[PATCH 0/2] accel/tcg: fix page invalidation in tb_invalidate_phys_range()

[Mark Cave-Ayland]

This series contains 2 patches: the first is a fix for page invalidation in
tb_invalidate_phys_range() which resolves the crash reported by Howard and
Cédric when booting MacOS 9 under qemu-system-ppc -M mac99,via=pmu.

The second patch adds an assert() to tb_invalidate_phys_page_range__locked()
which is enabled by --enable-debug-tcg to ensure that both the start and last
addresses are within the same target page.

I've confirmed that this assert() is first triggered by the commit that
initially introduced the bug e506ad6a05 ("accel/tcg: Pass last not end to
tb_invalidate_phys_range") when building QEMU with --enable-debug and
doesn't trigger after the series is applied.
