[PATCH v4 0/2] init cleanups

[Namhyung Kim <namhyung@gmail.com>]

Hello,

This patchset tries to cleanup init/initramfs code especially for syscall
invocation which produces many warnings from sparse because of address
space change. This can be done by wrapping each syscall invocation and
doing such conversions in it using kernel_sys_call() macro suggested by
Arnd Bergmann.

This patchset depends on my previous patch "init: mark __user address space
on string literals" [1] now contained in -mm tree. Actually now it can be
replaced by these patches. Andrew, I can respin this if you want to remove
my previous one in -mm tree.

Any comments would be welcomed.

Thanks.
