  • b845f313d   mm: Allow architectures to define additional protection bits ... Browse Code »

    This patch allows architectures to define functions to deal with
    additional protections bits for mmap() and mprotect().

    arch_calc_vm_prot_bits() maps additonal protection bits to vm_flags
    arch_vm_get_page_prot() maps additional vm_flags to the vma's vm_page_prot
    arch_validate_prot() checks for valid values of the protection bits

    Note: vm_get_page_prot() is now pretty ugly, but the generated code
    should be identical for architectures that don't define additional
    protection bits.

  • 80119ef5c   mm: fix atomic_t overflow in vm ... Browse Code »

    The atomic_t type is 32bit but a 64bit system can have more than 2^32
    pages of virtual address space available. Without this we overflow on
    ludicrously large mappings

    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!
