Subject: target/s390x: Replace legacy cpu_physical_memory_[un]map() calls (2/3)
X-Git-Tag: v10.2.0-rc1~68^2~4
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=64321858d0735191b6160ba78f2282a67df6d9d9;p=thirdparty%2Fqemu.git

target/s390x: Replace legacy cpu_physical_memory_[un]map() calls (2/3)

Commit b7ecba0f6f6 ("docs/devel/loads-stores.rst: Document our
various load and store APIs") mentioned cpu_physical_memory_*()
methods are legacy, the replacement being address_space_*().

Replace the *_map() / *_unmap() methods in cpu_[un]map_lowcore().
No behavioral change expected.
