Revert "cma: use MEMBLOCK_ALLOC_ANYWHERE for placing CMA regions"
This reverts commit 6308fd5399ae93e35ac381825a279996264a5f78.
As an optimization for kmap/kunmap, the page table entries may
not be completely removed on kunmap. This causes a problem
when memory is XPU protected and the CPU speculates into the
virtual address map. There are functions to remove zero
count entries for kmap calls but kmap_atomic is handled separately.
Remove CMA from highmem until an effective strategy for removing
these entries is found.
