arm64/mm: don't initialize pgd_cache twice
When PGD_SIZE != PAGE_SIZE, arm64 uses kmem_cache for allocation of PGD memory. That cache was initialized twice: first through pgtable_cache_init() alias and then as an override for weak pgd_cache_init(). Remove the alias from pgtable_cache_init() and keep the only pgd_cache initialization in pgd_cache_init(). Fixes: caa841360134 ("x86/mm: Initialize PGD cache during mm initialization") Signed-off-by: Mike Rapoport <rppt@linux.ibm.com> Signed-off-by: Will Deacon <will.deacon@arm.com>
