Changelog:
v3:
- Split changes to create_safe_exec_page() into several patches for
easier review as request by Mark Rutland. This is why this series
has 3 more patches.
- Renamed trans_table to tans_pgd as agreed with Mark. The header

Usually, gotos are used to handle cleanup after exception, but
in case of create_safe_exec_page there are no clean-ups. So,
simply return the errors directly.

create_safe_exec_page is a local function that uses the
get_safe_page() to allocate page table and pages and one pages
that is getting mapped.
Remove the allocator related arguments, and use get_safe_page
directly, as it is done in other local functions in this
file.

Hi John
I can test any patches given a link to the diff, and am happy to do so.
If I've understood your suggestion correctly, I will try commenting
out all of the entries, then add them back one-by-one until I get a
non-booting situation. I'll let you know how I get on.
The OS I'm testing is Lib
Now, that we abstracted the required functions move them to a new home.
Later, we will generalize these function in order to be useful outside
of hibernation.

Make the last private functions in page table copy path generlized for use
outside of hibernate.
Switch to use the provided allocator, flags, and source page table. Also,
unify all copy function implementations to reduce the possibility of bugs.
All page table levels are implemented symmetrically.
Now, that we have transitional page tables configured, temporarily enable
MMU to allow faster relocation of segments to final destination.
The performance data: for a moderate size kernel + initramfs: 25M the
relocation was taking 0.382s, with enabled MMU it now takes
0.019s only or x20 improvemen
Configure a page table located in kexec-safe memory that has
the following mappings:
1. identity mapping for text of relocation function with executable
permission.
2. identity mapping for argument for relocation function.
3. linear mappings for all source ranges
4. linear mappings for all dest
Thre is PMD_SECT_RDONLY that is used in pud_* function which is confusing.

Currently, kernel relocation function is configured in machine_kexec()
at the time of kexec reboot by using control_code_page.
This operation, however, is more logical to be done during kexec_load,
and thus remove from reboot time. Move, setup of this function to
newly added machine_kexec_post_loa

trans_pgd_create_copy() and trans_pgd_map_page() are going to be
the basis for public interface of new subsystem that handles page
tables for cases which are between kernels: kexec, and hibernate.

create_safe_exec_page() allocates a safe page and maps it at a
specific location, also this function returns the physical address
of newly allocated page.
The destination VA, and PA are specified in arguments: dst_addr,
phys_dst_addr
However, within the function it uses "dst" which has unsigned l
