291f93ca33 lib: test_bitmap: add bitmap_print_bitmask/list_to_buf test cases 
The added test items cover both cases where bitmap buf of the printed
result is greater than and less than 4KB.
And it also covers the case where offset for printing is non-zero
which will happen when printed buf is larger than one page in
sysfs bin_attribute.

b18def121f 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.

These are copies of existing tests, with just 31 --> N.  This ensures
the recently added "N" alias transparently works in any normally

97330db3af 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.

Add tests that specify a valid range, but one that is outside the

494215fbf2 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).

809e308f7f lib: new testcases for bitmap_parse{_user} 
New version of bitmap_parse() is unified with bitmap_parse_list(),
and therefore:

- weakens rules on whitespaces and commas between hex chunks;

- in addition to

- allows passing UINT_MAX or any other big number as the length of input
  string instead of actual string length.

The patch covers the cases.

17b6753ff0 lib/test_bitmap: force argument of bitmap_parselist_user() to proper address space 
Patch series "gpio: pca953x: Convert to bitmap (extended) API", v2.

While converting gpio-pca953x driver to bitmap API, I noticed that we
have no function to replace bits.

So, that's how patch 7 appears.

First 6 patches are preparatory of the test suite (including some
warning fixes, etc).

Patches 8-9 are preparatory for the GPIO driver to be easier converted
to bitmap API, conversion to which happens in patch 10.

Patch 11 contains simple indentation fixes.

This patch (of 11):

Sparse complains:

  lib/test_bitmap.c:345:58: warning: incorrect type in argument 1 (different address spaces)
  lib/test_bitmap.c:345:58:    expected char const [noderef] <asn:1> *ubuf
  lib/test_bitmap.c:345:58:    got char const *const in
