The i.MX SCU soc driver depends on SCU firmware driver, so it has to
use platform driver model for proper defer probe operation, since
it has no device binding in DT file, a simple platform device is
created together inside the platform driver. To make it more clean,
we can just move the entire SCU

Hello,
This series mainly adds sama5d2 support where we need to avoid using
clock index 0 because that clock is never enabled by the driver.
There is also a rework of the 32khz clock handling so it is not used for
clockevents on 32 bit counter because the increased rate improves the
resolution an
Stop using the slow clock as the clock source for 32 bit counters because
even at 10MHz, they are able to handle delays up to two minutes. This
provides a way better resolution.

Hi,

that several checks under CONFIG_SLAB_FREELIST_HARDENED weren't being

adding a simple double-free test for SLAB.

NVIDIA haven't made any changes to arm,mmu-500. It is only used in different
topology. New model would be mis-leading here.
As suggested by Robin, It can just be moved to
rr (https://rr-project.org, https://arxiv.org/abs/1705.05937) grapples
with a similar problem. We need to intercept commonly-executed system
calls and wrap them with our own processing, with minimal overhead. I
think our basic approach might work for Wine without kernel changes.
We use SECCOMP_SET
Thanks for the heads up Oliver -- I will send a patch with a comment on this.

Hi,
here is small series to follow-up on the review comments for moving
the kvm-amd module code to its own sub-directory. The comments were
only about renaming structs and symbols, so there are no functional
changes in these patches.
