v0.39

• Feature: two new methods for reading MSR without a recent-enough dd binary: using perl or the msr-tools when these are present
• Feature: add detection of RSBA feature bit (set by some hypervisors) indicating possible RSB underflow host CPU vulnerability, and require kernel support for RSB stuffing even on non-Skylake CPUs when this is the case
• Feature: support for /boot partition on a btrfs subvolume (#226)
• Feature: add standard location of Arch armv5/armv7 kernel image (#227)
• Fix: the ARCH_CAPABILITIES MSR wasn't read correctly, preventing proper SSB_NO and RDCL_NO feature bits detection
