When a memory device, such as CXL1.1 type3 memory, is emulated as
normal memory (E820_TYPE_RAM), the memory device is indistinguishable
from normal DRAM in terms of memory tiering with the current implementation.

This commit replaces riscv's support for FTRACE_WITH_REGS with support
for FTRACE_WITH_ARGS. This is required for the ongoing effort to stop
relying on stop_machine() for RISCV's implementation of ftrace.
The main relevant benefit that this change will bring for the above
use-case is that now we d
Currently most of the API for page_frag API is returning
'virtual address' as output or expecting 'virtual address'
as input, in order to differentiate the API handling between
'virtual address' and 'struct page', add '_va' suffix to the
corresponding API mirroring the page_pool_alloc_va() API of
