2012-12-19new helper: compat_user_stack_pointer()Al Viro3-2/+13
Compat counterpart of current_user_stack_pointer(); for most of the biarch architectures those two are identical, but e.g. arm64 and arm use different registers for stack pointer... Note that amd64 variants of current_user_stack_pointer/compat_user_stack_pointer do *not* rely on pt_regs having been through FIXUP_TOP_OF_STACK. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2012-12-19new helper: current_user_stack_pointer()Al Viro7-0/+14
Cross-architecture equivalent of rdusp(); default is user_stack_pointer(current_pt_regs()) - that works for almost all platforms that have usp saved in pt_regs. The only exception from that is ia64 - we want memory stack, not the backing store for register one. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2012-12-19missing user_stack_pointer() instancesAl Viro9-0/+10

2012-12-19Bury the conditionals from kernel_thread/kernel_execve seriesAl Viro63-131/+6
All architectures have CONFIG_GENERIC_KERNEL_THREAD CONFIG_GENERIC_KERNEL_EXECVE __ARCH_WANT_SYS_EXECVE None of them have __ARCH_WANT_KERNEL_EXECVE and there are only two callers of kernel_execve() (which is a trivial wrapper for do_execve() now) left. Kill the conditionals and make both callers use do_execve(). Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2012-11-29get rid of ptrace_signal_deliver() argumentsAl Viro4-5/+5
the first one is equal to signal_pt_regs(), the second is never used (and always NULL, while we are at it). Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2012-11-29new helper: signal_pt_regs()Al Viro3-0/+11
Always equal to task_pt_regs(current); defined only when we are in signal delivery. It may be different from current_pt_regs() - e.g. architectures like m68k may have pt_regs location on exception different from that on a syscall and signals (just as ptrace handling) may happen on exceptions as well as on syscalls. When they are equal, it's often better to have signal_pt_regs defined (in asm/ptrace.h) as current_pt_regs - that tends to be optimized better than default would be. However, optimisation is the only reason why we might want an arch-specific definition; if current_pt_regs() and task_pt_regs(current) have different values, the latter one is right.
