This appears to be due to the fact that KVM_PROFILING is defined
unconditionally in my kernel, but "prof_on" is only defined if
CONFIG_PROFILING is enabled. Commenting out that chunk of code in x86.c
lets everything build.
If CONFIG_PROFILING is off, prof_on is defined to 0. But we may miss
some include on older kernels. Does adding linux/profile.h to x86.c
solve the issue as well?
It would appear that I got the explanation wrong. CONFIG_PROFILING is
enabled on my kernel. The problem is that our OS vendor has included a
patch to convert prof_on to immediate values, which requires a change in
x86.c.
Never mind, nothing to see here.
