2.4.13-ac8 changed get_current() to use cr2 instead of esp and introduced hard_get_current() which uses esp. The comment on hard_get_current() in include/asm-i386/smp.h says "for within NMI, do_page_fault, cpu_init". But NMI, do_page_fault and cpu_init can execute other code, any references to current() in that other code will use get_current() instead of hard_get_current().
How is generic code called from NMI etc. meant to know which version of current() to use? Usage of current() is hidden inside a lot of other macros, this change looks like a data mismatch just waiting to bite us.
