Hi Peter,

Probably we don't have a maintainer for PPC TCG backend.

Subject: [PATCH 1/8] tcg: Clean up direct block chaining data fields
Date: Thu, 24 Mar 2016 13:39:14 +0300

From: Sergey Fedorov <address@hidden>

Briefly describe in a comment how direct block chaining is done. It
should help in understanding of the following data fields.

Rename some fields in TranslationBlock and TCGContext structures to
better reflect their purpose (dropping excessive 'tb_' prefix in
TranslationBlock but keeping it in TCGContext):
   tb_next_offset  =>  jmp_reset_offset
   tb_jmp_offset   =>  jmp_insn_offset
   tb_next         =>  jmp_target_addr
   jmp_next        =>  jmp_list_next
   jmp_first       =>  jmp_list_first

Avoid using a magic constant as an invalid offset which is used to
indicate that there's no n-th jump generated.
