[RFC v9 1/1] mconf: global i-search in menu prompts

Some menus in the kernel configuration are rather large and it can be time-consuming for a user to navigate through several menu items to reach the menu entry that he wants to modify -- for users with less than 100% healthy eyes, this process can also be challenging. An i-search functionality coul

[PATCH 1/2] perf: drop unneeded bitmap_zero() in util/header.c

On top of next-20180622. bitmap_zero() is called after bitmap_alloc() in perf code. But bitmap_alloc() internally uses calloc() which guarantees that allocated area is zeroed. So following bitmap_zero is unneeded. Drop it. This happened because of confusing name for bitmap allocator. It should ha
