Reuse library function for kernel code #93

Closed myaut closed 10 years ago

myaut commented 10 years ago

Replace init_seg from kernel/start.c with memset/memcpy Original init_seg are not optimized. Since current development tree contains optimized memset and memcpy functions, they could be used for copying segments or zeroing BSS segments in kernel/start.c or loader code.
Replace thread_map_search with bsearch

rampant1018 commented 10 years ago

I can't replace thread_map_search with bsearch. Because thread_map_search will search upper bound in map array, bsearch can just search element which matches key in map array. Is something I missed?

myaut commented 10 years ago

Yes, thread_map_search implementation is a bit different from binary search. Thanks for you work.
