Introduce utility functions setting the foundation for ptdescs. These
will also assist in the splitting out of ptdesc from struct page.
Functions that focus on the descriptor are prefixed with ptdesc_* while
functions that focus on the pagetable are prefixed with pagetable_*.

The MM subsystem is trying to shrink struct page. This patchset
introduces a memory descriptor for page table tracking - struct ptdesc.
This patchset introduces ptdesc, splits ptdesc from struct page, and
converts many callers of page table constructor/destructors to use ptdescs.

identifier declared in an outer scope"
The function parameters renamed in this patch are hiding a variable defined
in an enclosing scope.
The following rename is made:
- s/cfg/file/
to distinguish
RISC-V doesn't support interrupts for the time being, so it would be nice to
have polling mode.
The patch adds new option to console='...,polling' which forces driver to use
polling mode.
If there is no interrupt property in UART node, then polling will be used.
According to 4.2.2 National

Add SET_CPUFREQ_HWP xen_sysctl_pm_op to set HWP parameters. The sysctl
supports setting multiple values simultaneously as indicated by the
set_params bits. This allows atomically applying new HWP configuration
via a single wrmsr.

Rearrange code now that xen_sysctl_pm_op's get_para fields has the
nested union and struct. In particular, the scaling governor
information like scaling_available_governors is inside the union, so it
is not always available. Move those fields (op->u.get_para.u.s.u.*)
