2005-05-01[PATCH] nice and rt-prio rlimitsMatt Mackall
Add a pair of rlimits for allowing non-root tasks to raise nice and rt priorities. Defaults to traditional behavior. Originally written by Chris Wright. The patch implements a simple rlimit ceiling for the RT (and nice) priorities a task can set. The rlimit defaults to 0, meaning no change in behavior by default. A value of 50 means RT priority levels 1-50 are allowed. A value of 100 means all 99 privilege levels from 1 to 99 are allowed. CAP_SYS_NICE is blanket permission.

We want to make possible, for the user, to enable the i586 AES implementation. This requires a restructure. - Add a CONFIG_UML_X86 to notify that we are building a UML for i386. - Rename CONFIG_64_BIT to CONFIG_64BIT as is used for all other archs - Tell crypto/Kconfig that UML_X86 is as good as X86 - Tell it that it must exclude not X86_64 but 64BIT, which will give the same results. - Tell kbuild to descend down into arch/i386/crypto/ to build what's needed.

2005-05-01[PATCH] uml: fix oops related to exception tableJeff Dike
Paolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it> Prevent the kernel from oopsing during the extable sorting, as it can do now, because the extable is in the readonly section of the binary. Jeff says: The exception table turned RO in 2.6.11-rc3-mm1 for some reason. Moving it causes it to land in the writable data section of the binary. Paolo says: This patch fixes a oops on startup, which can be easily triggered by compiling with CONFIG_MODE_TT disabled, and STATIC_LINK either disabled or enabled. The resulting kernel will always Oops on startup, after printing this simple output: I've verified, by binary search on the BitKeeper repository (synced up as of 2.6.12-rc2), starting from the range 2.6.11-2.6.12-rc1, that this bug shows up on BitKeeper revisions in the range [@1.1994.11.168,+inf), i.e. starting from this: [PATCH] lib/sort: Replace insertion sort in exception tables Since UML does not use the exception table, it's likely that insertion sort didn't happen to write anything on the table.

2005-05-01[PATCH] Increase number of e820 entries hard limit from 32 to 128Venkatesh Pallipadi
The specifications that talk about E820 map doesn't have an upper limit on the number of e820 entries. But, today's kernel has a hard limit of 32. With increase in memory size, we are seeing the number of E820 entries reaching close to 32. Patch below bumps the number upto 128. The patch changes the location of EDDBUF in zero-page (as it comes after E820). As, EDDBUF is not used by boot loaders, this patch should not have any effect on bootloader-setup code interface. Patch covers both i386 and x86-64. Tested on: * grub booting bzImage * lilo booting bzImage with EDID info enabled * pxeboot of bzImage Side-effect: bss increases by ~ 2K and init.data increases by ~7.5K on all systems, due to increase in size of static arrays.

2005-05-01[PATCH] i386: fix hpet for systems that don't support legacy replacementjohn stultz
Currently the i386 HPET code assumes the entire HPET implementation from the spec is present. This breaks on boxes that do not implement the optional legacy timer replacement functionality portion of the spec. This patch, which is very similar to my x86-64 patch for the same issue, fixes the problem allowing i386 systems that cannot use the HPET for the timer interrupt and RTC to still use the HPET as a time source. I've tested this patch on a system systems without HPET, with HPET but without legacy timer replacement, as well as HPET with legacy timer replacement.

2005-05-01[PATCH] check nmi watchdog is brokenJack F Vogel
A bug against an xSeries system showed up recently noting that the check_nmi_watchdog() test was failing. I have been investigating it and discovered in both i386 and x86_64 the recent change to the routine to use the cpu_callin_map has uncovered a problem. Prior to that change, on an SMP box, the test was trivally passing because all cpu's were found to not yet be online, but now with the callin_map they are discovered, it goes on to test the counter and they have not yet begun to increment, so it announces a CPU is stuck and bails out. On all the systems I have access to test, the announcement of failure is also bougs... by the time you can login and check /proc/interrupts, the NMI count is happily incrementing on all CPUs. Its just that the test is being done too early. I have tried moving the call to the test around a bit, and it was always too early. I finally hit on this proposed solution, it delays the routine via a late_initcall(), seems like the right solution to me.

2005-05-01[PATCH] i386/x86_64 segment register access updateH. J. Lu
The new i386/x86_64 assemblers no longer accept instructions for moving between a segment register and a 32bit memory location, i.e., movl (%eax),%ds movl %ds,(%eax) To generate instructions for moving between a segment register and a 16bit memory location without the 16bit operand size prefix, 0x66, mov (%eax),%ds mov %ds,(%eax) should be used. It will work with both new and old assemblers. The assembler starting from 2.16.90.0.1 will also support movw (%eax),%ds movw %ds,(%eax) without the 0x66 prefix. I am enclosing patches for 2.4 and 2.6 kernels here. The resulting kernel binaries should be unchanged as before, with old and new assemblers, if gcc never generates memory access for unsigned gsindex; asm volatile("movl %%gs,%0" : "=g" (gsindex)); If gcc does generate memory access for the code above, the upper bits in gsindex are undefined and the new assembler doesn't allow it.

2005-05-01[PATCH] ppc64: reverse prediction on spinlock busy loop codeJake Moilanen
On our raw spinlocks, we currently have an attempt at the lock, and if we do not get it we enter a spin loop. This spinloop will likely continue for awhile, and we pridict likely. Shouldn't we predict that we will get out of the loop so our next instructions are already prefetched. Even when we miss because the lock is still held, it won't matter since we are waiting anyways. I did a couple quick benchmarks, but the results are inconclusive. 16-way 690 running specjbb with original code # ./specjbb 3000 16 1 1 19 30 120 ... Valid run, Score is 59282 16-way 690 running specjbb with unlikely code # ./specjbb 3000 16 1 1 19 30 120 ...

Valid run, Score is 20803 Anton said: Mispredicting the spinlock busy loop also means we slow down the rate at which we do the loads which can be good for heavily contended locks. Note: There are some gcc issues with our default build and branch prediction, but a CONFIG_POWER4_ONLY build should emit them correctly. I'm working with Alan Modra on it now.

2005-05-01[PATCH] ppc64: noexec fixesAnton Blanchard
There were a few issues with the ppc64 noexec support: The 64bit ABI has a non executable stack by default. At the moment 64bit apps require a PT_GNU_STACK section in order to have a non executable stack. Disable the read implies exec workaround on the 64bit ABI. The 64bit toolchain has never had problems with incorrect mmap permissions (the 32bit has, thats why we need to retain the workaround). With these fixes as well as a gcc fix from Alan Modra (that was recently committed) 64bit apps work as expected.

2005-05-01[PATCH] add kmalloc_node, inline cleanupManfred Spraul
The patch makes the following function calls available to allocate memory on a specific node without changing the basic operation of the slab allocator: kmem_cache_alloc_node(kmem_cache_t *cachep, unsigned int flags, int node); kmalloc_node(size_t size, unsigned int flags, int node); in a similar way to the existing node-blind functions: kmem_cache_alloc(kmem_cache_t *cachep, unsigned int flags); kmalloc(size, flags); kmem_cache_alloc_node was changed to pass flags and the node information through the existing layers of the slab allocator (which lead to some minor rearrangements). The functions at the lowest layer (kmem_getpages, cache_grow) are already node aware. Also __alloc_percpu can call kmalloc_node now.

2005-04-29[PATCH] ARM: 2651/3: kernel helpers for NPTL supportNicolas Pitre
Patch from Nicolas Pitre This patch entirely reworks the kernel assistance for NPTL on ARM. In particular this provides an efficient way to retrieve the TLS value and perform atomic operations without any instruction emulation nor special system call. This even allows for pre ARMv6 binaries to be forward compatible with SMP systems without any penalty. The problematic and performance critical operations are performed through segment of kernel provided user code reachable from user space at a fixed address in kernel memory. Those fixed entry points are within the vector page so we basically get it for free as no extra memory page is required and nothing else may be mapped at that location anyway. This is different from (but doesn't preclude) a full blown VDSO implementation, however a VDSO would prevent some assembly tricks with constants that allows for efficient branching to those code segments. And since those code segments only use a few cycles before returning to user code, the overhead of a VDSO far call would add a significant overhead to such minimalistic operations. The ARM_NR_set_tls syscall also changed number. This is done for two reasons: 1) this patch changes the way the TLS value was previously meant to be retrieved, therefore we ensure whatever library using the old way gets fixed (they only exist in private tree at the moment since the NPTL work is still progressing). 2) the previous number was allocated in a range causing an undefined instruction trap on kernels not supporting that syscall and it was determined that allocating it in a range returning -ENOSYS would be much nicer for libraries trying to determine if the feature is present or not.

2005-04-28[PATCH] ARM: AMBA CLCD: X resolutions must be multiples of 16Russell King
We ignore the bottom 4 bits of the X resolution, so we should round X resolutions up to the nearest multiple of 16. Signed-off-by: Russell King <rmk@arm.linux.org.uk>
2005-04-28[PATCH] ARM: Fix AMBA CLCD fb driver for 32bppRussell King
We were supporting 24bpp. However, the pixel organisation in memory was 0RGB, so it was 24bpp in 32bit words. This means we're actually supporting 32bpp and not 24bpp. Also, add a check to ensure that we don't exceed the available framebuffer when changing display resolutions.

2005-04-26[IA64] re-enable preempt before page allocation for pgtable quicklistMartin Hicks
This is a fix to the pgtable_quicklist code. There is a GFP_KERNEL allocation in pgtable_quicklist_alloc(), which spews the usual warnings if the kernel is under heavy VM pressure and the reclaim code is invoked. re-enable preempt before we allocate the new page.

2005-04-25[PATCH] isofs includes sanitizedAl Viro
fs/isofs includes trimmed down to something resembling sanity. Kernel-only parts of linux/iso_fs.h and entire linux/iso_fs_{sb,i}.h moved to fs/isofs/isofs.h. A lot of useless #include in fs/isofs/*.c killed. Signed-off-by: Al Viro <viro@parcelfarce.linux.theplanet.co.uk> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2005-04-25[PATCH] ARM: 2653/1: Fix memset and memzero macro double-reference of parametersDeepak Saxena
Patch from Deepak Saxena The current memset() and memzero() macros on ARM reference the incoming parameters more than once and this can cause uninted side-effects. The issue was found while debugging SCTP protocol and with the specific usage of memzero(skb_put(skb,size),size). This call would call skb_put(skb,size) twice leading to badness. The fixed version copies the incoming parameters into local variables and uses those instead. Signed-off-by: Deepak Saxena Signed-off-by: Russell King

Patch from Lucas Correia Villa Real The S3C2400 doesn't have a cpuid information stored anywhere. This patch adds support to the S3C2400 at include/asm-arm/arch-s3c2400/uncompress.h by initializing the cpuid variable to the S3C2410, as they share the same routine. The GSTATUS1 pin is then used only if not compiling for the S3C2400. Signed-off-by: Lucas Correia Villa Real Signed-off-by: Ben Dooks Signed-off-by: Russell King
2005-04-25[IA64] Altix system controller event handlingGreg Howard
The following is an update of the patch I sent yesterday (3/9/05) incorporating suggestions from Christoph Hellwig and Andreas Schwab. It allows Altix and Altix-like systems to handle environmental events generated by the system controllers, and should apply on top of Jack Steiner's patch of 3/1/05 ("New chipset support for SN platform") and Mark Goodwin's patch of 3/8/05 ("Altix SN topology support for new chipsets and pci topology").
