Subject: [PATCH] powerpc/nohash: Remove pte_same()
Date: Mon, 31 Jan 2022 08:16:48 +0000 [thread overview]
Message-ID: <83c97bd58a3596ef1b0ff28b1e41fd492d005520.1643616989.git.christophe.leroy@csgroup.eu> (raw)
arch/powerpc/include/asm/nohash/{32/64}/pgtable.h has
#define __HAVE_ARCH_PTE_SAME
#define pte_same(A,B) ((pte_val(A) ^ pte_val(B)) == 0)
include/linux/pgtable.h has
#ifndef __HAVE_ARCH_PTE_SAME
static inline int pte_same(pte_t pte_a, pte_t pte_b)
{
return pte_val(pte_a) == pte_val(pte_b);
}
#endif
Remove the powerpc version which is similar to the generic one.
