Subject: accel/tcg: Use CPUTLBEntryFull.phys_addr in io_failed
X-Git-Tag: v8.2.0-rc0~124^2~13
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0e1144400fc390c0b6c37c252e95961cfab1dde9;p=thirdparty%2Fqemu.git

accel/tcg: Use CPUTLBEntryFull.phys_addr in io_failed

Since the introduction of CPUTLBEntryFull, we can recover
the full cpu address space physical address without having
to examine the MemoryRegionSection.
