2012-11-28generic sys_fork / sys_vfork / sys_cloneAl Viro
... 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...

2012-11-28alpha: simplify fork and friendsAl Viro
* 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.

incidentally, declaring a local variable as __user (!) to make sparse STFU is really sick. Especially since sparse had been 100% right - it *is* a bug. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2012-11-28KVM: VMX: fix invalid cpu passed to smp_call_function_singleXiao Guangrong
In loaded_vmcs_clear, loaded_vmcs->cpu is the fist parameter passed to smp_call_function_single, if the target cpu is downing (doing cpu hot remove), loaded_vmcs->cpu can become -1 then -1 is passed to smp_call_function_single It can be triggered when vcpu is being destroyed, loaded_vmcs_clear is called in the preemptionable context Signed-off-by: Xiao Guangrong <xiaoguangrong@linux.vnet.ibm.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
2012-11-28KVM: use is_idle_task() instead of idle_cpu() to decide when to halt in async_pfGleb Natapov
As Frederic pointed idle_cpu() may return false even if async fault happened in the idle task if wake up is pending. In this case the code will try to put idle task to sleep. Fix this by using is_idle_task() to check for idle task.
