[Qemu-devel] [PATCH 3/6] w64: Fix data type of parameters for flush_icache_range

[Stefan Weil <sw@weilnetz.de>]

flush_icache_range takes two address parameters which must be large
enough to address any address of the host.

For hosts with sizeof(unsigned long) == sizeof(void *), this patch
changes nothing. All currently supported hosts fall into this category.

For w64 hosts, sizeof(unsigned long) is 4 while sizeof(void *) is 8,
so the use of tcg_target_ulong is needed for i386 and tci (the tcg
targets which work with w64).
