From 7900757ce1b4affda1591aa3fd073e27d202f406 Mon Sep 17 00:00:00 2001 From: "Aneesh Kumar K.V" Date: Tue, 5 May 2020 12:47:11 +0530 Subject: powerpc/hash64: Restrict page table lookup using init_mm with __flush_hash_table_range This is only used with init_mm currently. Walking init_mm is much simpler because we don't need to handle concurrent page table like other mm_context Signed-off-by: Aneesh Kumar K.V Signed-off-by: Michael Ellerman Link: https://lore.kernel.org/r/20200505071729.54912-5-aneesh.kumar@linux.ibm.com --- arch/powerpc/kernel/pci_64.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'arch/powerpc/kernel/pci_64.c') diff --git a/arch/powerpc/kernel/pci_64.c b/arch/powerpc/kernel/pci_64.c index f83d1f69b1dd..30d07fc79dd1 100644 --- a/arch/powerpc/kernel/pci_64.c +++ b/arch/powerpc/kernel/pci_64.c @@ -100,7 +100,7 @@ int pcibios_unmap_io_space(struct pci_bus *bus) pci_name(bus->self)); #ifdef CONFIG_PPC_BOOK3S_64 - __flush_hash_table_range(&init_mm, res->start + _IO_BASE, + __flush_hash_table_range(res->start + _IO_BASE, res->end + _IO_BASE + 1); #endif return 0; -- cgit
