UUID/GUIDs are somewhat common in kernel source. Standardize the printed style of UUID/GUIDs by using another extension to %p. %pUb: 01020304-0506-0708-090a-0b0c0d0e0f10 %pUB: 01020304-0506-0708-090A-0B0C0D0E0F10 (upper case) %pUl: 04030201-0605-0807-090a-0b0c0d0e0f10 %pUL: 04030201-0605-0807-090A-0B0C0D0E0F10 (upper case) %pU defaults to %pUb Signed-off-by:

Makes use of skip_spaces() defined in lib/string.c for removing leading spaces from strings all over the tree. It decreases lib.a code size by 47 bytes and reuses the function tree-wide: text data bss dec hex filename 64688 584 592 65864 10148 (TOTALS-BEFORE) 64641 584 592 65817 10119 (TOTALS-AFTER) Also, while at it, if we see (*str && isspace(*str)), we can be sure to remove the first condition (*str) as the second one (isspace(*str)) also evaluates to 0 whenever *str == 0, making it redundant. In other words, "a char equals zero is never a space". Julia Lawall tried the semantic patch (http://coccinelle.lip6.fr) below, and found occurrences of this pattern on 3 more files: drivers/leds/led-class.c drivers/leds/ledtrig-timer.c drivers/video/output.c @@ expression str; @@ ( // ignore skip_spaces cases while (*str && isspace(*str)) { \(str++;\|++str;\) } | - *str && isspace(*str) ) Signed-off-by:

On the following sentence: while (*s && isspace(*s)) s++; If *s == 0, isspace() evaluates to ((_ctype[*s] & 0x20) != 0), which evaluates to ((0x08 & 0x20) != 0) which equals to 0 as well. If *s == 1, we depend on isspace() result anyway. In other words, "a char equals zero is never a space", so remove this check. Also, *s != 0 is most common case (non-null string). Fixed const return as noticed by Jan Engelhardt and James Bottomley. Fixed unnecessary extra cast on strstrip() as noticed by Jan Engelhardt. Signed-off-by: -

The difference between simple_strtoul() and simple_strtoull() is just the size of the variable used to keep track of the sum of characters converted to numbers: unsigned long simple_strtoul() {...} unsigned long long simple_strtoull(){...} Both are same size on my Core 2/gcc 4.4.1. Overflow condition is not checked on both functions, so an extremely large string can break these functions so that they don't even notice it. As we do not care for overflowing on these functions, always keep the sum using the larger variable around (unsigned long long) on simple_strtoull() and cast it to (unsigned long) on simple_strtoul(), which then becomes just a wrapper around simple_strtoull().

This patchset reduces lib/lib.a code size by 482 bytes on my Core 2 with gcc 4.4.1 even considering that it exports a newly defined function skip_spaces() to drivers: text data bss dec hex filename 64867 840 592 66299 102fb (TOTALS-lib.a-BEFORE) 64641 584 592 65817 10119 (TOTALS-lib.a-AFTER) and implements some code tidy up. Besides reducing lib.a size, it converts many in-tree drivers to use the newly defined function, which makes another small reduction on kernel size overall when those drivers are used. This patch: Change "<NULL>" to "(null)", unifying 3 equal strings. glibc also uses "(null)" for the same purpose. It decreases code size by 7 bytes: text data bss dec hex filename 15765 0 8 15773 3d9d vsprintf.o (ex lib/lib.a-BEFORE) 15758 0 8 15766 3d96 vsprintf.o (ex lib/lib.a-AFTER) Signed-off-by:

Restructure a bit for multiple version control systems support. Use a hash for each supported VCS that contains the commands and patterns used to find commits, logs, and signers. --git command line options are still used for hg except for --git-since. Use --hg-since instead. The number of commits can differ for git and hg, so --rolestats might be different. Style changes: Use common push style push(@foo...), simplify a return Bumped version to 0.23. Signed-off-by:

Fix email matching without name --n and --git-blame Using --non and --git-blame caused maintainer signature matching to fail. Fixed that by adding 3rd argument to sub format_email to control show/hide name portion of address Slurp -f file instead of reading line-by-line for K: pattern matching. Suggested by Wolfram Sang as more efficient Refactor git command execution Break into 2 functions, execute/analyze Share code between --git and --git-blame Don't warn multiple times when git isn't installed Improve stats reporting --git-min-percent and -- rolestats now count the total number of commits for either the period of --git-since or if using --git-blame the commits used by the current file and calculate commit % as # of commits signed / total commits * 100 Code style cleaning Use consistent sub foo { my (args...) = @_; Signed-off-by: -

The kernel offers with TIOCL_GETKMSGREDIRECT ioctl() the possibility to redirect the kernel messages to a specific console. However, since it's not possible to switch to the kernel message console after a panic(), it would be nice if the kernel would print the panic message on the current console. This patch series adds a new interface to access the global kmsg_redirect variable by a function to be able to use it in code where CONFIG_VT_CONSOLE is not set (kernel/panic.c). This patch: Instead of using and exporting a global value kmsg_redirect, introduce a function vt_kmsg_redirect() that both can set and return the console where messages are printed. Change all users of kmsg_redirect (the VT code itself and kernel/power.c) to the new interface. The main advantage is that vt_kmsg_redirect() can also be used when CONFIG_VT_CONSOLE is not set.

This is based on the old code in arch/x86/kernel/mfgpt_32.c, but is modular and not Geode-specific. There's no reason why the clock event device needs to be registered so early at boot; the clockevent code is perfectly capable of dynamic switching.

This is based on the old code on arch/x86/kernel/mfgpt_32.c, except it's not x86 specific, it's modular, and it makes use of a PCI BAR rather than a random MSR. Currently module unloading is not supported; it's uncertain whether or not it can be made work with the hardware. [akpm@linux-foundation.org: add X86 dependency] Signed-off-by:

Previously, OLPC support for the mic extensions was only enabled in the ALSA driver if CONFIG_OLPC and CONFIG_MGEODE_LX were both set. This was because the old geode GPIO code was written in a manner that assumed CONFIG_MGEODE_LX. With the new cs553x-gpio driver, this is no longer the case; as such, we can drop the requirement on CONFIG_MGEODE_LX and instead include a requirement on GPIOLIB. We use the generic GPIO API rather than the cs553x-specific API. Signed-off-by:

This creates a CS5535/CS5536 GPIO driver which uses a gpio_chip backend (allowing GPIO users to use the generic GPIO API if desired) while also allowing architecture-specific users directly (via the cs5535_gpio_* functions). Tested on an OLPC machine. Some Leemotes also use CS5536 (with a mips cpu), which is why this is in drivers/gpio rather than arch/x86. Currently, it conflicts with older geode GPIO support; once MFGPT support is reworked to also be more generic, the older geode code will be removed. Signed-off-by:

Use DECLARE_BITMAP(), find_first_zero_bit(), set_bit() and clear_bit() instead of rewriting code to do it with the minor number dynamic allocation bitmap.

If there's a failure creating the device (because there's already one with the same name, for example), the current implementation does not clear the bit for the allocated minor and that number is lost for future allocations. Second, the test currently in misc_deregister is broken, since it does not test for the 0 minor. Signed-off-by:
