2005-07-27[PATCH] ppc64: dynamically allocate segment tablesDavid Gibson
PPC64 machines before Power4 need a segment table page allocated for each CPU. Currently these are allocated statically in a big array in head.S for all CPUs. The segment tables need to be in the first segment (so do_stab_bolted doesn't take a recursive fault on the stab itself), but other than that there are no constraints which require the stabs for the secondary CPUs to be statically allocated. This patch allocates segment tables dynamically during boot, using lmb_alloc() to ensure they are within the first 256M segment. This reduces the kernel image size by 192k... Tested on RS64 iSeries, POWER3 pSeries, and POWER5.

Typo bug that was using PCI1 defines instead of PCI2 when setting up the second PCI bus controller on 85xx based systems.

Call machine_shutdown() to move to the boot cpu and disable apics.

2005-07-22Remove "noreplacement" kernel command line option.Linus Torvalds
It is no longer valid to not replace instructions, since we depend on different behaviour depending on CPU capabilities.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.
2005-07-22x86: make restore_fpu() use alternative assembler instructionsLinus Torvalds
It's really just a single instruction, conditional on whether the CPU supports FXSR or not, so implement it as such instead of making it a function that queries FXSR dynamically. This means that the instruction just gets automatically rewritten to the correct one at boot-time.
