* [PATCH] __vmalloc with GFP_ATOMIC causes 'sleeping from invalid context'Giridhar Pemmasani2006-10-28
| | | | | | | | | | | If __vmalloc is called to allocate memory with GFP_ATOMIC in atomic context, the chain of calls results in __get_vm_area_node allocating memory for vm_struct with GFP_KERNEL, causing the 'sleeping from invalid context' warning. This patch fixes it by passing the gfp flags along so __get_vm_area_node allocates memory for vm_struct with the same flags.

* [PATCH] vmscan: Fix temp_priority raceMartin Bligh2006-10-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The temp_priority field in zone is racy, as we can walk through a reclaim path, and just before we copy it into prev_priority, it can be overwritten (say with DEF_PRIORITY) by another reclaimer. The same bug is contained in both try_to_free_pages and balance_pgdat, but it is fixed slightly differently. In balance_pgdat, we keep a separate priority record per zone in a local array. In try_to_free_pages there is no need to do this, as the priority level is the same for all zones that we reclaim from. Impact of this bug is that temp_priority is copied into prev_priority, and setting this artificially high causes reclaimers to set distress artificially low. They then fail to reclaim mapped pages, when they are, in fact, under severe memory pressure (their priority may be as low as 0). This causes the OOM killer to fire incorrectly. From: Andrew Morton <akpm@osdl.org> __zone_reclaim() isn't modifying zone->prev_priority. But zone->prev_priority is used in the decision whether or not to bring mapped pages onto the inactive list. Hence there's a risk here that __zone_reclaim() will fail because zone->prev_priority ir large (ie: low urgency) and lots of mapped pages end up stuck on the active list. Fix that up by decreasing (ie making more urgent) zone->prev_priority as __zone_reclaim() scans the zone's pages. This bug perhaps explains why ZONE_RECLAIM_PRIORITY was created. It should be possible to remove that now, and to just start out at DEF_PRIORITY?

* [PATCH] drivers: wait for threaded probes between initcall levelsAndrew Morton2006-10-27
| | | | | | | | | | | | | | | | | | The multithreaded-probing code has a problem: after one initcall level (eg, core_initcall) has been processed, we will then start processing the next level (postcore_initcall) while the kernel threads which are handling core_initcall are still executing. This breaks the guarantees which the layered initcalls previously gave us. IOW, we want to be multithreaded _within_ an initcall level, but not between different levels. Fix that up by causing the probing code to wait for all outstanding probes at one level to complete before we start processing the next level.

* [PATCH] AVR32: add io{read,write}{8,16,32}{be,} supportBen Nizette2006-10-25
| | | | | | | | | | | | | | | | A number of new drivers require io{read,write}{8,16,32}{be,} family of io operations. These are provided for the AVR32 by this patch in the form of a series of macros. Access to the (memory mapped) io space through these macros is defined to be little endian only as little endian devices (such as PCI) are the main consumer of IO access. If high speed access is required, io{read,write}{16,32}be macros are supplied to perform native big endian access to this io space.

We could hack around netlink's lack of mempool support like dm, but it is just too ulgy (dm's hack is ugly enough :) when you need to support broadcast. This patch removes the recv pools. We have not used them even when we were allocting 20 MB per session and the system only had 64 MBs. And we have no pools on the send side and have been ok there. When Peter's work gets merged we can use that since the network guys are in favor of that approach and are not going to add mempools everywhere.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When I generalized __assign_irq_vector I failed to pay attention to what happens when you access a per cpu data structure for a cpu that is not online. It is an undefined case making any code that does it have undefined behavior as well. The code still needs to be able to allocate a vector across cpus that are not online to properly handle combinations like lowest priority interrupt delivery and cpu_hotplug. Not that we can do that today but the infrastructure shouldn't prevent it. So this patch updates the places where we touch per cpu data to only touch online cpus, it makes cpu vector allocation an atomic operation with respect to cpu hotplug, and it updates the cpu start code to properly initialize vector_irq so we don't have inconsistencies.

When reading the entire 64 bits of the timebase with one mftb instruction, there is a handful of cycles window during which one might read a value with the low order 32 bits already reset to 0x00000000 but the high order bits not yet incremeted by one. This fixes it by reading the timebase again until the low order 32 bits is no longer 0. That might introduce occasional latencies if hitting mftb just at the wrong time, but no more than 70ns on a cell blade, and that was considered acceptable.

| * | | [POWERPC] Support feature fixups in vdso'sBenjamin Herrenschmidt2006-10-24

The main issue was that the construct: .long label (or .llong on 64 bits) will not work in the case of a shared library like the vdso. It will generate an empty placeholder in the fixup table along with a reloc, which is not something we can deal with in the vdso. The idea here (thanks Alan Modra !) is to instead use something like: 1: .long label - 1b That is, the feature fixup tables no longer contain addresses of bits of code to patch, but offsets of such code from the fixup table entry itself. That is properly resolved by ld when building the .so's. I've modified the fixup mecanism generically to use that method for the rest of the kernel as well. Another trick is that the 32 bits vDSO included in the 64 bits kernel need to have a table in the 64 bits format. However, gas does not support 32 bits code with a statement of the form: .llong label - 1b (Or even just .llong label) That is, it cannot emit the right fixup/relocation for the linker to use to assign a 32 bits address to an .llong field. Thus, in the specific case of the 32 bits vdso built as part of the 64 bits kernel, we are using a modified macro that generates: .long 0xffffffff .llong label - 1b Note that is assumes that the value is negative which is enforced by the .lds (those offsets are always negative as the .text is always before the fixup table and gas doesn't support emiting the reloc the other way around).

This problem particularly showed up in relation to do_fpu_state_restore() which was inserted quite deeply in to the table and ended up scribbling over a slab object.

| * | sh: Cleanup board header directories.Paul Mundt2006-10-19
| | | | | | | | | | | | | | | | | | | | | | | | Now with the ide.h mess sorted out, most of these boards don't need their own directory. Move the headers out, and update the driver paths. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver that these were using never made it in to drivers/ide, so kill off the rest of the cruft. These will have to be reworked for board-specific platform devices through libata when they're added back through the setup code. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * | sh: Proper show_stack/show_trace() implementation.Paul Mundt2006-10-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This splits out some of the previous show_stack() implementation which was mostly doing the show_trace() work without actually dumping any of the stack contents. This now gets split in to two sections, where we do the fetching of the stack pointer and subsequent stack dumping in show_stack(), while moving the call trace in to show_trace().

* | | [MIPS] Fix aliasing bug in copy_to_user_page / copy_from_user_pageRalf Baechle2006-10-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current implementation uses a sequence of a cacheflush and a copy. This is racy in case of a multithreaded debuggee and renders GDB virtually unusable. Aside this fixes a performance hog rendering access to /proc/cmdline very slow and resulting in a enough cache stalls for the 34K AP/SP programming model to make the bare metal code on the non-Linux VPE miss RT deadlines. The main part of this patch was originally written by Ralf Baechle; Atushi Nemoto did the the debugging.

This should unbreak some Nvidia boards where the timer doesn't seem to tick of it isn't enabled in the 8259. At least one VIA board also seemed to have a little trouble with the disabled 8259. For 2.6.20 we'll try both dynamically without black listing, but I think for .19 this is the safer approach because it has been already well tested in earlier kernels. This also makes the x86-64 behaviour the same as i386. Command line options can change all this of course. Signed-off-by: Andi Kleen <ak@suse.de>

The linker is unfortunately not able to build a proper lookup table at link time, instead it creates one at runtime as soon as the bootmem allocator is usable (so you'll continue using the linear lookup for the first [hopefully] few calls). The code should be ready to utilize a build-time created table once a fixed linker becomes available. Signed-off-by: Jan Beulich <jbeulich@novell.com> Signed-off-by: Andi Kleen <ak@suse.de>
