# VxMicro kernel version information
#
# This make fragment sets the version variables which are to be built into
# the kernel.
#
# The kernel version has the form 'w.x.y.z', where each field is a single nibble.
# The nibble 'w' represents the generation release number,
# 'x' represents the major release number,
# 'y' represents the minor release number, and
# 'z' represents the revision release number.
#
# The prefix is required as this macro will be combined with two other
# macros (KERNEL_VERSION_FLAGS and KERNEL_VERSION_RESERVED) to create the
# complete 32-bit kernel version value.
