      stackprotector: update make rules · 5d707e9c
      Tejun Heo 提交于
      Impact: no default -fno-stack-protector if stackp is enabled, cleanup
      
      Stackprotector make rules had the following problems.
      
      * cc support test and warning are scattered across makefile and
        kernel/panic.c.
      
      * -fno-stack-protector was always added regardless of configuration.
      
      Update such that cc support test and warning are contained in makefile
      and -fno-stack-protector is added iff stackp is turned off.  While at
      it, prepare for 32bit support.

      Tejun Heo 提交于
      Impact: misc udpate
      
      * wrap content with CONFIG_CC_STACK_PROTECTOR so that other arch files
        can include it directly
      
      * add missing includes
      
      This will help future changes.

      elf: add ELF_CORE_COPY_KERNEL_REGS() · 6cd61c0b
      Tejun Heo 提交于
      ELF core dump is used for both user land core dump and kernel crash
      dump.  Depending on architecture, register might need to be accessed
      differently for userland and kernel.  Allow architectures to define
      ELF_CORE_COPY_KERNEL_REGS() and use different operation for kernel
      register dump.

      x86: fix math_emu register frame access · d315760f
      Tejun Heo 提交于
      do_device_not_available() is the handler for #NM and it declares that
      it takes a unsigned long and calls math_emu(), which takes a long
      argument and surprisingly expects the stack frame starting at the zero
      argument would match struct math_emu_info, which isn't true regardless
      of configuration in the current code.
      
      This patch makes do_device_not_available() take struct pt_regs like
      other exception handlers and initialize struct math_emu_info with
      pointer to it and pass pointer to the math_emu_info to math_emulate()
      like normal C functions do.  This way, unless gcc makes a copy of
      struct pt_regs in do_device_not_available(), the register frame is
      correctly accessed regardless of kernel configuration or compiler
      used.
      
      This doesn't fix all math_emu problems but it at least gets it
      somewhat working.

      module: remove over-zealous check in __module_get() · 7f9a50a5
      Rusty Russell 提交于
      Impact: fix spurious BUG_ON() triggered under load
      
      module_refcount() isn't reliable outside stop_machine(), as demonstrated
      by Karsten Keil <kkeil@suse.de>, networking can trigger it under load
      (an inc on one cpu and dec on another while module_refcount() is tallying
       can give false results, for example).
      
      Almost noone should be using __module_get, but that's another issue.
