kernel.h: drop inclusion in bitmap.h The bitmap.h header is used in a lot of code around the kernel. Besides that it includes kernel.h which sometimes makes a loop. The problem here is many unneeded loops that make header hell dependencies. For example, how may you move bitmap_zalloc() from C-file to the header? Currently it's impossible. And bitmap.h here is only the tip of an iceberg. kerne.h is a dump of everything that even has nothing in common at all. We may still have it, but in my new code I prefer to include only the headers that I want to use, without the bulk of unneeded kernel code. Break the loop by introducing align.h, including it in kernel.h and bitmap.h followed by replacing kernel.h with limits.h.

vdso: Introduce vdso/align.h The vDSO implementation can only include headers from the vdso/ namespace. To enable the usage of the ALIGN() macro from the vDSO, move linux/align.h to vdso/align.h wholly. As the only dependency linux/const.h is only a wrapper around vdso/const.h anyways adapt that dependency. Also provide a compatibility wrapper linux/align.h.
