2012-09-21staging: usbip: stub_dev: Fixed oops during removal of usbip_hostnavin
stub_shutdown_connection() should set kernel thread pointers to NULL after killing them. so that at the time of usbip_host removal stub_shutdown_connection() doesn't try to kill kernel threads which are already killed.

2012-09-21perf tools: Fix parallel buildEric Sandeen
Parallel builds of perf were failing for me on a 32p box, with: * new build flags or prefix util/pmu.l:7:23: error: pmu-bison.h: No such file or directory ... make: *** [util/pmu-flex.o] Error 1 make: *** Waiting for unfinished jobs.... This can pretty quickly be seen by adding a sleep in front of the bison calls in tools/perf/Makefile and running make -j4 on a smaller box i.e.: sleep 10; $(QUIET_BISON)$(BISON) -v util/pmu.y -d -o $(OUTPUT)util/pmu-bison.c Adding the following dependencies fixes it for me.

2012-09-21x86/kbuild: archscripts depends on scripts_basicJeff Mahoney
While building the SUSE kernel packages, which build the scripts, make clean, and then build everything, we have been running into spurious build failures. We tracked them down to a simple dependency issue: $ make mrproper CLEAN arch/x86/tools CLEAN scripts/basic $ cp patches/config/x86_64/desktop .config $ make archscripts HOSTCC arch/x86/tools/relocs /bin/sh: scripts/basic/fixdep: No such file or directory make[3]: *** [arch/x86/tools/relocs] Error 1 make[2]: *** [archscripts] Error 2 make[1]: *** [sub-make] Error 2 make: *** [all] Error 2 This was introduced by commit 6520fe55 (x86, realmode: 16-bit real-mode code support for relocs), which added the archscripts dependency to archprepare.

2012-09-21firmware: fix directory creation rule matching with make 3.80Mark Asselstine
Since make 3.80 doesn't support secondary expansion it uses a fallback rule to create firmware directories which is matched after primary expansion of the $(installed-fw) rule's prerequisite. Commit 6c7080a61fc7 [firmware: fix directory creation rule matching with make 3.82] changed the expression generated after primary expansion such that the fallback was not matched. Updating the fallback rule to match the new look primary expansion is not an option for various reasons. The trailing slash added here to $(INSTALL_FW_PATH)/. while defining installed-fw-dirs fixes builds with make 3.82 since this will provide a matching rule for $(INSTALL_FW_PATH)/$$(dir %) when % is in the base firmware directory (ie. $(dir %) gives './'). Versions of make prior to 3.82 will strip this trailing slash along with the one generated by $(dir %) when % is in the base firmware directory and as such continue to function as before.
