Revision c2471e79a7ea0f48e3ae9253e1f3688a44cc944d authored by Mike Rapoport on 12 July 2019, 03:58:39 UTC, committed by Linus Torvalds on 12 July 2019, 18:05:46 UTC
Replace __get_free_page() and alloc_pages() calls with the generic __pte_alloc_one_kernel() and __pte_alloc_one(). There is no functional change for the kernel PTE allocation. The difference for the user PTEs, is that the clear_pte_table() is now called after pgtable_page_ctor() and the addition of __GFP_ACCOUNT to the GFP flags. The pte_free() and pte_free_kernel() versions are identical to the generic ones and can be simply dropped.
