At present, the "average" guestimate of TB size is way too small, leading to many unused entries in the pre-allocated TB array. For a guest with 1GB ram, we're currently allocating 256MB for the array. Survey arm, alpha, aarch64, ppc, sparc, i686, x86_64 guests running on x86_64 and ppc64 hosts and select a new average. The size of the array drops to 81MB with no more flushing than before. Reviewed-by: Aurelien Jarno <aurelien@aurel32.net> Signed-off-by: Richard Henderson <rth@twiddle.net>
