
    which is allocated 1 cluster.
    3. read 8196 bytes from the kernel using O_DIRECT which exceeds the limit.
    4. The ocfs2 volume becomes read-only and dmesg shows:
    OCFS2: ERROR (device sda13): ocfs2_direct_IO_get_blocks:
    Inode 66010 has a hole at block 1
    File system is now read-only due to the potential of on-disk corruption.
    Please run fsck.ocfs2 once the file system is unmounted.

    So suppress the ERROR message.

  • This fixes kernel bugzilla 11469: "TUN with 1024 neighbours:
    ip6_dst_lookup_tail NULL crash"

    dst->neighbour is not necessarily hooked up at this point
    in the processing path, so blindly dereferencing it is
    the wrong thing to do. This NULL check exists in other
    similar paths and this case was just an oversight.

    Also fix the completely wrong and confusing indentation
    here while we're at it.

    Based upon a patch by Evgeniy Polyakov.

    clockevents: remove WARN_ON which was used to gather information

    Linus Torvalds
     
  • The issue of the endless reprogramming loop due to a too small
    min_delta_ns was fixed with the previous updates of the clock events
    code, but we had no information about the spread of this problem. I
    added a WARN_ON to get automated information via kerneloops.org and to
    get some direct reports, which allowed me to analyse the affected
    machines.

    The WARN_ON has served its purpose and would be annoying for a release
    kernel. Remove it and just keep the information about the increase of
    the min_delta_ns value.

  • When using kdump modifying the e820 map is yielding strange results.

    For example starting with

    BIOS-provided physical RAM map:
    BIOS-e820: 0000000000000100 - 0000000000093400 (usable)
    BIOS-e820: 0000000000093400 - 00000000000a0000 (reserved)
    BIOS-e820: 0000000000100000 - 000000003fee0000 (usable)
    BIOS-e820: 000000003fee0000 - 000000003fef3000 (ACPI data)
    BIOS-e820: 000000003fef3000 - 000000003ff80000 (ACPI NVS)
    BIOS-e820: 000000003ff80000 - 0000000040000000 (reserved)
    BIOS-e820: 00000000e0000000 - 00000000f0000000 (reserved)
    BIOS-e820: 00000000fec00000 - 00000000fec10000 (reserved)
    BIOS-e820: 00000000fee00000 - 00000000fee01000 (reserved)
    BIOS-e820: 00000000ff000000 - 0000000100000000 (reserved)

    and booting with args

    memmap=exactmap memmap=640K@0K memmap=5228K@16384K memmap=125188K@22252K memmap=76K#1047424K memmap=564K#1047500K

    resulted in:

    user-defined physical RAM map:
    user: 0000000000000000 - 0000000000093400 (usable)
    user: 0000000000093400 - 00000000000a0000 (reserved)
    user: 0000000000100000 - 000000003fee0000 (usable)
    user: 000000003fee0000 - 000000003fef3000 (ACPI data)
    user: 000000003fef3000 - 000000003ff80000 (ACPI NVS)
    user: 000000003ff80000 - 0000000040000000 (reserved)
    user: 00000000e0000000 - 00000000f0000000 (reserved)
    user: 00000000fec00000 - 00000000fec10000 (reserved)
    user: 00000000fee00000 - 00000000fee01000 (reserved)
    user: 00000000ff000000 - 0000000100000000 (reserved)

    But should have resulted in:

    user-defined physical RAM map:
    user: 0000000000000000 - 00000000000a0000 (usable)
    user: 0000000001000000 - 000000000151b000 (usable)
    user: 00000000015bb000 - 0000000008ffc000 (usable)
    user: 000000003fee0000 - 000000003ff80000 (ACPI data)

    This is happening because of an improper usage of strcmp() in the
    e820 parsing code. The strcmp() always returns !0 and never resets the
    value for e820.nr_map and returns an incorrect user-defined map.

    This patch fixes the problem.

  • It was introduced by "vsprintf: add support for '%pS' and '%pF' pointer
    formats" in commit 0fe1ef24f7bd0020f29ffe287dfdb9ead33ca0b2. However,
    the current way its coded doesn't work on parisc64. For two reasons: 1)
    parisc isn't in the #ifdef and 2) parisc has a different format for
    function descriptors

    Make dereference_function_descriptor() more accommodating by allowing
    architecture overrides. I put the three overrides (for parisc64, ppc64
    and ia64) in arch/kernel/module.c because that's where the kernel
    internal linker which knows how to deal with function descriptors sits.

  • When disconnected ccw devices are removed, the device has to be set
    offline, otherwise there will be side effects including a reference
    count imbalance. This patch modifies ccw_device_offline to work for
    devices in disconnecte/not operational state. ccw_device_offline is
    called by cio for devices which are online during device removal.
