Subject: [Qemu-devel] [PATCH v3 11/35] cputlb: move CPU_LOOP() for tlb_reset() to exec.c
Date: Sat, 18 Jul 2015 02:40:21 -0700	[thread overview]
Message-ID: <dd11bdaeaee27b8b55f2973ebc34cfacb6f46efe.1437212383.git.crosthwaite.peter@gmail.com> (raw)
In-Reply-To: <cover.1437212383.git.crosthwaite.peter@gmail.com>
In-Reply-To: <cover.1437212383.git.crosthwaite.peter@gmail.com>

To prepare for multi-arch, cputlb should only have awareness of one
single architecture. This means it should not have access to the full
CPU lists which may be heterogeneous. Instead, push the CPU_LOOP() up
to the one and only caller in exec.c.

Signed-off-by: Peter Crosthwaite <crosthwaite.peter@gmail.com>

Easier reading with git diff -w

Changed since RFCv2:
split off to new patch (previously part of core virtualisation patch)
