| | | | | | | | | | | | | Here's the patch again to fix the code to handle if the values between MAX_USER_RT_PRIO and MAX_RT_PRIO are different. Without this patch, an SMP system will crash if the values are different.

* | Remove "noreplacement" kernel command line option.Linus Torvalds2005-07-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | It is no longer valid to not replace instructions, since we depend on different behaviour depending on CPU capabilities.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.
* | x86: make restore_fpu() use alternative assembler instructionsLinus Torvalds2005-07-22
| | | | | | | | | | | | | | | | | | 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.
* | Fix up incorrect "unlikely()" on %gs reload in x86 __switch_toLinus Torvalds2005-07-22
|/ | | | | | | | | | | These days %gs is normally the TLS segment, so it's no longer zero. As a result, we shouldn't just assume that %fs/%gs tend to be zero together, but test them independently instead. Also, fix setting of debug registers to use the "next" pointer instead of "current". It so happens that the scheduler will have set the new current pointer before calling __switch_to(), but that's just an implementation detail.

This is especially needed since 64-bit UMLs don't support 32-bit emulation for guest binaries, currently. This has been tested in all possible cases and works. Only exception is that I've built but not tested a 64-bit binary, because I hadn't a 64-bit filesystem available.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A big bug has been diagnosed on hosts running the SKAS patch and built with CONFIG_REGPARM, due to some missing prevent_tail_call(). On these hosts, this workaround is needed to avoid triggering that bug, because "to" is kept by GCC only in EBX, which is corrupted at the return of mmap2(). Since to trigger this bug int 0x80 must be used when doing the call, it rarely manifests itself, so I'd prefer to get this merged to workaround that host bug, since it should cause no functional change. Still, you might prefer to drop it, I'll leave this to you.

Instead hooks are used to fixup pci structures. This patch determines the nodes for Altix PCI busses. Remote Bridges: --------------- Altix supports remote I/O nodes without memory or processors but with bridges. The TIOCA type of bridge is an AGP bridge and the PROM provides information about the closest node. That information will be returned by pcibus_to_node. The TIOCP remote bridge type is a PCI bridge but the PROM does not provide a closest node id. pcibus_to_node will return -1 for devices on those bridges meaning that device control structures may be allocated on any node. Safeguard: ---------- Should the fixups result in invalid node information for a pci controller then a warning will be printed and pcibus_to_node will return -1. This patch also fixes the "FIXME" in sn_dma_alloc_coherent. This means that dma_alloc_coherent will now use alloc_pages_node to allocate memory local to the node that the PCI device is connected to.
