QDSS components depend on "CONFIG_CORESIGHT", so enable it.
Enable "STM_PROTO_BASIC“ to support to write log to /dev/coresight-stm.

Memlat and compute governors are made immutable to avoid governor
switch at run time as the devices using these governors are tightly
coupled with hardware features. These governors allocate pmu counters
to count various events used in the algorithm. These counters are
allocated exclusively for algorithm's use.
This leaves limited counters available for other uses in the system
such as profiling in user space using perf tool. Add and export a
function in devfreq memlat governor to remove immutable flag to allow
governor switch, which in turn can free pmu counters.
Similarly add and export a function in rimps_memlat driver to
free pmu counters.
The intended use of these functions is to be called by test modules
to allow freeing of pmu counters at runtime.

set_event will return NULL if event_id is not valid, the
caller is proceeding further without proper check for NULL.
Update pmu event setup function to check pevent for NULL.
From the RIMPS perspective, pmu counter IDs 0 and 1 correspond
to 64bit cycle counter with ID 0 representing low 32 bit and
ID 1 representing high 32bit, while the counter IDs from 2 to 7
correspond to remaining PMUs. At the time of storing pmu counter
values to RIMPS shared memory, the function store_event_val()
stores both low and high 32bit values of cycle counter when ID 0 is
passed as argument to pmu index, hence no need to handle ID 1
separately. Update logic accordingly to drop check for ID 1.

Commit 3bb697514e ("usb: dwc3: Add support for nominal
elastic buffer") breaks working of current 5.4 kernel
based targets by clearing elastic buffer which is not
expected. Hence revert the change.

If we want to disable clocks but still keep the link active, both
ref_clk and core_clk_unipro should be skipped.
Commit 284fa080cb5f ("scsi: ufs: fix broken hibern8_on_idle sysfs
nodes") is the original change from msm-4.14. We pick it up to msm-5.4
due to upstream missed this change. To follow GKI policy on 5.4, we
simplifed it and kept parameters name to avoid breaking ABI.

Use the exported function instead of kallsyms_lookup to get
log_buf size, this can save a lot of time during boot up.

In older kernel target we had ICB and it use to take input
in BCM units for QUP core path, whereas in recent kernel we
have ICC for BW NOC voting and it accept input in KHz.
So correct unit for ICC optimization code.

There is a race during page offline that can lead to infinite loop:
a page never ends up on a buddy list and __offline_pages() keeps
retrying infinitely or until a termination signal is received.
Thread#1 - a new process:
load_elf_binary
begin_new_exec
exec_mmap
mmput
exit_mmap
tlb_finish_mmu
tlb_flush_mmu
release_pages
free_unref_page_list
free_unref_page_prepare
set_pcppage_migratetype(page, migratetype);
// Set page->index migration type below MIGRATE_PCPTYPES
Thread#2 - hot-removes memory
__offline_pages
start_isolate_page_range
set_migratetype_isolate
set_pageblock_migratetype(page, MIGRATE_ISOLATE);
Set migration type to MIGRATE_ISOLATE-> set
drain_all_pages(zone);
// drain per-cpu page lists to buddy allocator.
Thread#1 - continue
free_unref_page_commit
migratetype = get_pcppage_migratetype(page);
// get old migration type
list_add(&page->lru, &pcp->lists[migratetype]);
// add new page to already drained pcp list
Thread#2
Never drains pcp again, and therefore gets stuck in the loop.
The fix is to try to drain per-cpu lists again after
check_pages_isolated_cb() fails.
