Subject: x86: Fix a typo in shadow_get_and_create_l1e().
X-Git-Tag: archive/raspbian/4.8.0-1+rpi1~1^2~14215^2~137
X-Git-Url: https://dgit.raspbian.org/%22http://www.example.com/cgi/%22/%22http:/www.example.com/cgi/%22?a=commitdiff_plain;h=10ab43fd56e729da8f264e3c3da4b4510bfa0460;p=xen.git

x86: Fix a typo in shadow_get_and_create_l1e().

The typo is benign because sh_page_fault() gates the call to
shadow_get_and_create_l1e() on an equivalent test.
