This patchset adds soft dirty and userfaultfd write protect tracking support
for RISC-V.
As described in the patches, we are trying to utilize only one free PTE bit to
support three kernel features (devmap, soft-dirty,uffd-wp). Users cannot have
them supported at the same time (have to select one when building the kernel).
This patchset has been tested with:
1) The kselftest mm suite in which soft-dirty, madv_populate, test_unmerge_uffd_wp,
and uffd-unit-tests run and pass, and no regressions are observed in any of the
other tests.
2) CRIU:
- 'criu check --feature mem_dirty_track' returns supported
- incremental_dumps works fine
- zdtm test suite can run under host mode
V1 -> V2:
- Add uffd-wp supported;
- Make soft-dirty uffd-wp and devmap mutually exclusive which all use the same PTE bit;
- Add test results of CRIU in the cover-letter.

The PTE bit(9) on RISC-V is reserved for software, it is used by DEVMAP
now which has to be disabled if we want to use bit(9) for other features,
since there's no more free PTE bit on RISC-V now.
So to make ARCH_HAS_PTE_DEVMAP selectable, this patch uses it as
the build condition of devmap definitions.

The PTE bit(9) is reserved for software, now used by DEVMAP,
this patch reuse bit(9) for soft-dirty which is enabled only
if !CONFIG_ARCH_HAS_PTE_DEVMAP, in other words, soft-dirty
and devmap will be mutually exclusive on RISC-V.
To add swap PTE soft-dirty tracking, we borrow bit (4) which is
available for swap PTEs on RISC-V systems.

Reuse PTE bit(9) for uffd-wp tracking and make it mutually exclusive
with soft-dirty and DEVMAP which all use this PTE bit.
Additionally for tracking the uffd-wp state as a pte swp bit,
we use swap entry pte bit(4) which is also used by swp
soft-dirty tracking.
