2006-09-27[PATCH] sysctl: Allow /proc/sys without sys_sysctlEric W. Biederman
Since sys_sysctl is deprecated start allow it to be compiled out. This should catch any remaining user space code that cares, and paves the way for further sysctl cleanups.

2006-09-26[SPARC64]: Kill bogus check from bootmem_init().David S. Miller
There is an ancient and totally incorrect sanity check being done on the ramdisk location. The check assumes that the kernel is always loaded to physical address zero, which is wrong. It was trying to validate the ramdisk value by saying that if it fell within the kernel image address range it must be wrong. Anyways, kill this because it actually creates problems. The 'ramdisk_image' should always be adjusted down by KERNBASE. SILO can easily put the ramdisk in a location which causes this test to trigger, breaking things.

2006-09-23[SPARC64]: Fix sched_clock() wrapping every ~17 seconds.David S. Miller
Unfortunately, sparc64 doesn't have an easy way to do a "64 X 64 --> 128" bit multiply like PowerPC and IA64 do. We were doing a "64 X 64 --> 64" bit multiple which causes overflow very quickly with a 30-bit quotient shift. So use a quotientshift count of 10 instead of 30, just like x86 and ARM do. This also fixes the wrapping of printk timestamp values every ~17 seconds. Signed-off-by: David S. Miller <davem@davemloft.net>

2006-09-08[PATCH] IA64,sparc: local DoS with corrupted ELFsKirill Korotaev
This prevents cross-region mappings on IA64 and SPARC which could lead to system crash. They were correctly trapped for normal mmap() calls, but not for the kernel internal calls generated by executable loading. This code just moves the architecture-specific cross-region checks into an arch-specific "arch_mmap_check()" macro, and defines that for the architectures that needed it (ia64, sparc and sparc64). Architectures that don't have any special requirements can just ignore the new cross-region check, since the mmap() code will just notice on its own when the macro isn't defined.

2006-08-29[SPARC64]: Fix X server hangs due to large pages.David S. Miller
This problem was introduced by changeset 14778d9072e53d2171f66ffd9657daff41acfaed Unlike the hugetlb code paths, the normal fault code is not setup to propagate PTE changes for large page sizes correctly like the ones we make for I/O mappings in io_remap_pfn_range(). It is absolutely necessary to update all sub-ptes of a largepage mapping on a fault. Adding special handling for this would add considerably complexity to tlb_batch_add(). So let's just side-step the issue and forcefully dirty any writable PTEs created by io_remap_pfn_range(). The only other real option would be to disable to large PTE code of io_remap_pfn_range() and we really don't want to do that. Much thanks to Mikael Pettersson for tracking down this problem and testing debug patches. Signed-off-by: David S. Miller <davem@davemloft.net>

2006-07-21[SPARC64]: Fix more of_device layer IRQ bugs, and correct PROMREG_MAX.David S. Miller
Sabre and Psycho PCI controllers can have partial interrupt-map properties, meaning that on-board devices don't match up to any entries. Instead, they are fully specified from the beginning and we should pass them directly to the IRQ translator as-is. Also, fill in the necessary translator slots for the "graphics" and "expansion UPA" interrupts on Sabre, Psycho, and SYSIO SBUS. Increase PROMREG_MAX to 24, as seen on SUNW,ffb devices. Finally, prevent accidentally writing past the end of the of_device struct resource[] and irqs[] arrays. Spit out a log message when we ignore some entries because there are too many of them.

2006-07-13[SPARC]: Fix OF register translations under sub-PCI busses.David S. Miller
There is an implicit assumption in the code that ranges will translate to something that can fit in 2 32-bit cells, or a 64-bit value. For certain kinds of things below PCI this isn't necessarily true. Here is what the relevant OF device hierarchy looks like for one of the serial controllers on an Ultra5: Node 0xf005f1e0 ranges: 00000000.00000000.00000000.000001fe.01000000.00000000.01000000 01000000.00000000.00000000.000001fe.02000000.00000000.01000000 02000000.00000000.00000000.000001ff.00000000.00000001.00000000 03000000.00000000.00000000.000001ff.00000000.00000001.00000000 device_type: 'pci' model: 'SUNW,sabre' Node 0xf005f9d4 device_type: 'pci' model: 'SUNW,simba' Node 0xf0060d24 ranges: 00000010.00000000 82010810.00000000.f0000000 01000000 00000014.00000000 82010814.00000000.f1000000 00800000 name: 'ebus' Node 0xf0062dac reg: 00000014.003083f8.00000008 --> 0x1ff.f13083f8 device_type: 'serial' name: 'su' So the correct translation here is: 1) Match "su" register to second ranges entry of 'ebus', which translates into a PCI triplet "82010814.00000000.f1000000" of size 00800000, which gives us "82010814.00000000.f13083f8". 2) Pass-through "SUNW,simba" since it lacks ranges property 3) Match "82010814.00000000.f13083f8" to third ranges property of PCI controller node 'SUNW,sabre', and we arrive at the final physical MMIO address of "0x1fff13083f8". Due to the 2-cell assumption, we couldn't translate to a PCI 3-cell value, and we couldn't perform a pass-thru on it either. It was easiest to just stop splitting the ranges application operation between two methods, ->map and ->translate, and just let ->map do all the work. That way it would work purely on 32-bit cell arrays instead of having to "return" some value like a u64. It's still not %100 correct because the out-of-range check is still done using the 64 least significant bits of the range and address. But it does work for all the cases I've thrown at it so far.

2006-07-10[PATCH] disallow modular binfmt_elf32Christoph Hellwig
Currently most architectures either always build binfmt_elf32 in the kernel image or make it a boolean option. Only sparc64 and s390 allow to build it modularly. This patch turns the option into a boolean aswell because elf requires various symbols that shouldn't be available to modules. The most urgent one is tasklist_lock whos export this patch series kills, but there are others like force_sgi aswell. Note that sparc doesn't allow a modular 32bit a.out handler either, and that would be the more useful case as only few people want 32bit sunos compatibility and 99.9% of all sparc64 users need 32bit linux native elf support.

2006-06-30[PATCH] zoned vm counters: conversion of nr_pagecache to per zone counterChristoph Lameter
Currently a single atomic variable is used to establish the size of the page cache in the whole machine. The zoned VM counters have the same method of implementation as the nr_pagecache code but also allow the determination of the pagecache size per zone. Remove the special implementation for nr_pagecache and make it a zoned counter named NR_FILE_PAGES. Updates of the page cache counters are always performed with interrupts off. We can therefore use the __ variant here.

2006-06-29[SPARC64]: of_device layer IRQ resolutionDavid S. Miller
Do IRQ determination generically by parsing the PROM properties, and using IRQ controller drivers for final resolution. One immediate positive effect is that all of the IRQ frobbing in the EBUS, ISA, and PCI controller layers has been eliminated. We just look up the of_device and use the properly computed value. The PCI controller irq_build() routines are gone and no longer used. Unfortunately sbus_build_irq() has to remain as there is a direct reference to this in the sunzilog driver. That can be killed off once the sparc32 side of this is written and the sunzilog driver is transformed into an "of" bus driver. Signed-off-by: David S. Miller <davem@davemloft.net>
