Evaluate the register before the asm section so that the C compiler
generates warnings when there is an issue with the register argument.
This will prevent possible future issues such as the one seen here [1]
where a missing bracket caused the shift and addition operators to be
evaluated in the wrong order, but no warning was emitted. The GNU
assembler has no warning for when expressions evaluate differently to C
due to different operator precedence, but the C compiler has some
warnings that may suggest something is wrong. For example in this case
the following warning would have been emitted:
error: operator '>>' has lower precedence than '+'; '+' will be evaluated first [-Werror,-Wshift-op-parentheses]
There are currently no existing warnings that need to be fixed.

According to the gcc manual functions "whose return value is not
affected by changes to the observable state of the program and that have
no observable effects on such state other than to return a value may
lend themselves to optimizations such as common subexpression
elimination. Declaring such functions with the 'const' attribute allows
GCC to avoid emitting some calls in repeated invocations of the function
with the same argument values."

For i.MX8MP, we cannot ensure that cycle counter overflow occurs at least
4 times as often as other events. Due to byte counters will count for any
event configured, it will overflow more often. And if byte counters
overflow that related counters would stop since they share the
COUNTER_CNTL. We can speed up cycle counter overflow frequency by setting
counter parameter (CP) field of cycle counter. In this way, we can avoid
stop counting byte counters when interrupt didn't come and the byte
counters can be fetched or updated from each cycle counter overflow
interrupt.
Because we initialize CP filed to shorten counter0 overflow time, the cycle
counter will start couting from a fixed/base value each time. We need to
remove the base from the result too. Therefore, we could get precise result
from cycle counter.

[ 84.195923] Chain exists of:

[ 84.238237] lock(dmc620_pmu_irqs_lock);
[ 84.242236]
*** DEADLOCK ***
The following locking order happens when dmc620_pmu_get_irq() calls
cpuhp_state_add_instance_nocalls().
lock(dmc620_pmu_irqs_lock) --> lock(cpu_hotplug_lock)
On the other hand, the calling sequence
cpuhp_thread_fun()
=> cpuhp_invoke_callback()
=> dmc620_pmu_cpu_teardown()
leads to the locking sequence
lock(cpuhp_state-down) => lock(dmc620_pmu_irqs_lock)
Here dmc620_pmu_irqs_lock protects both the dmc620_pmu_irqs and the
pmus_node lists in various dmc620_pmu instances. dmc620_pmu_get_irq()
requires protected access to dmc620_pmu_irqs whereas
dmc620_pmu_cpu_teardown() needs protection to the pmus_node lists.
Break this circular locking dependency by using two separate locks to
protect dmc620_pmu_irqs list and the pmus_node lists respectively.

Commit fb08a1908c ("dax: simplify the dax_device <-> gendisk
association") introduced new logic for gendisk association, requiring
drivers to explicitly call dax_add_host() and dax_remove_host().
For dcssblk driver, some dax_remove_host() calls were missing, e.g. in
device remove path. The commit also broke error handling for out_dax case
in device add path, resulting in an extra put_device() w/o the previous
get_device() in that case.
This lead to stale xarray entries after device add / remove cycles. In the
case when a previously used struct gendisk pointer (xarray index) would be
used again, because blk_alloc_disk() happened to return such a pointer, the
xa_insert() in dax_add_host() would fail and go to out_dax, doing the extra
put_device() in the error path. In combination with an already flawed error
handling in dcssblk (device_register() cleanup), which needs to be
addressed in a separate patch, this resulted in a missing device_del() /
klist_del(), and eventually in the kernel crash with list_add corruption on
a subsequent device_add() / klist_add().
Fix this by adding the missing dax_remove_host() calls, and also move the
put_device() in the error path to restore the previous logic.

architecture specific definitions.
This patch moves out arch specific header from util/perf_regs.h for
generalizing the 'util' folder, as a result, the source files in 'arch'
folder explicitly include architecture's perf_regs.h.

The macros PERF_REGS_MAX and PERF_REGS_MASK are architecture specific,
let's remove them from the common file util/perf_regs.c.
As a side effect, the weak functions arch__intr_reg_mask() and
arch__user_reg_mask() just return zeros, every arch defines its own
functions in the 'arch' folder for returning right values.
Note, we don't need to return intr/user register masks dynamically, this
is because these two functions are invoked during recording phase but
not decoding phase, they are always invoked on the native environment,
thus we don't need to parse them dynamically.
