Since r303776 I'm unable to build a custom kernel with "nooptions SMP" specified. The kernel conf I'm using consists of: include GENERIC nooptions SMP make.conf is empty. The last excerpt from the compilation is: cc -c -O2 -pipe -fno-strict-aliasing -std=c99 -g -Wall -Wredundant-decls -Wnested-externs -Wstrict -prototypes -Wmissing-prototypes -Wpointer-arith -Winline -Wcast-qual -Wundef -Wno-pointer-sign -f format-extensions -Wmissing-include-dirs -fdiagnostics-show-option -Wno-error-tautological-compare -Wno-error-empty-body -Wno-error-parentheses-equality -Wno-error-unused-function -nostdinc -I. -I/usr/src/sys -I/usr/src/sys/contrib/altq -I/usr/src/sys/contrib/libfdt -D_KERNEL -DHAVE_KERNEL_OPT ION_HEADERS -include opt_global.h -fno-omit-frame-pointer -mno-omit-leaf-frame-pointer -mno-aes -mn o-avx -mcmodel=kernel -mno-red-zone -mno-mmx -mno-sse -msoft-float -fno-asynchronous-unwind-tables -ffreestanding -fstack-protector -gdwarf-2 -Werror /usr/src/sys/x86/xen/hvm.c /usr/src/sys/x86/xen/hvm.c:398:7: error: use of undeclared identifier 'msix_disable_migration' msix_disable_migration == -1) { ^ /usr/src/sys/x86/xen/hvm.c:409:4: error: use of undeclared identifier 'msix_disable_migration' msix_disable_migration = 1; ^ 2 errors generated. *** Error code 1 Stop. The build above is from a system running 10.3-STABLE #0 r303775 amd64, but it appears to affect i386 with a similar configuration as well. The same or very similar error appears to be produced when building against both r303776 and r304519 (the last I've tested against). I believe all relevant local changes have been rolled back, but unfortunately I'm not in a position to test a build on a completely fresh install at present. While I think I have eliminated all likely sources of user meddling, my apologies in advance if this isn't the case.
Assign to committer of r303776.

Sorry for the breakage. Will MFC in a few days.
