tprof_lock is not a spin mutex. use mutex_{enter,exit}(). oops
Explicitly disable overflow interrupts before enabling the cycle counter.
PMCR_EL0.LC should be set. ARM deprecates use of PMCR_EL0.LC=0
Even if an overflow interrupt is occured for a counter outside tprof management,
the bit of onverflow status register must be cleared to prevent an interrupt storm.

Improve tprof(4) - Multiple events can now be handled simultaneously. - Counters should be configured with TPROF_IOC_CONFIGURE_EVENT in advance, instead of being configured at TPROF_IOC_START. - The configured counters can be started and stopped repeatedly by PROF_IOC_START/TPROF_IOC_STOP. - The value of the performance counter can be obtained at any timing as a 64bit value with TPROF_IOC_GETCOUNTS. - Backend common parts are handled in tprof.c as much as possible, and functions on the tprof_backend side have been reimplemented to be more primitive. - The reset value of counter overflows for profiling can now be adjusted. It is calculated by default from the CPU clock (speed of cycle counter) and TPROF_HZ, but for some events the value may be too large to be sufficient for profiling. The event counter can be specified as a ratio to the default or as an absolute value when configuring the event counter. - Due to overall changes, API and ABI have been changed. TPROF_VERSION and TPROF_BACKEND_VERSION were updated.

PMCR.E should not be disabled from tprof. PMCR.E controls not only performance event counters but also the cycle counter operation, and the cycle counter may be used for cpu_counter. Similarly, the 31st bit in PMINTENCLR and PMCNTENCLR controls the cycle counter, not performance event counters, and should not be modified.
