2008-10-20memcg: avoid accounting special pagesKAMEZAWA Hiroyuki1-8/+16
There are not-on-LRU pages which can be mapped and they are not worth to be accounted. (becasue we can't shrink them and need dirty codes to handle specical case) We'd like to make use of usual objrmap/radix-tree's protcol and don't want to account out-of-vm's control pages. When special_mapping_fault() is called, page->mapping is tend to be NULL and it's charged as Anonymous page. insert_page() also handles some special pages from drivers. This patch is for avoiding to account special pages.

2008-10-20ext3: add an option to control error handling on file dataHidehiro Kawai1-0/+5
If the journal doesn't abort when it gets an IO error in file data blocks, the file data corruption will spread silently. Because most of applications and commands do buffered writes without fsync(), they don't notice the IO error. It's scary for mission critical systems. On the other hand, if the journal aborts whenever it gets an IO error in file data blocks, the system will easily become inoperable. So this patch introduces a filesystem option to determine whether it aborts the journal or just call printk() when it gets an IO error in file data. If you mount a ext3 fs with data_err=abort option, it aborts on file data write error. If you mount it with data_err=ignore, it doesn't abort, just call printk(). data_err=ignore is the default.

2008-10-20documentation: clarify dirty_ratio and dirty_background_ratio descriptionAndrea Righi1-5/+8
The current documentation of dirty_ratio and dirty_background_ratio is a bit misleading. In the documentation we say that they are "a percentage of total system memory", but the current page writeback policy, intead, is to apply the percentages to the dirtyable memory, that means free pages + reclaimable pages. Better to be more explicit to clarify this concept.

2008-10-20coredump_filter: add hugepage dumpingKOSAKI Motohiro1-5/+10
Presently hugepage's vma has a VM_RESERVED flag in order not to be swapped. But a VM_RESERVED vma isn't core dumped because this flag is often used for some kernel vmas (e.g. vmalloc, sound related). Thus hugepages are never dumped and it can't be debugged easily. Many developers want hugepages to be included into core-dump. However, We can't read generic VM_RESERVED area because this area is often IO mapping area. then these area reading may change device state. it is definitly undesiable side-effect. So adding a hugepage specific bit to the coredump filter is better. It will be able to hugepage core dumping and doesn't cause any side-effect to any i/o devices. In additional, libhugetlb use hugetlb private mapping pages as anonymous page. Then, hugepage private mapping pages should be core dumped by default. Then, /proc/[pid]/core_dump_filter has two new bits. - bit 5 mean hugetlb private mapping pages are dumped or not. (default: yes) - bit 6 mean hugetlb shared mapping pages are dumped or not. (default: no) I tested by following method. % ulimit -c unlimited % ./crash_hugepage 50 % ./crash_hugepage 50 -p % ls -lh % gdb ./crash_hugepage core % % echo 0x43 > /proc/self/coredump_filter % ./crash_hugepage 50 % ./crash_hugepage 50 -p % ls -lh % gdb ./crash_hugepage core #include <stdlib.h> #include <stdio.h> #include <unistd.h> #include <sys/mman.h> #include <string.h> #include "hugetlbfs.h" int main(int argc, char** argv){ char* p; int ch; int mmap_flags = MAP_SHARED; int fd; int nr_pages; while((ch = getopt(argc, argv, "p")) != -1) { switch (ch) { case 'p': mmap_flags &= ~MAP_SHARED; mmap_flags |= MAP_PRIVATE; break; default: /* nothing*/ break; } } argc -= optind; argv += optind; if (argc == 0){ printf("need # of pages\n"); exit(1); } nr_pages = atoi(argv[0]); if (nr_pages < 2) { printf("nr_pages must >2\n"); exit(1); } fd = hugetlbfs_unlinked_fd(); p = mmap(NULL, nr_pages * gethugepagesize(), PROT_READ|PROT_WRITE, mmap_flags, fd, 0); sleep(2); *(p + gethugepagesize()) = 1; /* COW */ sleep(2); /* crash! */ *(int*)0 = 1; return 0; } Signed-off-by: KOSAKI Motohiro <kosaki.motohiro@jp.fujitsu.com> Reviewed-by: Kawai Hidehiro <hidehiro.kawai.ez@hitachi.com> Cc: Hugh Dickins <hugh@veritas.com> Cc: William Irwin <wli@holomorphy.com> Cc: Adam Litke <agl@us.ibm.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

This patch adds initial_descriptor_timeout module parameter for usbcore.ko to allow modify initial 64-byte USB_REQ_GET_DESCRIPTOR timeout for non-standard devices. For example, the SATA8000 device from DATAST0R Technology Corp requires about 10 seconds to send reply (probably it waits until inserted disk is ready for operation).

The it87 driver doesn't follow the standard sensor type values as documented in Documentation/hwmon/sysfs-interface. It uses value 2 for thermistors instead of value 4. This causes "sensors" to tell the user that the chip is setup for a transistor while it is actually setup for a thermistor. Using value 4 for thermistors solves the problem. For compatibility reasons, we still accept value 2 but emit a warning message so that users update their configuration files.

2008-10-16intelfb: support 945GME (as used in ASUS Eee 901)Phil Endecott1-0/+1
Add support for Intel's 945GME graphics chip to the intelfb driver. I have assumed that the 945GME is identical to the already-supported 945GM apart from its PCI IDs; this is based on a quick look at the X driver for these chips which seems to treat them identically. The 945GME is used in the ASUS Eee 901, and I coded this in the hope that I'd be able to use it to get a console at the native 1024x600 resolution which is not known to the BIOS. I realised too late that the intelfb driver does not support mode changing on laptops, so it won't be any use for me.

2008-10-16gpiolib: request/free hooksDavid Brownell1-0/+4
Add a new internal mechanism to gpiolib to support low power operations by letting gpio_chip instances see when their GPIOs are in use. When no GPIOs are active, chips may be able to enter lower powered runtime states by disabling clocks and/or power domains.

2008-10-16gpiolib: gpio_to_irq() hooksDavid Brownell1-2/+3
Add a new gpiolib mechanism: gpio_chip instances can provide mappings between their (input) GPIOs and any associated IRQs. This makes it easier for platforms to support IRQs that are provided by board-specific external chips instead of as part of their core (such as SOC-integrated GPIOs). Also update the irq_to_gpio() description, saying to avoid it because it's not always supported.
