Some additional synchronization is needed on Android ARM64; we see a

Inspired by [1], move the page fragment allocator from page_alloc
into its own c file and header file, as we are about to make more
change for it to replace another page_frag implementation in
sock.c
As this patchset is going to replace 'struct page_frag' with
'struct page_frag_cache' in sched.h,

Currently we generate notifyids in the linux kernel and override
those found in rsc_table.
This doesn't play well with users expecting to use the exact ids
from rsc_table.
So, use predefined notifyids found in rsc_table if any. Otherwise,
let Linux generate the ids as before.
Keypoint is we also
The testing is done by ensuring that the fragment allocated
from a frag_frag_cache instance is pushed into a ptr_ring
instance in a kthread binded to a specified cpu, and a kthread
binded to a specified cpu will pop the fragment from the
ptr_ring and free the fragment.

Currently, the rproc "atomic_t power" variable is incremented during:
a. WPSS rproc auto boot.
b. AHB power on for ath11k.
During AHB power off (rmmod ath11k_ahb.ko), rproc_shutdown fails

Introduce a new kselftest to identify slowdowns in key boot events.
This test uses ftrace to monitor the start and end times, as well as
the durations of all initcalls, and compares these timings to reference
