for_each_set_bit() is currently horribly inefficient for how we commonly use it. See patch 4 for details. Andrew Cooper (6): x86/vmx: Rewrite vmx_sync_pir_to_irr() to be more efficient xen/bitops: Rename for_each_set_bit() to bitmap_for_each() xen/macros: Introduce BUILD_ERROR() xen/bitops: Introduce for_each_set_bit() ARM/vgic: Use for_each_set_bit() in vgic_set_irqs_pending() x86/xstate: Switch back to for_each_set_bit() xen/arch/arm/gic-vgic.c | 2 +- xen/arch/arm/vgic.c | 8 ++--- xen/arch/arm/vgic/vgic-mmio-v2.c | 2 +- xen/arch/arm/vgic/vgic-mmio.c | 12 +++---- xen/arch/x86/cpu-policy.c | 10 +++--- xen/arch/x86/hvm/vmx/vmx.c | 61 +++++++++++++++++++++++++++----- xen/arch/x86/xstate.c | 8 ++--- xen/common/bitops.c | 29 +++++++++++++++ xen/include/xen/bitmap.h | 12 +++++++ xen/include/xen/bitops.h | 35 ++++++++++++------ xen/include/xen/macros.h | 2 ++ xen/include/xen/self-tests.h | 4 +-- 12 files changed, 142 insertions(+), 43 deletions(-) -- 2.39.2
