Pull vdso updates from Thomas Gleixner:

- Make the handling of compat functions consistent and more robust

- Rework the underlying data store so that it is dynamically allocated,
which allows the conversion of the last holdout SPARC64 to the
generic VDSO implementation

- Rework the SPARC64 VDSO to utilize the generic implementation

- Mop up the left overs of the non-generic VDSO support in the core
code

- Expand the VDSO selftest and make them more robust

- Allow time namespaces to be enabled independently of the generic VDSO
support, which was not possible before due to SPARC64 not using it

- Various cleanups and improvements in the related code

mm: convert __HAVE_ARCH_TLB_REMOVE_TABLE to CONFIG_HAVE_ARCH_TLB_REMOVE_TABLE config

For architectures that define __HAVE_ARCH_TLB_REMOVE_TABLE, the page
tables at the pmd/pud level are generally not of struct ptdesc type, and
do not have pt_rcu_head member, thus these architectures cannot support
PT_RECLAIM.

In preparation for enabling PT_RECLAIM on more architectures, convert
__HAVE_ARCH_TLB_REMOVE_TABLE to CONFIG_HAVE_ARCH_TLB_REMOVE_TABLE config,
so that we can make conditional judgments in Kconfig.

mm: introduce CONFIG_ARCH_HAS_LAZY_MMU_MODE

Architectures currently opt in for implementing lazy_mmu helpers by
defining __HAVE_ARCH_ENTER_LAZY_MMU_MODE.

In preparation for introducing a generic lazy_mmu layer that will require
storage in task_struct, let's switch to a cleaner approach: instead of
defining a macro, select a CONFIG option.

This patch introduces CONFIG_ARCH_HAS_LAZY_MMU_MODE and has each arch
select it when it implements lazy_mmu helpers.
__HAVE_ARCH_ENTER_LAZY_MMU_MODE is removed and <linux/pgtable.h> relies on
the new CONFIG instead.

On x86, lazy_mmu helpers are only implemented if PARAVIRT_XXL is selected.
This creates some complications in arch/x86/boot/, because a few files
manually undefine PARAVIRT* options. As a result <asm/paravirt.h> does
not define the lazy_mmu helpers, but this breaks the build as
<linux/pgtable.h> only defines them if !CONFIG_ARCH_HAS_LAZY_MMU_MODE.
There does not seem to be a clean way out of this - let's just undefine
that new CONFIG too.
