Impact: improve out-of-range fixmap index debugging Commit "1b42f516" defined the __this_fixmap_does_not_exist() function with a WARN_ON(1) in it. This causes the linker to not report an error when __this_fixmap_does_not_exist() is called with a non-constant parameter. Ingo defined __this_fixmap_does_not_exist() because he wanted to get virt addresses of fix memory of nest level by non-constant index. But we can fix this and still keep the link-time check: We can get the four slot virt addresses on link time and store them to array slot_virt[]. Then we can then refer the slot_virt with non-constant index, in the ioremap-leak detection code. Signed-off-by:

Rather than relying on the ever-unreliable system_state, add a specific __vmalloc_start_set flag to indicate whether the vmalloc area has meaningful boundaries yet, and use that in x86-32's __phys_addr and __virt_addr_valid. Signed-off-by:

Impact: fix math-emu related crash while using GDB/ptrace init_fpu() calls finit to initialize a task's xstate, while finit always works on the current task. If we use PTRACE_GETFPREGS on another process and both processes did not already use floating point, we get a null pointer exception in finit. This patch creates a new function finit_task that takes a task_struct parameter. finit becomes a wrapper that simply calls finit_task with current. On the plus side this avoids many calls to get_current which would each resolve to an inline assembler mov instruction. An empty finit_task has been added to i387.h to avoid linker errors in case the compiler still emits the call in init_fpu when CONFIG_MATH_EMULATION is not defined. The declaration of finit in i387.h has been removed as the remaining code using this function gets its prototype from fpu_proto.h. Signed-off-by:
