This started with a patch that enabled `clippy::ptr_as_ptr`. Benno
Lossin suggested I also look into `clippy::ptr_cast_constness` and I
discovered `clippy::as_ptr_cast_mut`. This series now enables all 3
lints. It also enables `clippy::as_underscore` which ensures other
pointer casts weren't missed. The first commit reduces the need for
pointer casts and is shared with another series[1].
As a later addition, `clippy::cast_lossless` and `clippy::ref_as_ptr`
are also enabled.

When compiling the RTC library functions test as a module, the module
has the non-descriptive name "lib_test.ko". Fix this by adding the
subsystem's name as a prefix.

2.43.0
This series introduces support in the KVM and ARM PMUv3 driver for
partitioning PMU counters into two separate ranges by taking advantage
of the MDCR_EL2.HPMN register field.
The advantage of a partitioned PMU would be to allow KVM guests direct
access to a subset of PMU functionality, greatly reducing the overhead
of performance monitoring in guests.
While this feature could be accepted on its own merits, practically
there is a lot more to be done before it will be fully useful, so I'm
sending as an RFC for now.
v3:
* Include cpucap definition for FEAT_HPMN0 to allow for setting HPMN
to 0
* Include PMU header cleanup provided by Marc [1] with some minor
changes so compilation works
* Pull functions out of pmu-emul.c that aren't specific to the
emulated PMU. This and the previous item aren't strictly
needed but they provide a nicer starting point.
* As suggested by Oliver, start a file for partitioned PMU functions
and move the reserved_host_counters parameter and MDCR handling into
KVM so the driver does not have to know about it and we need fewer
hacks to keep the driver working on 32-bit ARM. This was not a
complete separation because the driver still needs to start and stop
the host counters all at once and needs to toggle MDCR_EL2.HPME to
do that. Introduce kvm_pmu_host_counters_{enable,disable}()
functions to handle this and define them as no ops on 32-bit ARM.
* As suggested by Oliver, don't limit PMCR.N on emulated PMU. This
value will be read correctly when the right traps are disabled to
use the partitioned PMU
