After LLVM rG9e33c096476a ("[ELF] Keep orphan section names
(.rodata.foo .text.foo) unchanged if !hasSectionsCommand"), LLD splits
compound literals to separate sections with -fdata-sections, which
it always enables with LTO. Merge these sections to allow LLVM to be
upgraded.

Allwinner's SoC timer driver (timer-sun4i.c) has to be built-in rather
than modularized for the following limitations in linux timer framework:
1. tick broadcast installed by insmod cannot switch to oneshot mode
correctly
2. cpus cannot enter cpuidle state due to the issue above.
3. rcu warnings will appear if we forcibly re-enable tick-broadcast
for each cpu when new tick broadcast device is installed by insmod
(timer-sun4i.c in our case)

Access to the AMU counters should be disabled by default in kvm guests,
as information from the counters might reveal activity in other guests
or activity on the host.
Therefore, disable access to AMU registers from EL0 and EL1 in kvm
guests by:
- Hiding the presence of the extension in the feature register
(SYS_ID_AA64PFR0_EL1) on the VCPU.
- Disabling access to the AMU registers before switching to the guest.
- Trapping accesses and injecting an undefined instruction into the
guest.

The activity monitors extension is an optional extension introduced
by the ARMv8.4 CPU architecture. In order to access the activity
monitors counters safely, if desired, the kernel should detect the
presence of the extension through the feature register, and mediate
the access.
Therefore, disable direct accesses to activity monitors counters
from EL0 (userspace) and trap them to EL1 (kernel).
To be noted that the ARM64_AMU_EXTN kernel config does not have an
effect on this code. Given that the amuserenr_el0 resets to an
UNKNOWN value, setting the trap of EL0 accesses to EL1 is always
attempted for safety and security considerations. Therefore firmware
should still ensure accesses to AMU registers are not trapped in
EL2/EL3 as this code cannot be bypassed if the CPU implements the
Activity Monitors Unit.

When changing to use suspend-to-idle to save power, the PMIC irq can not
wakeup the system due to lack of wakeup capability, which will cause
the sub-irqs (such as power key) of the PMIC can not wake up the system.
Thus we can add the wakeup capability for PMIC irq to solve this issue,
as well as removing the IRQF_NO_SUSPEND flag to allow PMIC irq to be
a wakeup source.

Suspend to IDLE invokes tick_unfreeze() on resume. tick_unfreeze() on the
first resuming CPU resumes timekeeping, which also has the side effect of
resetting the softlockup watchdog on this CPU.
But on the secondary CPUs the watchdog is not reset in the resume /
unfreeze() path, which can result in false softlockup warnings on those
CPUs depending on the time spent in suspend.
Prevent this by clearing the softlock watchdog in the unfreeze path also
on the secondary resuming CPUs.
