* mm: re-architect the VM_UNPAGED logicLinus Torvalds2005-11-28
| | | | | | | | | | | | | | | | This replaces the (in my opinion horrible) VM_UNMAPPED logic with very explicit support for a "remapped page range" aka VM_PFNMAP. It allows a VM area to contain an arbitrary range of page table entries that the VM never touches, and never considers to be normal pages. Any user of "remap_pfn_range()" automatically gets this new functionality, and doesn't even have to mark the pages reserved or indeed mark them any other way. It just works. As a side effect, doing mmap() on /dev/mem works for arbitrary ranges. Sparc update from David in the next commit. Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* drm: fix quiescent lockingDave Airlie2005-11-24
| | | | | | | | | | | A fix for a locking bug which is triggered when a client tries to lock with flag DMA_QUIESCENT (typically the X server), but gets interrupted by a signal. The locking IOCTL should then return an error, but if DMA_QUIESCENT succeeds it returns 0, and the client falsely thinks it has the lock. In addition The client waits for DMA_QUISCENT and possibly DMA_READY without having the lock. From: Thomas Hellstrom Signed-off-by: Dave Airlie <airlied@linux.ie>
* drm: move is_pci to the end of the structureDave Airlie2005-11-23

* [PATCH] unpaged: ZERO_PAGE in VM_UNPAGEDHugh Dickins2005-11-22
| | | | | | | | | | | | | It's strange enough to be looking out for anonymous pages in VM_UNPAGED areas, let's not insert the ZERO_PAGE there - though whether it would matter will depend on what we decide about ZERO_PAGE refcounting. But whereas do_anonymous_page may (exceptionally) be called on a VM_UNPAGED area, do_no_page should never be: just BUG_ON.

For small allocations this isn't really seen, but when you start allocating 50000 pages of AGP space, for say, texture memory, then things can take seconds to complete. In some cases the situation is doubled or even quadrupled in the time due to SMP, or a deallocation, then a new reallocation. I've had a case of upto 20 seconds wait time to deallocate and reallocate AGP space. This patch fixes the problem by making it the caller's responsibility to call global_flush_tlb(), and so removes it from every instance of mapping a page into AGP space until the time that all change_page_attr() changes are done.
