Hi Leo,
I think there is an issue here in that your modification assumes that
all cpus in the system are of the same ETM type. The original routine
allowed for differing ETM types, thus differing cpu ETM field lengths

VMCI queue pair allocation is disabled, if a VM is in FT mode. In
these cases, VMware Tools may still once in a while attempt to

This is a set of improvements for the rtc-s5m driver. The first patch
is new in v4: I noticed the I2C regmap is not selected by this driver's
Kconfig. Two subsequent patches were already submitted separately.

Use the managed variant of i2c_new_dummy_device() to shrink code and

Right now, we only check against MAX_PHYSMEM_BITS - but turns out there
are more restrictions of which memory we can actually hotplug, especially
om arm64 or s390x once we support them: we might receive something like
