This patch fixes a stack corruption caused by the routine since it pushes the registers R4, R5, R6, and R7 onto the stack that results in a restorer crash while restoring a zombie (https://bugzilla.openvz.org/show_bug.cgi?id=2663) Reported-by:

To restore SAS we have two ways: - call for sigaltstack explicitly in restorer.c right before we call for sigreturn - pass stack value to sigreturn call and allow the kernel to restore stack for us Since second way is a simplier one -- we stick with it.

Alexander Kartashov authored
This patch modifies the ARM syscall glue as follows: * the macros syscallX that produce different code for syscalls with different number of arguments are replaced by the generic syscall thunk copied from libc; * the syscall tables generation script is simplified since the syscall argument number analysis is redundant; * the ARMv7 specific instruction MOVW is eliminated.

Will need it to retrieve signal stack parameters. Note for simplicty I declared the syscall having void * arguments, while libc has it as stack_t *. This need to be cleaned up one day (because we use similar structure for sigframe definition and need to merge both definitions down). ARM syscall def from alekskartashov@ Signed-off-by:

Make criu still set scheduler and priority on restored process even when its setting is the default one. Or if criu itself has special setting on it, forked processes will inherit it, which is a wrong setting for restored ones. Signed-off-by:
