| * [ARM SMP] Use event instructions for spinlocksRussell King2005-12-01
| | | | | | | | | | | | | | | | | | | | | | | | | | ARMv6K CPUs have SEV (send event) and WFE (wait for event) instructions which allow the CPU clock to be suspended until another CPU issues a SEV, rather than spinning on the lock wasting power. Make use of these instructions. Note that WFE does not wait if an event has been sent since the last WFE cleared the event status, so although it may look racy, the instruction implementation ensures that these are dealt with.

* | VM: add "vm_insert_page()" functionLinus Torvalds2005-11-30
| | | | | | | | | | | | | | | | | | | | | | | | | | This is what a lot of drivers will actually want to use to insert individual pages into a user VMA. It doesn't have the old PageReserved restrictions of remap_pfn_range(), and it doesn't complain about partial remappings. The page you insert needs to be a nice clean kernel allocation, so you can't insert arbitrary page mappings with this, but that's not what people want.

* [PATCH] process events connector: uid_t gid_t size issuesMatt Helsley2005-11-29
| | | | | | | | | | | | | | The uid_t and gid_t fields appear to present a 32/64-bit userspace/kernel problem for some archs. This patch addresses the problem by fixing the size to the largest size for uid_t/gid_t used in the kernel. This preserves the total size of the event structure while ensuring that the layouts of the ID change event match in 32 and 64-bit kernels and applications.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | Recent models of Intel/Sharp and Spansion CFI flash now have significant bits in the upper byte of device ID codes, read via what Spansion calls "autoselect" and Intel calls "read device identifier". Currently these values are truncated to the low 8 bits in the mtd data structures, as all CFI read query info has previously been read one byte at a time. Add a new method for reading 16-bit info, currently just manufacturer and device codes; datasheets hint at future uses for upper bytes in other fields.

* / Support strange discontiguous PFN remappingsLinus Torvalds2005-11-29
|/ | | | | | | | | | | | | These get created by some drivers that don't generally even want a pfn remapping at all, but would really mostly prefer to just map pages they've allocated individually instead. For now, create a helper function that turns such an incomplete PFN remapping call into a loop that does that explicit mapping. In the long run we almost certainly want to export a totally different interface for that, though. Signed-off-by: Linus Torvalds <torvalds@osdl.org>

* | | [PATCH] temporarily disable swap token on memory pressureRik van Riel2005-11-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some users (hi Zwane) have seen a problem when running a workload that eats nearly all of physical memory - th system does an OOM kill, even when there is still a lot of swap free. The problem appears to be a very big task that is holding the swap token, and the VM has a very hard time finding any other page in the system that is swappable. Instead of ignoring the swap token when sc->priority reaches 0, we could simply take the swap token away from the memory hog and make sure we don't give it back to the memory hog for a few seconds.

It deals with the following problems: (1) SEM_DEBUG should be SEMAPHORE_DEBUG. (2) The argument list to pcibios_penalize_isa_irq() has changed. (3) CONFIG_HIGHMEM can't be used directly in #if as it may not be defined. (4) page->private is no longer directly accessible. (5) linux/hardirq.h assumes asm/hardirq.h will include linux/irq.h (6) The IDE MMIO access functions are given pointers, not integers, and so get type casting errors. (7) __pa() is passed an explicit u64 type in drivers/char/mem.c, but that can't be cast directly to a pointer on a 32-bit platform. (8) SEMAPHORE_DEBUG should not be contingent on WAITQUEUE_DEBUG as that no longer exists. (9) PREEMPT_ACTIVE is too low a value.

The lock is already held during cpu_up() and cpu_down() calls when the notify calls are broadcast to registered clients. Ideally if possible, we could disable_preempt() at the highest caller and make sure we dont sleep in the path down in cpufreq->driver_target() calls but the calls are so intertwined and cumbersome to cleanup. Hence we consistently use lock_cpu_hotplug() and unlock_cpu_hotplug() in all places. - Removed export of cpucontrol semaphore and made it static. - removed explicit uses of up/down with lock_cpu_hotplug() so we can keep track of the the callers in same thread context and just keep refcounts without calling a down() that causes a deadlock. - Removed current_in_hotplug() uses - Removed PF_HOTPLUG_CPU in sched.h introduced for the current_in_hotplug() temporary workaround. Tested with insmod of cpufreq_stat.ko, and logical online/offline to make sure we dont have any hang situations.

| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* | [PATCH] powerpc: More hugepage boundary case fixesDavid Gibson2005-11-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Blah. The patch [0] I recently sent fixing errors with in_hugepage_area() and prepare_hugepage_range() for powerpc itself has an off-by-one bug. Furthermore, the related functions touches_hugepage_*_range() and within_hugepage_*_range() are also buggy. Some of the bugs, like those addressed in [0] originated with commit 7d24f0b8a53261709938ffabe3e00f88f6498df9 where we tweaked the semantics of where hugepages are allowed. Other bugs have been there essentially forever, and are due to the undefined behaviour of '<<' with shift counts greater than the type width (LOW_ESID_MASK could return non-zero for high ranges with the right congruences). The good news is that I now have a testsuite which should pick up things like this if they creep in again.

Unfortunately, it left out a couple of necessary changes to go with that change. First, the in_hugepage_area() macro was not updated to match, second prepare_hugepage_range() was not updated to correctly handle hugepages regions which straddled the 4GB point. The latter appears only to cause process-hangs when attempting to map such a region, but the former can cause oopses if a get_user_pages() is triggered at the wrong point.

* [PATCH] unpaged: VM_UNPAGEDHugh Dickins2005-11-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Although we tend to associate VM_RESERVED with remap_pfn_range, quite a few drivers set VM_RESERVED on areas which are then populated by nopage. The PageReserved removal in 2.6.15-rc1 changed VM_RESERVED not to free pages in zap_pte_range, without changing those drivers not to set it: so their pages just leak away. Let's not change miscellaneous drivers now: introduce VM_UNPAGED at the core, to flag the special areas where the ptes may have no struct page, or if they have then it's not to be touched. Replace most instances of VM_RESERVED in core mm by VM_UNPAGED. Force it on in remap_pfn_range, and the sparc and sparc64 io_remap_pfn_range. Revert addition of VM_RESERVED to powerpc vdso, it's not needed there. Is it needed anywhere? It still governs the mm->reserved_vm statistic, and special vmas not to be merged, and areas not to be core dumped; but could probably be eliminated later (the drivers are probably specifying it because in 2.4 it kept swapout off the vma, but in 2.6 we work from the LRU, which these pages don't get on). Use the VM_SHM slot for VM_UNPAGED, and define VM_SHM to 0: it serves no purpose whatsoever, and should be removed from drivers when we clean up.
