| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Update the UV address macros to better describe the fields of UV physical addresses. Improve comments in the header files.

| * | | i8259: fix final uglinessPavel Machek2008-06-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce IRQx_VECTOR on 32-bit, so that #ifdef noise is kept down. There should be no object code change. [ mingo@elte.hu: merged to x86/irq not x86/i8259 due to x86/irq having restructured the vector code into asm-x86/irq_vectors.h, which this patch touches. ] Signed-off-by: Pavel Machek <pavel@suse.cz> Signed-off-by: Ingo Molnar <mingo@elte.hu>
| * | | x86: rename the i8259_32/64.c leftovers to irqinit_32/64.cThomas Gleixner2008-05-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The leftovers of the i8259 unification have nothing to do with i8259 at all. They contain interrupt init code and the i8259_xx name is just misleading now. Rename them to irqinit_32/64.c Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

| * | | x86: automatical unification of i8259.cPavel Machek2008-05-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make conversion of i8259 very mechanical -- i8259 was generated by diff -D, with too different parts left in i8259_32 and i8259_64.c. Only "by hand" changes were removal of #ifdef from middle of the comment (prevented compilation) and removal of one static to allow splitting into files. Of course, it will need some cleanups now, and those will follow. Signed-of-by: Pavel Machek <pavel@suse.cz>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move the 4KSTACKS related code to one place.

| * | | i386: Execute stack overflow warning on interrupt stack v2Andi Kleen2008-05-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously the reporting printk would run on the process stack, which risks overflow an already low stack. Instead execute it on the interrupt stack. This makes it more likely for the printk to make it actually out. It adds one not taken test/branch more to the interrupt path when stack overflow checking is enabled. We could avoid that by duplicating more code, but that seemed not worth it.

Real suspend/resume support for AMD IOMMU is currently being worked on. Until this is ready it will be disabled to avoid data corruption when the IOMMU is not properly re-enabled at resume. The patch is based on a similar patch for the GART driver written by Pavel Machek. The overall driver merged into tip/master is tested with parallel disk and network loads and showed no problems in a test running for 3 days.
