lib-y is the new way to define what objects belongs to a library. The implementation was not made backwards compatible and therefore an update to all architectures are needed. This is a simple replacement of obj-* to lib-* and deletion of L_TARGET. The new mechanish where lib.a can be mixed with built-in.o is not utilised.

One of the goals of the whole new modversions implementation: export-objs is gone for good!

x86-64 updates for 2.5.58. Changes only x86-64 specific files. - Rewrote module allocation. Lots of bugs fixed. Module loading should work now again. - Kconfig help fixes from Randy Dunlap - Makefile cleanups from Pavel Machek and Sam Ravnborg - Assembly cleanups from Pavel - defconfig update - Better strlen_user/strnlen_user - Merge with i386: new ptrace commands, 32bit vsyscall signal trampolines new deactivate_mm, add asm/bug.h - Make sure initramfs is freed after booting (thanks to Kai for the hint) - User per cpu data for profile counters (Ravikiran Thirumalai) - 32bit compat_* updates from Stephen Rothwell - Fix race in context switch. The exception handler for bogus segment loads in __switch_to needs to keep interrupts disabled, otherwise an interrupt can deadlock on scheduler locks. Also make sure they don't printk or set oops_in_progress during printk because printk does a wake_up too. - Disable 64bit GS base changes for processes. I cannot get it to work reliably. - Clear IOPL on kernel entry

Makefiles no longer need to include Rules.make, which is currently an empty file. This patch removes it from the arch tree Makefiles.

x86_64 core updates. - Make it compile again (switch_to macros etc., add dummy suspend.h) - reenable strength reduce optimization - Fix ramdisk (patch from Mikael Pettersson) - Some merges from i386 - Reimplement lazy iobitmap allocation. I reimplemented it based on bcrl's idea. - Fix IPC 32bit emulation to actually work and move into own file - New fixed mtrr.c from DaveJ ported from 2.4 and reenable it. - Move tlbstate into PDA. - Add some changes that got lost during the last merge. - new memset that seems to actually work. - Align signal handler stack frames to 16 bytes. - Some more minor bugfixes.

Here is the big 2.5.21 x86-64 sync patch. It only touches arch/x86_64 and include/asm-x86_64. It requires a few other changes that I'm sending in separate mail. Changes: - merge wit 2.5.21 - merge from 2.5.21/i386 (new PCI code, new LDT code etc.) - sync with 2.4-x86_64 tree. - minor updates to 32bit emulation - better early console; including serial support. - now set up dummy PDA for booting to avoid problems - Fix GS reloading in context switch one instruction race - Remove hardcoded names from mpparse code - Fix inline assembly for RAID-5 xor (similar change needed for i386) - Real per cpu data support based on PDA field - Cleanup of offset.c generation requested by Kai: it only puts structure offsets into offset.h now. - Fix i387 fxsave signal frame problems. - Add uname emulation via personality ("linux32") - New SSE optimized checksum-copy, copy*user, memcpy, clear_page, copy_page functions. Other tunings/cleanups in checksum and other user memory access function. - check if exception table is really sorted - Cleanups in page table handling in preparation of non executable pages support. - Cleanup PDA access to not require offset.h (thanks to kai for kicking me to this) - use long long for u64/s64 to avoid more warnings - remove CONFIG_ISA - fix various bugs and other cleanups

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
