I've pushed a newer version, with the following changes since the
previous post :

 * Provide a "same as kernel headers" choice for the version selection

 * Use "depends on" instead of an "if...endif" block when a single
   option needs to be conditionnaly shown

 * Merge BR2_LINUX_KERNEL_PATCH and BR2_LINUX_KERNEL_PATCH_LOCATION
   into a single option. When the option value is empty, not patch is
   applied. When the option value is non empty, it is considered as a
   path or URL to a patch to be applied to the kernel.

 * Rename BR2_LINUX_KERNEL_USE_CUSTOM to
   BR2_LINUX_KERNEL_USE_CUSTOM_FILE.

 * Fix the default value for the kernel binary format: BR2_i386
   instead of BR2_386 and bzImage by default on BR2_x86_64.

 * Use BR2_KERNEL_MIRROR where appropriate

 * Use the $(shell...) construct instead of back-quotes

 * Use $(filter ...) instead of multiple $(findstring ...)

 * Fix escaping of linux-*.patch -> linux-\*.patch

 * Remove yes "" | make oldconfig constructs

 * Install the modules only if CONFIG_MODULES is enabled

 * Add newline at the end of linux.mk.

 * Add $(TARGET_MAKE_ENV) to $(MAKE) invocations so that a PATH
   containing $(HOST_DIR)/usr/bin is used when building the
   kernel. This is needed in order to allow the kernel to find mkimage
   and other host tools (module-init-tools). This fixes the problem
   reported by Ossy.

 * Rename option mentioning "stable" so as to not use the "stable"
   wording since it could be confusing for users.
