* mm: Allow architectures to define additional protection bitsDave Kleikamp2008-07-091-1/+28
| | | | | | | | | | | | | | | | | | 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.

* mm: fix atomic_t overflow in vmAlan Cox2008-05-241-2/+2
| | | | | | | | | | 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 Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* Sanitise linux/mman.h for userspace consumptionDavid Woodhouse2006-04-251-5/+8
| | | | | | | It only really needs to define a few constants and include <asm/mman.h> when it's used by userspace. Move the rest within #ifdef __KERNEL__ Signed-off-by: David Woodhouse <dwmw2@infradead.org>

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!
