Subject: [PATCHv2 10/11] atomics: switch to generated instrumentation
As a step towards ensuring the atomic* APIs are consistent, let's switch
to wrappers generated by gen-atomic-instrumented.h, using the same table
used to generate the fallbacks and atomic-long wrappers.
These are checked in rather than generated with Kbuild, since:
* This allows inspection of the atomics with git grep and ctags on a
pristine tree, which Linus strongly prefers being able to do.
* The fallbacks are not expected to change very often, and are not
affected by machine details or configuration options, so regenerating
them for *every* build is somewhat wasteful.
* These are included by files required *very* early in the build process
(e.g. for generating bounds.h), and we'd rather not complicate the
top-level Kbuild file.
Generating the atomic headers means that the instrumented wrappers will
remain in sync with the rest of the atomic APIs, and we gain all the
ordering variants of each atomic without having to manually expaned them
all.
The KASAN checks are automatically generated based on the function
parameters defined in atomics.tbl. Note that try_cmpxchg() now correctly
treats 'old' as a parameter that may be written to, and not only read as
the hand-written instrumentation assumed.
Other than the change to try_cmpxchg(), existing code should not be
affected by this patch. The patch instruoduces instrumentation for all
optional atomics (and ordering variants), along with the ifdeffery this
requires, enabling other archtiectures to make use of the instrumented
atomics.
