Doesn't save and restore ETMs state while CPU being offline and
online hot-plug. Since ETM driver can save and restore ETMs state
in hot-plug process. If JTAG driver save and restore ETMs state
as well, there could be some conflicts with ETM driver.

When a secure system heap buffer is freed, the buffer's heap pointer
is changed to the system heap, so that the buffer's pages can be freed
into the secure pools properly. However, the buffer's heap pointer
is not reset back to the secure system heap after the buffer has been
freed.
This is problematic, as the ION buffer tracking code uses the buffer's
heap pointer to figure out which heap's memory accounting stats it has
to decrement when a buffer is freed. In this case, we end up not
decrementing the system secure heap's memory accounting stats, but
instead, decrement the system heap's accounting stats, which is not
correct.
After freeing a buffer's pages, restore the buffer's heap pointer to
the secure system heap, to ensure that the correct heap's accounting
stats are adjusted.

The number of PCIe PARF testbus signals available varies for each

during a PARF dump, add support to define how many PCIe PARF
testbus selectors are provided.

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.
