x86/mpx: Use compatible types in comparison to fix sparse error
info->si_addr is of type void __user *, so it should be compared against something from the same address space. This fixes the following sparse error: arch/x86/mm/mpx.c:296:27: error: incompatible types in comparison expression (different address spaces) Signed-off-by: Tobias Klauser <tklauser@distanz.ch> Cc: Dave Hansen <dave.hansen@linux.intel.com> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: linux-kernel@vger.kernel.org Signed-off-by: Ingo Molnar <mingo@kernel.org>
