    cputime_to_timeval() takes a struct timeval *as its second argument but
    a struct compat_timeval * will be passed resulting in:

  • 9843b030c   KVM/MIPS32: KVM Guest kernel support. ... Browse Code »

    Both Guest kernel and Guest Userspace execute in UM. The memory map is as follows:
    Guest User address space: 0x00000000 -> 0x40000000
    Guest Kernel Unmapped: 0x40000000 -> 0x60000000
    Guest Kernel Mapped: 0x60000000 -> 0x80000000
    - Guest Usermode virtual memory is limited to 1GB.

    Having received another series of whitespace patches I decided to do this
    once and for all rather than dealing with this kind of patches trickling
    in forever.

  • cad9bc690   MIPS: 64-bit: Fix o32 core dump ... Browse Code »

    If an o32 process generates a core dump on a 64 bit kernel, the core file
    will not be correctly recognized. This is because ELF_CORE_COPY_REGS and
    ELF_CORE_COPY_TASK_REGS are not correctly defined for o32 and will use
    the default register set which would be CONFIG_64BIT in asm/elf.h.

    So we'll switch to use the right register defines in this situation by
    checking for WANT_COMPAT_REG_H and use the right defines of
    ELF_CORE_COPY_REGS and ELF_CORE_COPY_TASK_REGS.

    [Ralf: made ELF_CORE_COPY_TASK_REGS() bullet-proof against funny arguments.]

  • f8bd2258e   remove div_long_long_rem ... Browse Code »

    x86 is the only arch right now, which provides an optimized for
    div_long_long_rem and it has the downside that one has to be very careful that
    the divide doesn't overflow.

    The API is a little akward, as the arguments for the unsigned divide are
    signed. The signed version also doesn't handle a negative divisor and
    produces worse code on 64bit archs.

    There is little incentive to keep this API alive, so this converts the few
    users to the new API.

    Define elf_addr_t in linux/elf.h. The size of the type is determined using

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
