From: Mike Rapoport <rppt@xxxxxxxxxxxxx>
Subject: riscv: switch to generic version of pte allocation
The only difference between the generic and RISC-V implementation of PTE
allocation is the usage of __GFP_RETRY_MAYFAIL for both kernel and user
PTEs and the absence of __GFP_ACCOUNT for the user PTEs.
The conversion to the generic version removes the __GFP_RETRY_MAYFAIL and
ensures that GFP_ACCOUNT is used for the user PTE allocations.
The pte_free() and pte_free_kernel() versions are identical to the generic
ones and can be simply dropped.
