yu-cheng yu a5fe93a549 x86/fpu: Disable MPX when eagerfpu is off ... This issue is a fallout from the command-line parsing move. When "eagerfpu=off" is given as a command-line input, the kernel should disable MPX support. The decision for turning off MPX was made in fpu__init_system_ctx_switch(), which is after the selection of the XSAVE format. This patch fixes it by getting that decision done earlier in fpu__init_system_xstate().
