2008-10-13i386: convert hardware exception 7 to an interrupt gateAlexander van Heukelum
Handle no coprocessor exception with interrupt initially off. device_not_available in entry_32.S calls either math_state_restore or math_emulate. This patch adds an extra indirection to be able to re-enable interrupts explicitly in traps_32.c Signed-off-by: Alexander van Heukelum <heukelum@fastmail.fm> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2008-10-13i386: expand exception 3 DO_TRAP macroAlexander van Heukelum
The int3 exception was already takes as an interrupt and do_int3 does not fit in the new DO_ERROR macro. This patch just expands the DO_TRAP macro and rearranges the code a bit. No functional changes intended. Signed-off-by: Alexander van Heukelum <heukelum@fastmail.fm> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-10-13i386: convert hardware exception 0 to an interrupt gateAlexander van Heukelum
Handle divide error exception with interrupt initially off. Signed-off-by: Alexander van Heukelum <heukelum@fastmail.fm> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-10-13i386: prepare to convert exceptions to interruptsAlexander van Heukelum
There is some macro magic in traps_32.c to construct standard exception dispatch functions. This patch renames the DO_ERROR- like macros to DO_TRAP, and introduces new DO_ERROR ones that conditionally reenable interrupts explicitly, like x86_64. No code changes. Signed-off-by: Alexander van Heukelum <heukelum@fastmail.fm> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-10-13i386: remove kprobes' restore_interrupts in favour of conditional_stiAlexander van Heukelum
x86_64 uses a helper function conditional_sti in traps_64.c which is equal to restore_interrupts in kprobes.h. The only user of restore_interrupts is in traps_32.c. Introduce conditional_sti for i386 and remove restore_interrupts. Signed-off-by: Alexander van Heukelum <heukelum@fastmail.fm> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-10-13x86: rename discontig_32.c to numa_32.cYinghai Lu

2008-10-13arch/x86/kernel/smpboot.c: Clarify when irq processing begins.Manfred Spraul
Secondary cpus start with local interrupts disabled. start_secondary() first initializes the new cpu, then it enables the local interrupts. (although interrupts are enabled within smp_callin() as well). Right now, the local interrupts are enabled as a side effect of calling ipi_call_lock_irq(). The attached patch clarifies when local interrupts are enabled. Signed-off-by: Manfred Spraul <manfred@colorfullife.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-10-13x86-64: slightly stream-line 32-bit syscall entry codeJan Beulich
Avoid updating registers or memory twice as well as needlessly loading or copying registers. Signed-off-by: Jan Beulich <jbeulich@novell.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2008-10-12x86, early_ioremap: fix fencepost errorAlan Cox
The x86 implementation of early_ioremap has an off by one error. If we get an object which ends on the first byte of a page we undermap by one page and this causes a crash on boot with the ASUS P5QL whose DMI table happens to fit this alignment. The size computation is currently last_addr = phys_addr + size - 1; npages = (PAGE_ALIGN(last_addr) - phys_addr) (Consider a request for 1 byte at alignment 0...)
