When gpio detection is not supplied, presence state transitions depend
on every smbus transfer result from get_property(). This patch tries to
check battery presence again with well supported command before
state transition.

The "managed_irq" for isolcpus is supported after the commit

Transfer all previous tests for KASAN to KUnit so they can be run
more easily. Using kunit_tool, developers can run these tests with their
other KUnit tests and see "pass" or "fail" with the appropriate KASAN
report instead of needing to parse each KASAN report to test KASA
The proposed KUnit test naming guidelines[1] suggest naming KUnit test
modules [suite]_kunit (and hence test source files [suite]_kunit.c).
Rename test_kunit.c to kasan_kunit.c to comply with this, and be
consistent with other KUnit tests.
[1]:
https://lore.kernel.org/linux-kselftest/20200702071
KASAN errors will currently trigger a panic when panic_on_warn is set.
This renders kasan_multishot useless, as further KASAN errors won't be
reported if the kernel has already paniced. By making kasan_multishot
disable this behaviour for KASAN errors, we can still have the benefits
of panic_on_war

Before entering a guest, we need to set the HDEC to pull us out again
when the guest's time is up. This needs some care, though, because the
HDEC is edge triggered, which means that if it expires before entering the
guest, the interrupt will be lost, meaning we stay in the guest
indefinitely (in p
There is no need to jump to the "out" tag when "ret < 0", just return
directly to "ret".

Ftrace has ability to export trace packets to other destination.
Currently, only function trace can be exported. This series extends the
support to event trace and trace_maker. STM is one possible destination to

We will support copying event trace to STM. Change
STM_SOURCE_FTRACE to depend on TRACING since we will

Which exact 'cmd' is it here?
I _guess_ it is one of those uninitialized in set_arglen[], which is 0.
But if that is the case, should it be initialized t
More traces like event trace or trace marker will be supported.
Add flag for difference traces, so that they can be controlled
separately. Move current function trace to it's own flag
instead of global ftrace enable flag.

Only function traces can be exported to other destinations currently.
This patch exports event trace as well. Move trace export related
function to the beginning of file so other trace can call
trace_process_export() to export.

By profiling f2fs compression works, I've found vmap() callings are
bottlenecks of f2fs decompression path. Changing these with
vm_map_ram(), we can enhance f2fs decompression speed pretty much.
