Subject: platform/x86/amd/hsmp: Move structure and macros to header file
X-Git-Tag: v6.13-rc1~147^2~49
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1757d2b8dcf6810d7356d8420606df5080e36260;p=thirdparty%2Fkernel%2Flinux.git

platform/x86/amd/hsmp: Move structure and macros to header file

This is in preparation to splitting ACPI and platform device drivers.
No logical change, move common structures, macros to hsmp.h,
add missed header files, remove unwanted header inclusions,
and re-order the header file in hsmp.c file.
