During floating point and vector save to thread data fr0/vs0 are clobbered
by the FPSCR/VSCR store routine. This leads to userspace register corruption
and application data corruption / crash under the following rare condition:
* A userspace thread is executing with VSX/FP mode enabled
* The us

And "biops" to "bitops"? :-)

Has it been considered to add kunit tests for the new functions?
Thanks,
Bart.

There is a typo in the subject: shouldn't "atomig" be changed
into "atomic"?
Thanks,
Bart.
Add helpers around test_and_{set,clear}_bit() that allow to search for
clear or set bits and flip them atomically.
The target patterns may look like this:
for (idx = 0; idx < nbits; idx++)
if (test_and_clear_bit(idx, bitmap))
do_something(idx);
Or

After removal of the legacy eeprom driver the only remaining I2C
client device driver supporting I2C_CLASS_SPD is jc42. Because this
driver also supports I2C_CLASS_HWMON, adapters don't have to
declare support for I2C_CLASS_SPD if they support I2C_CLASS_HWMON.
It's one step towards getting rid of I

When you have to list different thin
The asm-generic/io.h already has default definition, remove unnecessary
arch's defination.
