x86/kvm: Allow runtime control of L1D flush
commit 895ae47f9918833c3a880fbccd41e0692b37e7d9 upstream
All mitigation modes can be switched at run time with a static key now:
- Use sysfs_streq() instead of strcmp() to handle the trailing new line
from sysfs writes correctly.
- Make the static key management handle multiple invocations properly.
- Set the module parameter file to RW
