lib: test_bitmap: add more start-end:offset/len tests There are inputs to bitmap_parselist() that would probably never be entered manually by a person, but might result from some kind of automated input generator. Things like ranges of length 1, or group lengths longer than nbits, overlaps, or offsets of zero. Adding these tests serve two purposes: 1) document what might seem odd but nonetheless valid input. 2) don't regress from what we currently accept as valid.

lib: test_bitmap: add more start-end:offset/len tests There are inputs to bitmap_parselist() that would probably never be entered manually by a person, but might result from some kind of automated input generator. Things like ranges of length 1, or group lengths longer than nbits, overlaps, or offsets of zero. Adding these tests serve two purposes: 1) document what might seem odd but nonetheless valid input. 2) don't regress from what we currently accept as valid.

bitmap_parse: Support 'all' semantics RCU code supports an 'all' group as a special case when parsing rcu_nocbs parameter. This patch moves the 'all' support to the core bitmap_parse code, so that all bitmap users can enjoy this extension. Moving 'all' parsing to a bitmap_parse level also allows users to pass patterns together with 'all' in regular group:pattern format, for example, "rcu_nocbs=all:1/2" would offload all the even-numbered CPUs regardless of the number of CPUs on the system.

lib: test_bitmap: clearly separate ERANGE from EINVAL tests. This block of tests was meant to find/flag incorrect use of the ":" and "/" separators (syntax errors) and invalid (zero) group len. However they were specified with an 8 bit width and 32 bit operations, so they really contained two errors (EINVAL and ERANGE). Promote them to 32 bit so it is clear what they are meant to target. Then we can add tests specific for ERANGE (no syntax errors, just doing 32bit op on 8 bit width, plus a typical 9-on-8 fencepost error).

lib/test_bitmap: test the tail after bitmap_to_arr64() Currently, test_bitmap_arr64() only tests bitmap_to_arr64()'s sanity by comparing the result of double-conversion (bm -> arr64 -> bm2) with the input bitmap. However, this may be not enough when one side hides bugs of the second one (e.g. tail clearing, which is being performed by both). Expand the tests and check the tail of the actual arr64 used as a temporary buffer for double-converting.

lib/test_bitmap.c: add optimisation tests Patch series "Bitmap optimisations", v2. These three bitmap patches use more efficient specialisations when the compiler can figure out that it's safe to do so. Thanks to Rasmus's eagle eyes, a nasty bug in v1 was avoided, and I've added a test case which would have caught it. This patch (of 4): This version of the test is actually a no-op; the next patch will enable it.
