-Subject: [PATCH] Add %esp to list of clobbered registers
-
-GCC assumes that it can combine stacks from
-outer
-    grub_stage2()
-and inner
-    trampoline doit()
-functions (optimisation -fcombine-stack-adjustments).
-
-But doit() function clobbers %esp in inline
-assebly statement as:
-
-  asm volatile ("movl %%esp, %0\n\tmovl %1, %%esp\n"
-               : "=&r" (realstack) : "r" (simstack));
-
-which tricks gcc into computing invalid local variable
-offsets from current %esp value.
-
-Fix by hinting gcc about %esp change in clobber list.
