This patch brings 2.5.8 in sync with the x86-64 2.4 development tree again (excluding device drivers) It has lots of bug fixes and enhancements. It only touches architecture specific files. - Sync with 2.5.8 - SMP/APIC supported now. - Module loading works now. - Time keeping bugs fixed. - entry.S streamlined and some bugs fixed. - modify_ldt works now - mostly rewritten FPU support (including FXRSTOR for initial FPU initialization based on the initial state) - 32bit emulation enhanced and bugs fixed. - rewrote mm initialization and lots of cleanups in the page table handling __PAGE_OFFSET is now moved to 0x10000000000 and some vmalloc/ioremap problems have been fixed. They have an own PML4 slot now. - WCHAN reporting support for RIP (but not RSP) - Lots of various other bug fixes and cleanups. Currently broken: - ACPI - MTRR It needs some other bugfixes outside architecture specific code. I sent them all in separate mail.

This adds the x86_64 arch and asm directories and a Documentation/x86_64. It took a bit longer because I first had to make preemption and thread_info work and also found some other bugs while doing this. The port has been tested for a long time on UP. I'm not sure what I should describe. A lot is based on i386 with a lot of cleanups. I wrote a paper about it for last year's OLS that describes most of the changes (ftp://ftp.firstfloor.org/pub/ak/x86_64.ps.gz). It is a bit outdated now, but should give a good overview. It currently has a completely cut'n'pasted from others+hacked 32bit emulation. I hope to clean that up in the future by merging the generic core of this with other 64bit archs. Thanks, -Andi
