Posting pre-PR because I had to adjust Emilio's QTree patch [1],
and added a new patch to avoid an assert that can be generated
with incorrect -R reserved_va values vs the ARM commpage.

Emilio Cota (2):
util: import GTree as QTree
tcg: use QTree instead of GTree
Richard Henderson (9):
linux-user: Diagnose misaligned -R size
include/exec: Change reserved_va semantics to last byte
accel/tcg: Pass last not end to page_set_flags
accel/tcg: Pass last not end to page_reset_target_data
accel/tcg: Pass last not end to PAGE_FOR_EACH_TB
accel/tcg: Pass last not end to page_collection_lock
accel/tcg: Pass last not end to tb_invalidate_phys_page_range__locked
accel/tcg: Pass last not end to tb_invalidate_phys_range
linux-user/arm: Take more care allocating commpage
