Modpost: fixed USB alias generation for ranges including 0x9 and 0xA

2014-02-22T21:32:28+00:00

commit 03b56329f9bb5a1cb73d7dc659d529a9a9bf3acc upstream. Commit afe2dab4f6 ("USB: add hex/bcd detection to usb modalias generation") changed the routine that generates alias ranges. Before that change, only digits 0-9 were supported; the commit tried to fix the case when the range includes higher values than 0x9. Unfortunately, the commit didn't fix the case when the range includes both 0x9 and 0xA, meaning that the final range must look like [x-9A-y] where x <= 0x9 and y >= 0xA -- instead the [x-9A-x] range was produced. Modprobe doesn't complain as it sees no difference between no-match and bad-pattern results of fnmatch(). Fixing this simple bug to fix the aliases. Also changing the hardcoded beginning of the range to uppercase as all the other letters are also uppercase in the device version numbers. Fortunately, this affects only the dvb-usb-dib0700 module, AFAIK. Signed-off-by: Jan Moskyto Matejka Signed-off-by: Greg Kroah-Hartman

scripts/link-vmlinux.sh: only filter kernel symbols for arm

2014-01-09T20:25:09+00:00

commit 7122c3e9154b5d9a7422f68f02d8acf050fad2b0 upstream. Actually CONFIG_PAGE_OFFSET isn't same with PAGE_OFFSET, so it isn't easy to figue out PAGE_OFFSET defined in header file from scripts. Because CONFIG_PAGE_OFFSET may not be defined in some ARCHs( 64bit ARCH), or defined as bogus value in !MMU case, so this patch only applys the filter on ARM when CONFIG_PAGE_OFFSET is defined as the original problem is only on ARM.

scripts/kallsyms: filter symbols not in kernel address space

2013-11-01T22:43:02+00:00

This patch uses CONFIG_PAGE_OFFSET to filter symbols which are not in kernel address space because these symbols are generally for generating code purpose and can't be run at kernel mode, so we needn't keep them in /proc/kallsyms. For example, on ARM there are some symbols which may be linked in relocatable code section, then perf can't parse symbols any more from /proc/kallsyms, this patch fixes the problem (introduced b9b32bf70f2fb710b07c94e13afbc729afe221da) Cc: Russell King Cc: linux-arm-kernel@lists.infradead.org Cc: Michal Marek Signed-off-by: Ming Lei Signed-off-by: Rusty Russell Cc: stable@vger.kernel.org

Pull kconfig fix from Michal Marek: "This is a fix for a regression caused by my previous pull request. A sed command in scripts/config that used colons as separator was accidentally changed to use slashes, which fails when you use slashes in a value. Changing it back to colons is of course not a proper fix, but at least it will be broken in the same way it had been for four years. A proper fix is pending" * 'kconfig' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild: scripts/config: fix variable substitution command

checkpatch: add test for positional misuse of section specifiers like __initdata

2013-09-11T22:58:49+00:00

As discussed recently on the arm [1] and lm-sensors [2] lists, it is possible to use section markers on variables in a way which gcc doesn't understand (or at least not the way the developer intended): static struct __initdata samsung_pll_clock exynos4_plls[nr_plls] = { does NOT put exynos4_plls in the .initdata section. The __initdata marker can be virtually anywhere on the line, EXCEPT right after "struct". The preferred location is before the "=" sign if there is one, or before the trailing ";" otherwise. [1] http://permalink.gmane.org/gmane.linux.ports.arm.kernel/258149 [2] http://lists.lm-sensors.org/pipermail/lm-sensors/2013-August/039836.html So, update checkpatch to find these misuses and report an error when it's immediately after struct or union, and a warning when it's otherwise not immediately before the ; or =.

checkpatch: reduce runtime/cpu time used

2013-09-11T22:58:48+00:00

There are some cases where checkpatch can take a long time to complete. Reduce the likelihood of this long run-time by adding a new test for lines with and without comments and eliminating checks on lines with only comments. This reduces the number of "ctx_statement_block" calls, and also the number of tests of $stat, which is now undefined for these blank lines. One test in particular, the "check for switch/default statements without a break", could take an extremely long time to parse as it tries to skip interleaving comments within the ctx_statement_block/$stat and that could be done multiple times unnecessarily. A small test case taken from cfg80211.h before this patch would take 1000's of seconds to run, now it's just a couple seconds.
