patching kernel sources (as of 0.7)

kab_unpack_kernel_source:
- uncompress & untar kernel source code to $BUILD_DIR (“build/”)
kab_apply_vserver_patch:
- prepare vserver patch
  - make a copy of $RAW_PATCHNAME to “$RAW_PATCHNAME-as-downloaded” - if it doesn't exists already
  - otherwise restore $RAW_PATCHNAME from $RAW_PATCHNAME-as-downloaded
  - make a copy of $RAW_PATCHNAME to “generic.diff”
  - if patches are given by –vspatch-patch, expire older ones to $SRC_DIR/00-expired
  - if current kernel source version does not match the kernel version of the latest patch:
    - look for files named [0-9][0-9]-*.diff and apply them to “generic.diff”
      - therefore replace the name of the patch file to be patched by “generic.diff”
  - extract the value of the “NAME” variable from the current kernel source Makefile
  - replace VERSION PATCHLEVEL EXTRAVERSION and NAME inside kernel source Makefile to:
    - at least attach our signature
    - fix version information
  - save the patched vserver patch file to $PATCHNAME
- apply the patch $PATCHNAME to the kernel source tree
- return $KERN_FULL_VERSION to calling process
kab_apply_post_vserver_patch_patches:
- apply patches specified with “–add-patch”
  - this is where linux-*/script/package/builddeb is modified
