traps: x86: finalize unification of traps.c

2008-10-13T08:33:29Z

traps_32.c and traps_64.c are now equal. Move one to traps.c, delete the other one and change the Makefile Signed-off-by: Alexander van Heukelum Signed-off-by: Ingo Molnar

traps: x86: make traps_32.c and traps_64.c equal

2008-10-13T08:33:28Z

Use CONFIG_X86_64/CONFIG_X86_32 to condtionally compile the parts needed for x86_64 or i386 only. Runs a small userspace for a number of minimal configurations and boots the defconfigs. Signed-off-by: Alexander van Heukelum Signed-off-by: Ingo Molnar

traps: x86: various noop-changes preparing for unification of traps_xx.c

2008-10-13T08:33:27Z

- reordering include files - whitespace changes - comment changes - removed unused bad_intr() - make default_do_nmi static Signed-off-by: Alexander van Heukelum Signed-off-by: Ingo Molnar

traps: x86_64: use task_pid_nr(tsk) instead of tsk->pid in do_general_protection

2008-10-13T08:33:26Z

Use task_pid_nr(tsk) instead of tsk->pid in do_general_protection. Signed-off-by: Alexander van Heukelum Signed-off-by: Ingo Molnar

traps: x86_64: make io_check_error equal to the one on i386

2008-10-13T08:33:24Z

Make io_check_error equal to the one on i386. Signed-off-by: Alexander van Heukelum Signed-off-by: Ingo Molnar

traps: x86_64: make math_state_restore more like i386

2008-10-13T08:33:22Z

- rename variable me -> tsk - get thread and tsk like i386 - expand used_math() - copy comment Signed-off-by: Alexander van Heukelum Signed-off-by: Ingo Molnar

traps: x86: converge trap_init functions

2008-10-13T08:33:22Z

- set_system_gate on i386 is really set_system_trap_gate - set_system_gate on x86_64 is really set_system_intr_gate - ist=0 means no special stack switch is done: - introduce STACKFAULT_STACK, DOUBLEFAULT_STACK, NMI_STACK, DEBUG_STACK and MCE_STACK as on x86_64. - use the _ist variants with XXX_STACK set to zero - remove set_system_gate Signed-off-by: Alexander van Heukelum Signed-off-by: Ingo Molnar traps: x86: correct copy/paste bug: a trap is a GATE_TRAP Fix copy/paste/forgot-to-edit bug in desc.h. Signed-off-by: Alexander van Heukelum Signed-off-by: Ingo Molnar

x86, traps: converge do_debug handlers

2008-10-13T08:33:21Z

Make the x86_64-version and the i386-version of do_debug more similar. - introduce preempt_conditional_sti/cli to i386. The preempt-count is now elevated during the trap handler, like on x86_64. It does not run on a separate stack, however. - replace an open-coded "send_sigtrap" - copy some comments Signed-off-by: Alexander van Heukelum Signed-off-by: Ingo Molnar

x86, traps: introduce dotraplinkage

2008-10-13T08:33:20Z

Mark the exception handlers with "dotraplinkage" to hide the calling convention differences between i386 and x86_64. Signed-off-by: Alexander van Heukelum Signed-off-by: Ingo Molnar

x86, traps: split out math_error and simd_math_error

2008-10-13T08:33:18Z

Split out math_error from do_coprocessor_error and simd_math_error from do_simd_coprocessor_error, like on i386. While at it, add the "error_code" parameter to do_coprocessor_error, do_simd_coprocessor_error and do_spurious_interrupt_bug. This does not change the generated code, but brings the declarations in line with all the other trap handlers. Signed-off-by: Alexander van Heukelum Signed-off-by: Ingo Molnar
