Konstantin Belousov edc8222303 Make kstack_pages a tunable on arm, x86, and powepc. On i386, the ... initial thread stack is not adjusted by the tunable, the stack is allocated too early to get access to the kernel environment. See TD0_KSTACK_PAGES for the thread0 stack sizing on i386. The tunable was tested on x86 only. From the visual inspection, it seems that it might work on arm and powerpc. The arm USPACE_SVC_STACK_TOP and powerpc USPACE macros seems to be already incorrect for the threads with non-default kstack size. I only changed the macros to use variable instead of constant, since I cannot test. On arm64, mips and sparc64, some static data structures are sized by KSTACK_PAGES, so the tunable is disabled.
