[PATCH] kvmtool: ARM: madvise mergeable and hugepage separately

The madvise behavior is not a bit field and hence can not be or'ed. Also madvise_behavior_valid checks the flag using a case statement hence only one behavior is supposed to be supplied. Call madvise twice, once for MERGEABLE and once for HUGEPAGE. Signed-off-by: Stefan Agner --- arm/kvm.

KVM on ARM crashes with new VGIC v4.7-rc7

Hi, I tried KVM on a Cortex-A7 platform (i.MX 7Dual SoC) and encountered this stack trace immediately after invoking qemu-system-arm: Unable to handle kernel paging request at virtual address ffe4 pgd = 8ca52740 [ffe4] *pgd=8080007003, *pmd=8ff7e003, *pte= Internal error: Oops
