Thanks for doing this. I just posted my fix to the patch system, before seeing yours (it also requires change in boot/compressed/Makefile - hyp-stub is built twice). See the previous discussion about this issue here: http://thread.gmane.org/gmane.linux.ports.arm.kernel/479256 Thanks, Jean-Philippe > > Best regards, > > V. > > > arch/arm/kernel/Makefile | 2 ++ > 1 file changed, 2 insertions(+) > > diff --git a/arch/arm/kernel/Makefile b/arch/arm/kernel/Makefile > index 2c5f160..15684c5 100644 > --- a/arch/arm/kernel/Makefile > +++ b/arch/arm/kernel/Makefile > @@ -88,6 +88,8 @@ obj-$(CONFIG_DEBUG_LL) += debug.o > obj-$(CONFIG_EARLY_PRINTK) += early_printk.o > > obj-$(CONFIG_ARM_VIRT_EXT) += hyp-stub.o > +AFLAGS_hyp-stub.o :=-Wa,-march=armv7-a > + > ifeq ($(CONFIG_ARM_PSCI),y) > obj-$(CONFIG_SMP) += psci_smp.o > endif > -- > 2.7.0 > > > _______________________________________________ > linux-arm-kernel mailing list > [email protected] > http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
