2006-12-08[PATCH] Char: mxser_new, kill unneeded memsetsJiri Slaby
mxser_new, kill unneeded memsets There is no need to re-zero static global variables' memory, hence memsets doing this are useless. alloc_tty_struct also zeroes allocated memory: another candidate for removing. This fixes also a bug -- global structures are cleaned up after initialization of some its parts.

2006-12-08[PATCH] LOG2: Implement a general integer log2 facility in the kernelDavid Howells
This facility provides three entry points: ilog2() Log base 2 of unsigned long ilog2_u32() Log base 2 of u32 ilog2_u64() Log base 2 of u64 These facilities can either be used inside functions on dynamic data: int do_something(long q) { ...; y = ilog2(x) ...; } Or can be used to statically initialise global variables with constant values: unsigned n = ilog2(27); When performing static initialisation, the compiler will report "error: initializer element is not constant" if asked to take a log of zero or of something not reducible to a constant. They treat negative numbers as unsigned. When not dealing with a constant, they fall back to using fls() which permits them to use arch-specific log calculation instructions - such as BSR on x86/x86_64 or SCAN on FRV - if available.
