* x86: remove 8254 timer texts from DocumentationLuiz Fernando N. Capitulino2008-08-281-4/+0
| | | | | | | | | | | | | | Commit ecd29476ae0143b1c3641edfa76c0fc3e9ad3021 removed the "disable_8254_timer" and "enable_8254_timer" kernel parameters from the kernel but did not remove the references to them from two files in the Documentation directory: kernel-parameters.txt and x86/x86_64/boot-options.txt. This change completes the removal. Signed-off-by: Luiz Fernando N. Capitulino <lcapitulino@mandriva.com.br> Acked-by: Maciej W.

* x86 boot: only pick up additional EFI memmap if add_efi_memmap flagPaul Jackson2008-07-081-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Applies on top of the previous patch: x86 boot: add code to add BIOS provided EFI memory entries to kernel Instead of always adding EFI memory map entries (if present) to the memory map after initially finding either E820 BIOS memory map entries and/or kernel command line memmap entries, -instead- only add such additional EFI memory map entries if the kernel boot option: add_efi_memmap is specified. Requiring this 'add_efi_memmap' option is backward compatible with kernels that didn't load such additional EFI memory map entries in the first place, and it doesn't override a configuration that tries to replace all E820 or EFI BIOS memory map entries with ones given entirely on the kernel command line.

| * x86: move x86-specific documentation into Documentation/x86H. Peter Anvin2008-05-3012-0/+1754
|/ | | | | | | | | | | The current organization of the x86 documentation makes it appear as if the "i386" documentation doesn't apply to x86-64, which is does. Thus, move that documentation into Documentation/x86, and move the x86-64-specific stuff into Documentation/x86/x86_64 with the eventual goal to move stuff that isn't actually 64-bit specific back into Documentation/x86.
