This patchset improves KASAN reports by making them to have
call_rcu() call stack information. It is useful for programmers
to solve use-after-free or double-free memory issue.

prints up to 2 call_rcu() call stacks in KASAN report.
When call_rcu() is called, we store the call_rcu() call stack into

When wl12xx_cmd_role_disable() returns an error code,
a pairing runtime PM usage counter decrement is needed to
keep the counter balanced.

This loop in the error handling code should start a "i - 1" and end at
"i == 0". Currently it starts a "i" and ends at "i == 1". The result
is that it removes one attribute that wasn't created yet, and leaks the
zeroeth attribute.

Commit 9495b7e92f716ab2bd6814fab5e97ab4a39adfdd ("driver core: platform:
Initialize dma_parms for platform devices") in v5.7-rc5 causes
vb2_dma_contig_clear_max_seg_size() to kfree memory that was not
allocated by vb2_dma_contig_set_max_seg_size().

Preliminary discussion: https://lkml.org/lkml/2020/5/13/1327
This patch avoids introducing arch-specific trace points by leveraging
existing definition for ipi_raise.
Issues to address in potential future work:
- make ipi reason available on generic smp code level (possible?)
- addition of
pm_runtime_get_sync() increments the runtime PM usage counter even
the call returns an error code. Thus a pairing decrement is needed
on the error handling path to keep the counter balanced.
