This commit documents the implicit RCU readers that are implied by the
this_cpu_inc() and atomic_long_inc() operations in __srcu_read_lock_fast()
and __srcu_read_unlock_fast(). While in the area, fix the documentation
of the memory pairing of atomic_long_inc() in __srcu_read_lock_fast().

92b7624fe052ffb0b7b70d96cd514e02e91664a8 | Analyze and fix the following issue in the Linux kernel code: KVM: arm64: Dump instruction on hyp panic | Problem Details:
Similar to the kernel panic, where the instruction code is printed,
we can do the same for hypervisor panics.
This patch does that only in case of “CONFIG_NVHE_EL2_DEBUG” or nvhe.
The next patch adds support for pKVM.
Also, remove the hardcoded argument dump_kernel_instr().
