Remove "noreplacement" kernel command line option.

2005-07-22T22:29:40Z

It is no longer valid to not replace instructions, since we depend on different behaviour depending on CPU capabilities. If you need to limit the capabilities of the replacements (because the boot CPU has features that non-boot CPU's do not have, for example), you need to explicitly disable those capabilities that are not shared across all CPU's. For example, if your boot CPU has FXSR, but other CPU's in your system do not, you need to use the "nofxsr" kernel command line, not disable instruction replacement per se.

[PATCH] Retrieve elfcorehdr address from command line

[PATCH] kdump: Retrieve saved max pfn

2005-06-25T23:24:52Z

This patch retrieves the max_pfn being used by previous kernel and stores it in a safe location (saved_max_pfn) before it is overwritten due to user defined memory map. This pfn is used to make sure that user does not try to read the physical memory beyond saved_max_pfn. Signed-off-by: Vivek Goyal Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] crashdump: x86 crashkernel option

2005-06-25T23:24:50Z

This is the x86 implementation of the crashkernel option. It reserves a window of memory very early in the bootup process, so we never use it for anything but the kernel to switch to when the running kernel panics. In addition to reserving this memory a resource structure is registered so looking at /proc/iomem it is clear what happened to that memory. ISSUES: Is it possible to implement this in a architecture generic way? What should be done with architectures that always use an iommu and thus don't report their RAM memory resources in /proc/iomem?

[PATCH] kexec: reserve Bootmem fix for booting nondefault location kernel

2005-06-25T23:24:48Z

This patch fixes a problem with reserving memory during boot up of a kernel built for non-default location. Currently boot memory allocator reserves the memory required by kernel image, boot allocaotor bitmap etc. It assumes that kernel is loaded at 1MB (HIGH_MEMORY hard coded to 1024*1024). But kernel can be built for non-default locatoin, hence existing hardcoding will lead to reserving unnecessary memory. This patch fixes it.

[PATCH] kexec: x86: local apic fix

2005-06-25T23:24:46Z

From: "Maciej W. Rozycki" Fix a kexec problem whcih causes local APIC detection failure. The problem is detect_init_APIC() is called early, before the command line have been processed. Therefore "lapic" (and "nolapic") have not been seen, yet. Signed-off-by: Maciej W. Rozycki Signed-off-by: Eric Biederman Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] init call cleanup

[PATCH] acpi build fix: x86 setup.c

2005-05-31T21:54:17Z

This is a neverending story linux/acpi.h contains empty declarations for acpi_boot_init() & acpi_boot_table_init() but they are nested inside #ifdef CONFIG_ACPI.
