2010-01-11mmc_block: fix queue cleanupAdrian Hunter2-9/+11
The main bug was that 'blk_cleanup_queue()' was called while the block device could still be in use, for example, because the card was removed while files were still open. In addition, to be sure that 'mmc_request()' will get called for all new requests (so it can error them out), the queue is emptied during cleanup. This is done after the worker thread is stopped to avoid racing with it. Finally, it is not a device error for this to be happening, so quiet the (sometimes very many) error messages.

2010-01-11mmc_block: add dev_t initialization checkAnna Lemehova1-0/+5

This caused mmc_blk_put() to always release devidx 0 even if 0 was still in use. Then the next mmc_blk_probe() used the first free idx of 0, which oopses in sysfs, since it is used by another card.

2010-01-11proc: partially revert "procfs: provide stack information for threads"KOSAKI Motohiro2-91/+0
Commit d899bf7b (procfs: provide stack information for threads) introduced to show stack information in /proc/{pid}/status. But it cause large performance regression. Unfortunately /proc/{pid}/status is used ps command too and ps is one of most important component. Because both to take mmap_sem and page table walk are heavily operation. If many process run, the ps performance is, [before d899bf7b] % perf stat ps >/dev/null Performance counter stats for 'ps': 4090.435806 task-clock-msecs # 0.032 CPUs 229 context-switches # 0.000 M/sec 0 CPU-migrations # 0.000 M/sec 234 page-faults # 0.000 M/sec 8587565207 cycles # 2099.425 M/sec 9866662403 instructions # 1.149 IPC 3789415411 cache-references # 926.409 M/sec 30419509 cache-misses # 7.437 M/sec 128.859521955 seconds time elapsed [after d899bf7b] % perf stat ps > /dev/null Performance counter stats for 'ps': 4305.081146 task-clock-msecs # 0.028 CPUs 480 context-switches # 0.000 M/sec 2 CPU-migrations # 0.000 M/sec 237 page-faults # 0.000 M/sec 9021211334 cycles # 2095.480 M/sec 10605887536 instructions # 1.176 IPC 3612650999 cache-references # 839.160 M/sec 23917502 cache-misses # 5.556 M/sec 152.277819582 seconds time elapsed Thus, this patch revert it. Fortunately /proc/{pid}/task/{tid}/smaps provide almost same information. we can use it. Commit d899bf7b introduced two features: 1) Add the annotattion of [thread stack: xxxx] mark to /proc/{pid}/task/{tid}/maps. 2) Add StackUsage field to /proc/{pid}/status. I only revert (2), because I haven't seen (1) cause regression.

2010-01-11kernel/signal.c: fix kernel information leak with print-fatal-signals=1Andi Kleen1-1/+2
When print-fatal-signals is enabled it's possible to dump any memory reachable by the kernel to the log by simply jumping to that address from user space. Or crash the system if there's some hardware with read side effects. The fatal signals handler will dump 16 bytes at the execution address, which is fully controlled by ring 3. In addition when something jumps to a unmapped address there will be up to 16 additional useless page faults, which might be potentially slow (and at least is not very efficient) Fortunately this option is off by default and only there on i386. But fix it by checking for kernel addresses and also stopping when there's a page fault.

2010-01-11cgroups: fix 2.6.32 regression causing BUG_ON() in cgroup_diput()Dave Anderson1-1/+0
The LTP cgroup test suite generates a "kernel BUG at kernel/cgroup.c:790!" here in cgroup_diput(): /* * if we're getting rid of the cgroup, refcount should ensure * that there are no pidlists left. */ BUG_ON(!list_empty(&cgrp->pidlists)); The cgroup pidlist rework in 2.6.32 generates the BUG_ON, which is caused when pidlist_array_load() calls cgroup_pidlist_find(): (1) if a matching cgroup_pidlist is found, it down_write's the mutex of the pre-existing cgroup_pidlist, and increments its use_count. (2) if no matching cgroup_pidlist is found, then a new one is allocated, it down_write's its mutex, and the use_count is set to 0. (3) the matching, or new, cgroup_pidlist gets returned back to pidlist_array_load(), which increments its use_count -- regardless whether new or pre-existing -- and up_write's the mutex. So if a matching list is ever encountered by cgroup_pidlist_find() during the life of a cgroup directory, it results in an inflated use_count value, preventing it from ever getting released by cgroup_release_pid_array(). Then if the directory is subsequently removed, cgroup_diput() hits the BUG_ON() when it finds that the directory's cgroup is still populated with a pidlist. The patch simply removes the use_count increment when a matching pidlist is found by cgroup_pidlist_find(), because it gets bumped by the calling pidlist_array_load() function while still protected by the list's mutex.

2010-01-11lib: add support for LZO-compressed kernelsAlbin Tonnerre5-7/+244
This patch series adds generic support for creating and extracting LZO-compressed kernel images, as well as support for using such images on the x86 and ARM architectures, and support for creating and using LZO-compressed initrd and initramfs images. Russell King said: : Testing on a Cortex A9 model: : - lzo decompressor is 65% of the time gzip takes to decompress a kernel : - lzo kernel is 9% larger than a gzip kernel : : which I'm happy to say confirms your figures when comparing the two. : : However, when comparing your new gzip code to the old gzip code: : - new is 99% of the size of the old code : - new takes 42% of the time to decompress than the old code : : What this means is that for a proper comparison, the results get even better: : - lzo is 7.5% larger than the old gzip'd kernel image : - lzo takes 28% of the time that the old gzip code took : : So the expense seems definitely worth the effort. The only reason I : can think of ever using gzip would be if you needed the additional : compression (eg, because you have limited flash to store the image.) : : I would argue that the default for ARM should therefore be LZO. This patch: The lzo compressor is worse than gzip at compression, but faster at extraction. Here are some figures for an ARM board I'm working on: Uncompressed size: 3.24Mo gzip 1.61Mo 0.72s lzo 1.75Mo 0.48s So for a compression ratio that is still relatively close to gzip, it's much faster to extract, at least in that case. This part contains: - Makefile routine to support lzo compression - Fixes to the existing lzo compressor so that it can be used in compressed kernels - wrapper around the existing lzo1x_decompress, as it only extracts one block at a time, while we need to extract a whole file here - config dialog for kernel compression [akpm@linux-foundation.org: coding-style fixes] [akpm@linux-foundation.org: cleanup] Signed-off-by: Albin Tonnerre <albin.tonnerre@free-electrons.com> Tested-by: Wu Zhangjin <wuzhangjin@gmail.com> Acked-by: "H.

2010-01-11zlib: optimize inffast when copying direct from outputJoakim Tjernlund2-12/+47
JFFS2 uses lesser compression ratio and inflate always ends up in "copy direct from output" case. This patch tries to optimize the direct copy procedure. Uses get_unaligned() but only in one place. The copy loop just above this one can also use this optimization, but I havn't done so as I have not tested if it is a win there too. On my MPC8321 this is about 17% faster on my JFFS2 root FS than the original.

Fix resource (write-pipe file) leak in call_usermodehelper_pipe(). When call_usermodehelper_exec() fails, write-pipe file is opened and call_usermodehelper_pipe() just returns an error. Since it is hard for caller to determine whether the error occured when opening the pipe or executing the helper, the caller cannot close the pipe by themselves. I've found this resoruce leak when testing coredump. You can check how the resource leaks as below; $ echo "|nocommand" > /proc/sys/kernel/core_pattern $ ulimit -c unlimited $ while [ 1 ]; do ./segv; done &> /dev/null & $ cat /proc/meminfo (<- repeat it) where segv.c is; //----- int main () { char *p = 0; *p = 1; } //----- This patch closes write-pipe file if call_usermodehelper_exec() failed.

Commit cbda12d77ea590082edb6d30bd342a67ebc459e0 (drm/i915: implement new pm ops for i915), among other things, removed the .suspend and .resume pointers from the struct drm_driver object in i915_drv.c, which broke resume without KMS on my MSI Wind U100. Fix this by reverting that part of commit cbda12d77ea59. [ The DRM layer will not use the class-specific suspend/resume functions if the driver is marked MODESET-aware, and conversely it will not register the PCI device if the drievr isn't so marked, so you always end up with _either_ the drm-class suspend/resume _or_ the PCI layer PM functionality, never both. - Linus ] Signed-off-by: Rafael J.

2010-01-07[IA64] __per_cpu_idtrs[] is a memory hogTony Luck3-15/+24
__per_cpu_idtrs is statically allocated ... on CONFIG_NR_CPUS=4096 systems it hogs 16MB of memory. This is way too much for a quite probably unused facility (only KVM uses dynamic TR registers). Change to an array of pointers, and allocate entries as needed on a per cpu basis. Change the name too as the __per_cpu_ prefix is confusing (this isn't a classic <linux/percpu.h> type object).

2010-01-07blackfin,kgdb: Do not put PC in gdb_regs into retx.Sonic Zhang1-1/+1
In blackfin, kgdb is running in delayed exception IRQ5 other than in exception IRQ3 directly. Register reti other than retx in pt_regs is the kgdb return address. So, don't put PC in gdb_regs into retx. CC: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Sonic Zhang <sonic.adi@gmail.com> Signed-off-by: Jason Wessel <jason.wessel@windriver.com>
2010-01-07blackfin,kgdb,probe_kernel: Cleanup probe_kernel_read/writeJason Wessel3-206/+98
Blackfin needs it own arch specific probe_kernel_read() and probe_kernel_write(). This was moved out of the kgdb code and into the arch/blackfin/maccess.c, because it is a generic kernel api. The arch specific kgdb.c for blackfin was cleaned of all functions which exist in the kgdb core that do the same thing after resolving the probe_kernel_read() and probe_kernel_write(). This also eliminated the need for most of the #include's.

2010-01-07maccess,probe_kernel: Allow arch specific override probe_kernel_(read|write)Jason Wessel2-3/+12
Some archs such as blackfin, would like to have an arch specific probe_kernel_read() and probe_kernel_write() implementation which can fall back to the generic implementation if no special operations are needed.

2010-01-07reiserfs: Fix unreachable statementJiri Slaby1-1/+2
Stanse found an unreachable statement in reiserfs_ioctl. There is a if followed by error assignment and `break' with no braces. Add the braces so that we don't break every time, but only in error case, so that REISERFS_IOC_SETVERSION actually works when it returns no error.
