# effectively a sortable identifier for the kernel It encodes the base
# release which is used for overall sorting, plus where patches are
# applied it adds an increasing pNNN patch combination identifier
# (actually the kernel_idx for the entry).  This allows sorting
# as normal by the base kernel version and then sub-sorting by the
# "first time we saw" a patch combination which should keep them in
# approximatly date order.  This patch identifier is not suitable
# for display, so we have to map it to a suitable html fragment for
# display.  This contains the kernel base version plus the truncated
# names of all the patches,
#
# 	2.6.24-mm1 p112
# 	+add-new-string-functions-
# 	+x86-amd-thermal-interrupt
# 
# This mapping is produced when the first mapping is request, with
# a single query over the patches table; the result is then cached.
#
# Note: that we only count a base version as patched if it contains
# patches which are not already "expressed" in the base version.
# This includes both -gitN and -mmN kernels.
