kbuild: set correct KBUILD_MODNAME when using well known kernel symbols as module names
This patch fixes a problem when we use well known kernel symbols as module names. For example, if module source name is current.c, idle_stack.c or etc., we have a bad KBUILD_MODNAME value. For example, KBUILD_MODNAME will be "get_current()" instead of "current", or "(init_thread_union.stack)" instead of "idle_task". The trick is to define a stringify macro on the commandline - named KBUILD_STR for namespace reasons - and then to stringify the module name. There are a few uses of KBUILD_MODNAME throughout the tree but the usage is for debug and will not be harmed by this change so left untouched for now. While at it KBUILD_BASENAME was changed too. Any spinlock usage in the unix module would have created wrong section names without it. Usage in spinlock.h fixed so it no longer stringify KBUILD_BASENAME. Original patch from Ustyogov Roman - all bugs introduced by me. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
