Subject: accel/tcg: Pass CPUTLBEntryFull to tlb_reset_dirty_range_locked
X-Git-Tag: v10.1.0-rc0~117^2~84
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=970354edc09a0ede505cea117b92e71330f1ed53;p=thirdparty%2Fqemu.git

accel/tcg: Pass CPUTLBEntryFull to tlb_reset_dirty_range_locked

While we're renaming things, don't modify addr; save it for
reuse in the qatomic_set.  Compute the host address into a
new local variable.
