184003a924 x86: Use fragments instead of a complete config
This reduces the defconfig file to only those options needed
for the platform. We also introduce a kernel independent config
file (no micro/nano prefix) that be the default.
Sanity checks depends on the nano/micro file naming, so until it
is modified to support the new model, we keep the old files.

83acfa3efb add kernel default config fragments
The files will have the needed fragments to move a .config
file to either a nano or micro kernel .config. This will let us
get rid of the micro_*_defconfig/nano_*_defconfig in the future
and once the sanitychecks are adapted leaving us with a single
fragment file per platform and thus making it easier to maintain.

32e1ecb827 kbuild: add generic mergeconfig target, %.config
"scripts/kconfig/merge_config.sh && make oldconfig" works well
enough for merging local config fragments, but Kbuild currently has
the entry points only for "kvmconfig" and "tinyconfig".

This commit provides the generic target for mergeconfig, so we can
manage our own config fragments easily:
put "foo.config" in arch/$(SRCARCH)/configs/ or kernel/configs/,
and then run "make foo.config".

Now "make kvmconfig" is just a shorthand of "make kvm_guest.config".
Likewise, "make tinyconfig" is equivalent to
"make allnoconfig tiny.config".

8f298d3fe1 merge_config.sh: rename MAKE to RUNMAKE
The variable "MAKE" is used to store the command name that has
invoked the Makefile.  (Actually, it is already set to "make"
if you run this script from a Makefile.)

In this script, however, it is used to determine if Make should be
run or not.  It is not what we usually expect.

15e1669e48 kbuild: mergeconfig: move an error check to merge_config.sh
Currently, "make tinyconfig" does not work with "-j" option.

  $ make mrproper
  $ make -j8 tinyconfig
    HOSTCC  scripts/basic/fixdep
    HOSTCC  scripts/kconfig/conf.o
    SHIPPED scripts/kconfig/zconf.tab.c
    SHIPPED scripts/kconfig/zconf.lex.c
    SHIPPED scripts/kconfig/zconf.hash.c
    HOSTCC  scripts/kconfig/zconf.tab.o
    HOSTLD  scripts/kconfig/conf
  scripts/kconfig/conf --allnoconfig Kconfig
  #
  # configuration written to .config
  #
  scripts/kconfig/Makefile:122: *** You need an existing .config
  for this target.  Stop.
  make: *** [tinyconfig] Error 2

As shown above, "allnoconfig" has created the .config file before
mergeconfig is called, but Make still raises a false alarm because
of some sort of race condition.

We can fix this issue by moving the error check to the shell script.

Anyway, scripts/kconfig/merge_config.sh always requires an existing
.config as a base file.  It is reasonable to check its existence in
the shell script.

8253b90cfc microkernel: add task pointer list
Due to similar padding issue as pipe, the list of task object
may not be used directly. As mentioned before, some compiler/linker
may pad the large struct. For example, compiling under gcc and
march=i686 pads the struct to 32-byte alignment (march=atom to
64-byte alignment). This causes issue with sizeof() and pointer
arithmetic because they have no idea about the padding.
When the stars align in a certain way, these task structs may be
corrupted. So add a task pointer list and use it for task
manipulation. The task list remains as it is beneficial to group
them together to take advantage of cache locality.
