Add two new functions for reading the kernel log buffer. The intention is for them to be used by recovery/dump/debug code so the kernel log can be easily retrieved/parsed in a crash scenario, but they are generic enough for other people to dream up other fun uses.

This patch adds the /sys/module/<name>/notes/ magic directory, which has a file for each allocated SHT_NOTE section that appears in <name>.ko. This is the counterpart for each module of /sys/kernel/notes for vmlinux. Reading this delivers the contents of the module's SHT_NOTE sections. This lets userland easily glean any detailed information about that module's build that was stored there at compile time (e.g. by ld --build-id). Signed-off-by:

* Remove stupid comments, like, at the beginning of every function that function begins (twice per function) and at the end (once) * Remove trailing or otherwise broken whitespace as per let c_space_errors=1 * Reformat comments to fit it into 80 columns and remove stupid ------------'s. * Indent case labels on the same column where switch begins * other minor CS tweaks not worth mentioning Signed-off-by:

A rewrite of my previous post for this enhancement. It uses jeremy's split_argv/free_argv library functions to translate core_pattern into an argv array to be passed to the user mode helper process. It also adds a translation to format_corename such that the origional value of RLIMIT_CORE can be passed to userspace as an argument. Signed-off-by:

For some time /proc/sys/kernel/core_pattern has been able to set its output destination as a pipe, allowing a user space helper to receive and intellegently process a core. This infrastructure however has some shortcommings which can be enhanced. Specifically: 1) The coredump code in the kernel should ignore RLIMIT_CORE limitation when core_pattern is a pipe, since file system resources are not being consumed in this case, unless the user application wishes to save the core, at which point the app is restricted by usual file system limits and restrictions. 2) The core_pattern code should be able to parse and pass options to the user space helper as an argv array. The real core limit of the uid of the crashing proces should also be passable to the user space helper (since it is overridden to zero when called). 3) Some miscellaneous bugs need to be cleaned up (specifically the recognition of a recursive core dump, should the user mode helper itself crash. Also, the core dump code in the kernel should not wait for the user mode helper to exit, since the same context is responsible for writing to the pipe, and a read of the pipe by the user mode helper will result in a deadlock. This patch: Remove the check of RLIMIT_CORE if core_pattern is a pipe. In the event that core_pattern is a pipe, the entire core will be fed to the user mode helper. Signed-off-by:

It would be nice if the argv_split library function could gracefully handle a NULL pointer in the argcp parameter, so as to allow functions using it that did not care about the value of argc to not have to declare a useless variable. This patch accomplishes that. Tested by me, with successful results. Signed-off-by:

Add in support for SunOS 4.1.x flavor of BSD 4.2 UFS filing system Macros have been put in to alow suport for the old static table Cylinder Groups but this implementation does not use them yet. This also fixes Solaris UFS filing system access by disabling fast symbolic links as Sun's version of UFS does not support on-disk fast symbolic links. Tested by: Ppartitioning a new disk using SunOS 4.1.1, creating a UFS filing system on one of the partitions and writing some files to the filing system. Using Linux-2.6.22 (patched) to read the files and then write a shed load of files to the UFS partition. Using SunOS 4.1.1 to verify the filing system is OK and to check the files. The test host is a sun4c SS1 Clone. [akpm@linux-foundation.org: coding style fixes] [adobriyan@gmail.com: fix oops] Signed-off-by:

ext[234]_get_group_desc never tests the bh argument, and only sets it if it is passed in; it is perfectly happy with a NULL bh argument. But, many callers send one in and never use it. May as well call with NULL like other callers who don't use the bh. Signed-off-by:

Since the mempages parameter is actually not used, they should be removed. Now there is only files_init use the mempages parameter, files_init(mempages); but I don't think the adaptation to mempages in files_init is really useful; and if files_init also changed to the prototype void (*func)(void), the wrapper vfs_caches_init would also not need the mempages parameter.

Andy Gospodarek pointed out that because we return in the middle of the free_irq() function, we never actually do call the IRQ handler that just got deregistered. This should fix it, although I expect Andrew will want to convert those 'return's to 'break'. That's a separate change though. Signed-off-by:

Commit 4004c69a avoids too many remote cpu references while reporting per-irq stats. Since we will not have the same performance penalty of bringing in remote cpu cachelines while reporting per-irq stats anymore, we can now afford to be consistent and report this statistic on all arches, all configs. akpm: affects ia64, alpha and ppc64, mainly. Kiran earlier said: Read to /proc/stat takes: Plain: 2.622832 With speedup patch: 0.013194 With the per-irq stats commented out: 0.008124 So the performance problems which originally caused those architectures to disable this statistic should now be fixed up.

Adrian Bunk points out that "unsafe" was used to mark modules touched by the deprecated MOD_INC_USE_COUNT interface, which has long gone. It's time to remove the member from the module structure, as well. If you want a module which can't unload, don't register an exit function. (Vlad Yasevich says SCTP is now safe to unload, so just remove the __unsafe there). Signed-off-by:

Using mtab is problematic for various reasons, one of them is that unprivileged mounts won't turn up in there. So we want to get rid of it, and use /proc/mounts instead. But most filesystems are lazy, and are not showing all mount options. Which means, that without mtab, the user won't be able to see some or all of the options. It would be nice if the generic code could remember the mount options, and show them without the need to add extra code to filesystems. But this is not easy, because different filesystems handle mount options given options, and not tough the rest. This is not taken into account by mount(8) either, so /etc/mtab will be broken in this case. This series fixes up ->show_options() in ext[234]. Signed-off-by:

It's *wrong* to have #define log2(n) ffz(~(n)) It should be *reversed*: #define log2(n) flz(~(n)) or #define log2(n) fls(n) or just use ilog2(n) defined in linux/log2.h.

Driver for the CompactFlash slot on the PA Semi Electra eval board. It's a simple device sitting on localbus, with interrupts and detect/voltage control over GPIO. The driver is implemented as an of_platform driver, and adds localbus as a bus being probed by the of_platform framework.

fs/proc/mmu.c consists of only one function which uses only: 1) struct vmalloc_info * 2) struct vm_struct * 3) struct vmalloc_info 4) vmlist 5) VMALLOC_TOTAL, VMALLOC_START, VMALLOC_END 6) read_lock, read_unlock 7) vmlist_lock 8) struct vm_struct This gives us linux/spinlock.h, asm/pgtable.h, "internal.h", linux/vmalloc.h. asm/pgtable.h uses PKMAP_BASE on i386, for which asm/highmem.h is needed. But, linux/highmem.h is actually used to make it compile everywhere. I'll deal later with this particular i386 surprise. Cross-compile tested on many archs and configs. Signed-off-by:

Cleanup. Lessens both the source and compiled code (100 bytes) and imho makes the code much more understandable. With this patch "struct poll_list *head" always points to on-stack stack_pps, so we can remove all "is it on-stack" and "was it initialized" checks. Also, move poll_initwait/poll_freewait and -EINTR detection closer to the do_poll()'s callsite. [akpm@linux-foundation.org: fix warning (size_t != uint)] Signed-off-by:
