  • This patch introduces common.[ch] which are used only in the
    arch/arm/mach-exynos/ directory. The common.c file merges
    the cpu.c, init.c, irq-combiner.c and irq-eint.c files which
    are used commonly on EXYNOS SoCs and the common.h file replaces
    with plat/exynos4.h file.

  • This silently was working for many years and stopped working on
    Niagara-T3 machines.

    We need to set the MSIQ to VALID before we can set it's state to IDLE.

    On Niagara-T3, setting the state to IDLE first was causing HV_EINVAL
    errors. The hypervisor documentation says, rather ambiguously, that
    the MSIQ must be "initialized" before one can set the state.

    I previously understood this to mean merely that a successful setconf()
    operation has been performed on the MSIQ, which we have done at this
    point. But it seems to also mean that it has been set VALID too.

  • When printing the code bytes in show_registers(), the markers around the
    byte at the fault address could make the printk() format string look
    like a valid log level and facility code. This would prevent this byte
    from being printed and result in a spurious newline:

    Add KERN_CONT where needed, and elsewhere in show_registers() for
    consistency.

  • x86 jump instruction size is 2 or 5 bytes (near/long jump), not 2 or 6
    bytes.

    In case a conditional jump is followed by a long jump, conditional jump
    target is one byte past the start of target instruction.

  • If oprofilefs_ulong_from_user() is called with count equals
    zero, *val remains unchanged. Depending on the implementation it
    might be uninitialized.

    Change oprofilefs_ulong_from_user()'s interface to return count
    on success. Thus, we are able to return early if count equals
    zero which avoids using *val uninitialized. Fixing all users of
    oprofilefs_ulong_ from_user().

    This follows write syscall implementation when count is zero:
    "If count is zero ... [and if] no errors are detected, 0 will be
    returned without causing any other effect." (man 2 write)

    xen/swiotlb: Use page alignment for early buffer allocation.
    xen: only limit memory map to maximum reservation for domain 0.

    Linus Torvalds
     
  • d312ae878b6a "xen: use maximum reservation to limit amount of usable RAM"
    clamped the total amount of RAM to the current maximum reservation. This is
    correct for dom0 but is not correct for guest domains. In order to boot a guest
    "pre-ballooned" (e.g. with memory=1G but maxmem=2G) in order to allow for
    future memory expansion the guest must derive max_pfn from the e820 provided by
    the toolstack and not the current maximum reservation (which can reflect only
    the current maximum, not the guest lifetime max). The existing algorithm
    already behaves this correctly if we do not artificially limit the maximum
    number of pages for the guest case.

    For a guest booted with maxmem=512, memory=128 this results in:

  • efi_call_phys_prelog() sets up a 1:1 mapping of the physical address
    range in swapper_pg_dir. Instead of replacing then restoring entries
    in swapper_pg_dir we should be using initial_page_table which already
    contains the 1:1 mapping.

    It's safe to blindly switch back to swapper_pg_dir in the epilog
    because the physical EFI routines are only called before
    efi_enter_virtual_mode(), e.g. before any user processes have been
    forked. Therefore, we don't need to track which pgd was in %cr3 when
    we entered the prelog.

    The previous code actually contained a bug because it assumed that the
    kernel was loaded at a physical address within the first 8MB of ram,
    usually at 0x100000. However, this isn't the case with a
    CONFIG_RELOCATABLE=y kernel which could have been loaded anywhere in
    the physical address space.

    Also delete the ancient (and bogus) comments about the page table
    being restored after the lock is released. There is no locking.
