d2125043ae generic sys_fork / sys_vfork / sys_clone 
... and get rid of idiotic struct pt_regs * in asm-generic/syscalls.h
prototypes of the same, while we are at it.  Eventually we want those
in linux/syscalls.h, of course, but that'll have to wait a bit.

Note that there are *three* variants of sys_clone() order of arguments.
Braindamage galore...

e0e431aa45 alpha: simplify fork and friends 
* no need to restore everything from switch_stack when we only need $26
* no need to pass current_pt_regs() manually, we can just as easily
calculate it in alpha_clone/alpha_vfork ($8 + constant)
* interpretation of zero usp as "use the parent's" is simpler in copy_thread();
let fork and vfork just pass 0.

22ce19cb43 video: exynos_dp: Reset and initialize DP before requesting irq 
If DP is not reset properly before kernel bootup(in bootloader code),
there can be few pending interrupts, and sometimes they invoke
DP irq handler as soon as the irq handler is registered in DP probe.
So, we make the DP driver more robust by resetting and
initializing DP at the earliest and then registering the irq handler.
