(These two patches are somewhat related but do not depend on each other and
can be applied separately.)
Support -S to use another kernel version (66 bytes)
Normally modprobe will use version information from the currently running
kernel (similar to `uname -r`). This patch adds a compile-time configuration
option to enable the -S switch, which allows specifying a different kernel
version. This can be useful when used with the -D option to determine module
dependencies when building a new initramfs after a kernel upgrade.
