Generate offsets of selected structure members to be used in assembly files. The asm-offsets.c file is compiled into assembly (.s) file and parsed by asm-offsets.sh script to generate the final include header asm-offsets.h. This is needed to be able to access per-cpu variables in assembly. Signed-off-by: Pawel Wieczorkiewicz <[email protected]>
Now that we have the asm-offsets.h generated for the per-cpu variable, we can use it directly instead of passing argument from the C code. Signed-off-by: Pawel Wieczorkiewicz <[email protected]>

I reviewed these commits in #284, see my comments there, starting at #284 (review) |
Splitting cpu_regs_t into cpu_exc_t and cpu_regs_t using cpu_exc_t allows to create asm-offset entries for the struct members to be used directly in entry.S (allows to use different structure offsets when in exception handler and when in syscall).
