Subject: x86: move INVPCID_TYPE_* to x86-defns.h
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=6e2ea60524b51b1eacff38d15c49efc5e7f2c3b4;p=people%2Fiwj%2Fxen.git

x86: move INVPCID_TYPE_* to x86-defns.h

This way the insn emulator can then too use the #define-s. In place of
the TYPE infix add an X86 prefix.
