ad5b9d3a9e ANDROID: Fix compilation error when CPU_FREQ is disabled
The following compilation error can be observed when CONFIG_CPU_FREQ
is disabled, while CONFIG_ANDROID_VENDOR_HOOKS is enabled:

include/trace/hooks/cpufreq.h:14:18: warning: declaration of 'struct
cpufreq_policy' will not be visible outside of this function
[-Wvisibility] error, forbidden warning: cpufreq.h:14.

Include the cpufreq header in the cpufreq trace hooks header to
fix the compilation error.

51681321c0 ANDROID: fixup restricted hooks after tracepont refactoring
In upstream commit d9a1be1be3 ("tracepoints: Do not punish non
static call users"), tracepoint macros were refactored to optimize
for static_call() cases. Since the Android-specific restricted
vendor hook mechanism leverages tracehooks, this required
equivalent refactoring in include/trace/hooks/vendor_hooks.h

Like was done for the other non-upstream methods in
'struct ufs_hba_variant_ops', replace ->fill_prdt() with an Android
vendor hook.  This is considered to be better because it avoids any
conflicts with upstream changes to 'struct ufs_hba_variant_ops'.

Note that as a side effect of this change, fill_prdt is no longer
allowed to sleep.  That's fine for the only known use of this hook.

ae8ff465c5 ANDROID: vendor_hook: modify cpuidle vendor hook
When entering cluster-wide or system-wide power mode, Exynos cpu
power management driver checks the next hrtimer events of cpu
composing the power domain to prevent unnecessary attempts to enter
the power mode. Since struct cpuidle_device has next_hrtimer, it
can be solved by passing cpuidle device as a parameter of vh.

In order to improve responsiveness, it is necessary to prevent
entering the deep idle state in boosting scenario. So, vendor
driver should be able to control the idle state.

Due to above requirements, the parameters required for idle enter
and exit different, so the vendor hook is separated into
cpu_idle_enter and cpu_idle_exit.

We have debug infrastructure built on top of preempt/irq disable/enable
events. This requires modifications to the kernel tracing code. Since
this is not feasible with GKI, we started with registering to the
existing preemptirq trace events. However the performance of wide
variety of use cases are regressed as the rate of preemptirq events
is super high and generic trace events are slow.

Since GKI allows optimized trace events via restricted trace hooks,
add the same for preemptirq event.

4cc2f83c77 ANDROID: vendor_hooks: fix __section macro
After upstream 33def8498f ("treewide: Convert macro and uses of
__section(foo) to __section("foo")"), the preprocessor macro __section
now requires the section name to be double quoted.

This patch resolves breakage that results from merging down from
mainline in this out of tree header.

2f33651bdf ANDROID: GKI: fix up arguments for trace_android_vh_arch_set_freq_scale()
The 'cpus' parameter is now a constant pointer, so fix up the parameter
definition so that the build no longer breaks.

This was caused by upstream commit a20b7053b5 ("cpufreq,arm,arm64:
restructure definitions of arch_set_freq_scale()")

When a kernel panic occurred, it is sometimes caused by a other cpu
than the panic cpu. When a panic cpu sends smp stop IPI, it can help to
solve the problem even more if aonther cpu stores registers and
run cache flush.
