2005-11-29[PATCH] process events connector: uid_t gid_t size issuesMatt Helsley
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.

2005-11-29[ATM]: deregistration removes device from atm_devs list immediatelyStanislaw Gruszka
atm_dev_deregister() removes device from atm_dev list immediately to prevent operations on a phantom device. Decision to free device based only on ->refcnt now. Remove shutdown_atm_dev() use atm_dev_deregister() instead. atm_dev_deregister() also asynchronously releases all vccs related to device.

2005-11-29Support strange discontiguous PFN remappingsLinus Torvalds
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>
2005-11-29[MTD] CFI: Use 16-bit access to autoselect/read device id dataTodd Poynor
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.

2005-11-28[PATCH] temporarily disable swap token on memory pressureRik van Riel
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. This patch resolves the problem Zwane ran into. Signed-off-by: Rik van Riel <riel@redhat.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2005-11-28[PATCH] FRV: Make the FRV arch work againDavid Howells
The attached patch implements a bunch of small changes to the FRV arch to make it work again. 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.

2005-11-28[PATCH] clean up lock_cpu_hotplug() in cpufreqAshok Raj
There are some callers in cpufreq hotplug notify path that the lowest function calls lock_cpu_hotplug(). 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.

2005-11-28mm: re-architect the VM_UNPAGED logicLinus Torvalds
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>

2005-11-25[PATCH] powerpc: More hugepage boundary case fixesDavid Gibson
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.

2005-11-23[PATCH] powerpc: fix for hugepage areas straddling 4GB boundaryDavid Gibson
Commit 7d24f0b8a53261709938ffabe3e00f88f6498df9 fixed bugs in the ppc64 SLB miss handler with respect to hugepage handling, and in the process tweaked the semantics of the hugepage address masks in mm_context_t. 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.

2005-11-22[PATCH] unpaged: VM_UNPAGEDHugh Dickins
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.

2005-11-22[PATCH] unpaged: unifdefed PageCompoundHugh Dickins
It looks like snd_xxx is not the only nopage to be using PageReserved as a way of holding a high-order page together: which no longer works, but is masked by our failure to free from VM_RESERVED areas. We cannot fix that bug without first substituting another way to hold the high-order page together, while farming out the 0-order pages from within it. That's just what PageCompound is designed for, but it's been kept under CONFIG_HUGETLB_PAGE. Remove the #ifdefs: which saves some space (out- of-line put_page), doesn't slow down what most needs to be fast (already using hugetlb), and unifies the way we handle high-order pages.
