[Qemu-devel] [PATCH v6 0/6] tcg: Misc clean-up patches

[Sergey Fedorov]

From: Sergey Fedorov <address@hidden>

This patch series consists of various general TCG clean-up patches extracted
from Paolo's MTTCG tree [1] and Alex's MTTCG base enablement tree [2]. I also
add here a patch from myself to rework tb_invalidated_flag based on the Paolo's
"tcg: move tb_invalidated_flag to CPUState" patch from the original verions of
this series. Another patch of mine cleans up from a misleading 'next_tb'
variable.

The main idea is to review and merge these patches separately from the MTTCG
series to cut the latter and make it easier to review.

This series is based on commit 6d6e9af2ed1c ("tcg: Allow goto_tb to any
target PC in user mode") [3] and is available at [4].
