* x86: fix EFI mappingHuang, Ying2008-02-042-38/+41
| | | | | | | | | The patch updates EFI runtime memory mapping code, by making EFI areas explicitly executable. Signed-off-by: Huang Ying <ying.huang@intel.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
* x86: no CPA on iounmapThomas Gleixner2008-02-041-3/+0
| | | | | | | | | When an ioremap is unmapped, do not change the page attributes. There might be another mapping of the same physical address. PAT might detect a conflicting mapping attribute for no good reason. The mapping is removed anyway. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86: ioremap remove the range check of cpaThomas Gleixner2008-02-041-15/+2
| | | | | | | | Now that cpa works on non-direct mappings as well, we can safely remove the range check in ioremap_change_attr(). Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Ingo Molnar <mingo@elte.hu>

* x86: CPA use the existing pfn in split as wellThomas Gleixner2008-02-041-4/+7
| | | | | | | | | | When splitting large pages, we ge the pfn from the existing entry instead of calculating it ourself. This removes the last remaining range restriction of the cpa code. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86: use the pfn from the page when change its attributesArjan van de Ven2008-02-041-14/+17
| | | | | | | | | | | | | | | When changing the attributes of a pte, we should use the PFN from the existing PTE rather than going through hoops calculating what we think it might have been; this is both fragile and totally unneeded. It also makes it more hairy to call any of these functions on non-direct maps for no good reason whatsover. With this change, __change_page_attr() no longer takes a pfn as argument, which simplifies all the callers.

* x86: teach the static_protection function about high mappingsArjan van de Ven2008-02-041-4/+31
| | | | | | | | | | | | | | | Right now, enforcing that the high mapping of the kernel text doesn't get the NX bit is done deep in the guts of CPA, rather than in the static_protection() function that enforces all other per-arch sanity checks. This patch moves this sanity check into the central static_protection() function instead, and makes it apply ONLY to the kernel text, not to all other areas in the high mapping.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Avoid section mismatch involving arch_register_cpu. Marking arch_register_cpu as __init and removing the export for non-hotplug-cpu configurations makes the following warning go away: Section mismatch in reference from the function arch_register_cpu() to the function .devinit.text:register_cpu() The function arch_register_cpu() references the function __devinit register_cpu(). This is often because arch_register_cpu lacks a __devinit annotation or the annotation of register_cpu is wrong. The only external user of arch_register_cpu in the tree is in drivers/acpi/processor_core.c where it is guarded by ACPI_HOTPLUG_CPU (which depends on HOTPLUG_CPU).
