module: Replace kmap() with kmap_local_page() (2022-07-20 14:27:46 -0700)
----------------------------------------------------------------
Modules updates for 6.0
For the 6.0 merge window the modules code shifts to cleanup and minor fixes
effort. This is becomes much easier to do and review now due to the code
split to its own directory from effort on the last kernel release. I expect
to see more of this with time and as we expand on test coverage in the future.
The cleanups and fixes come from usual suspects such as Christophe Leroy and
Aaron Tomlin but there are also some other contributors.
One particular minor fix worth mentioning is from Helge Deller, where he spotted
a *forever* incorrect natural alignment on both ELF section header tables:
* .altinstructions
* __bug_table sections
A lot of back and forth went on in trying to determine the ill effects of this
misalignment being present for years and it has been determined there should
be no real ill effects unless you have a buggy exception handler. Helge actually
hit one of these buggy exception handlers on parisc which is how he ended up
spotting this issue. When implemented correctly these paths with incorrect
misalignment would just mean a performance penalty, but given that we are
dealing with alternatives on modules and with the __bug_table (where info
regardign BUG()/WARN() file/line information associated with it is stored)
this really shouldn't be a big deal.
The only other change with mentioning is the kmap() with kmap_local_page()
and my only concern with that was on what is done after preemption, but the
virtual addresses are restored after preemption. This is only used on module
decompression.
This all has sit on linux-next for a while except the kmap stuff which has
been there for 3 weeks.
