Subject: [PATCH v2 6/6] exec/cpu_ldst: Move tlb* declarations to "exec/exec-all.h"
Date: Mon,  8 Feb 2021 00:23:10 +0100	[thread overview]
Message-ID: <20210207232310.2505283-7-f4bug@amsat.org> (raw)
In-Reply-To: <20210207232310.2505283-1-f4bug@amsat.org>

Keep MMU functions in "exec/cpu_ldst.h", and move TLB functions
to "exec/exec-all.h". As tlb_addr_write() is only called in
accel/tcg/cputlb.c, make move it there as a static function.

Doing so we removed the "tcg/tcg.h" dependency on "exec/cpu_ldst.h".
