Use the newly added vmalloc_no_huge in KVM on s390 to get around a hardware limitation. v2->v3: * do not export __vmalloc_node_range * add vmalloc_no_huge as a wrapper around __vmalloc_node_range * use vmalloc_no_huge instead of __vmalloc_node_range in kvm on s390x Cc: Andrew Morton <akpm@...ux-foundation.org> Cc: Nicholas Piggin <npiggin@...il.com> Cc: Uladzislau Rezki (Sony) <urezki@...il.com> Cc: Catalin Marinas <catalin.marinas@....com> Cc: Thomas Gleixner <tglx@...utronix.de> Cc: Ingo Molnar <mingo@...hat.com> Cc: David Rientjes <rientjes@...gle.com> Cc: Christoph Hellwig <hch@...radead.org> Claudio Imbrenda (2): mm/vmalloc: add vmalloc_no_huge KVM: s390: fix for hugepage vmalloc arch/s390/kvm/pv.c | 2 +- include/linux/vmalloc.h | 1 + mm/vmalloc.c | 16 ++++++++++++++++ 3 files changed, 18 insertions(+), 1 deletion(-) -- 2.31.1
