asm-generic/tlb: Introduce CONFIG_HAVE_MMU_GATHER_NO_GATHER=y
Add the Kconfig option HAVE_MMU_GATHER_NO_GATHER to the generic
mmu_gather code. If the option is set the mmu_gather will not
track individual pages for delayed page free anymore. A platform
that enables the option needs to provide its own implementation
of the __tlb_remove_page_size() function to free pages.
No change in behavior intended.
