I've updated mm-unstable to this version, thanks. I skipped the added-to-mm
emails to avoid wearing out people's inboxes.

Now all the platforms enable ARCH_HAS_GET_PAGE_PROT. They define and export
own vm_get_page_prot() whether custom or standard DECLARE_VM_GET_PAGE_PROT.
Hence there is no need for default generic fallback for vm_get_page_prot().
Just drop this fallback and also ARCH_HAS_GET_PAGE_PROT mechanism.

Now that protection_map[] has been moved inside those platforms that enable
ARCH_HAS_VM_GET_PAGE_PROT. Hence generic protection_map[] array now can be
protected with CONFIG_ARCH_HAS_VM_GET_PAGE_PROT intead of __P000.

This moves protection_map[] inside the platform and makes it a static. This
also defines a helper function add_encrypt_protection_map() that can update
the protection_map[] array with pgprot_encrypted().

This just converts the generic vm_get_page_prot() implementation into a new
macro i.e DECLARE_VM_GET_PAGE_PROT which later can be used across platforms
when enabling them with ARCH_HAS_VM_GET_PAGE_PROT. This does not create any
functional change.

Build protect generic protection_map[] array with __P000, so that it can be
moved inside all the platforms one after the other. Otherwise there will be
build failures during this process. CONFIG_ARCH_HAS_VM_GET_PAGE_PROT cannot
be used for this purpose as only certain platforms enable this config n
__SXXX/__PXXX macros is an unnecessary abstraction layer in creating the
generic protection_map[] array which is used for vm_get_page_prot(). This
abstraction layer can be avoided, if the platforms just define the array
protection_map[] for all possible vm_flags access permission combinations
