So add a workaround local to tlbex.S - the proper fix is to change asm-generic/pgtable-* headers to expose the defines for __ASSEMBLY__ too Signed-off-by: Vineet Gupta --- arch/arc/mm/tlbex.S | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/arch/arc/mm/tlbex.S b/arch/arc/mm/tlbex.S index 6b5872197005..d08bd09a0afc 100644 --- a/arch/arc/mm/tlbex.S +++ b/arch/arc/mm/tlbex.S @@ -145,6 +145,14 @@ ex_saved_reg1: ;TLB Miss handling Code ;============================================================================ +#ifndef PMD_SHIFT +#define PMD_SHIFT PUD_SHIFT +#endif + +#ifndef PUD_SHIFT +#define PUD_SHIFT PGDIR_SHIFT +#endif + ;----------------------------------------------------------------------------- ; This macro does the page-table lookup for the faulting address. ; OUT: r0 = PTE faulted on, r1 = ptr to PTE, r2 = Faulting V-address -- 2.25.1 _______________________________________________ linux-snps-arc mailing list linux-snps-arc@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-snps-arc
