2007-11-30Fix kmem_cache_free performance regression in slabMatthew Wilcox
The database performance group have found that half the cycles spent in kmem_cache_free are spent in this one call to BUG_ON. Moving it into the CONFIG_SLAB_DEBUG-only function cache_free_debugcheck() is a performance win of almost 0.5% on their particular benchmark. The call was added as part of commit ddc2e812d592457747c4367fb73edcaa8e1e49ff with the comment that "overhead should be minimal". It may have been minimal at the time, but it isn't now.

2007-11-29x86/paravirt: revert exports to restore old behaviourJeremy Fitzhardinge
Subdividing the paravirt_ops structure caused a regression in certain non-GPL modules which try to use mmu_ops and cpu_ops. This restores the old behaviour, and makes it consistent with the non-CONFIG_PARAVIRT case. Takashi Iwai <tiwai@suse.de> adds: > I took at this problem (as I have an nvidia card on one of my > workstations), and found out that the following suffer from > EXPORT_SYMBOL_GPL changes: > > * local_disable_irq(), local_irq_save*(), etc. > * MSR-related macros like rdmsr(), wrmsr(), read_cr0(), etc. > wbinvd(), too. > * pmd_val(), pgd_val(), etc are all involved with pv_mm_ops. > pmd_large() and pmd_bad() is also indirectly involved. > __flush_tlb() and friends suffer, too. Christoph Hellwig objects to this patch on the grounds that modules shouldn't be using these operations anyway. I don't think this is a particularly good reason to reject the patch, for several reasons: 1. These operations are still available to modules when not using CONFIG_PARAVIRT, since they are implicitly exported as inline functions via the kernel headers. Exporting the same functionality as GPL-only symbols just adds a gratuitious difference between CONFIG_PARAVIRT and non-CONFIG_PARAVIRT configurations. If we really think these operations are not for module use (or non-GPL module use), then we should solve the problem in a general way. 2. It's a regression from previous kernels, which would work these modules even with CONFIG_PARAVIRT enabled. 3. The operations in question seem pretty reasonable for modules to use. The control registers/MSRs can be accessed directly anyway, so there's no benefit in preventing modules from using standard interfaces. And it seems reasonable to allow a graphics driver to create its own mappings if it wants. Therefore, I think this patch should go in for 2.6.24. If people really think that these operations should not be available to modules, then we can address that separately.

2007-11-29ACPI: avoid references to impossible processors.Christoph Lameter
ACPI uses NR_CPUS in various loops and in some it accesses per cpu data of processors that are not present(!) and that will never be present. The pointers to per cpu data are typically not initialized for processors that are not present. So we seem to be reading something here from offset 0 in memory. Make ACPI use nr_cpu_ids instead. That stops at the end of the possible processors. Convert one loop to NR_CPUS to use the cpu_possible map instead. That way ranges of processor that can never be brought online are skipped during the loop.

2007-11-29wait_task_stopped(): pass correct exit_code to wait_noreap_copyout()Scott James Remnant
In wait_task_stopped() exit_code already contains the right value for the si_status member of siginfo, and this is simply set in the non WNOWAIT case. If you call waitid() with a stopped or traced process, you'll get the signal in siginfo.si_status as expected -- however if you call waitid(WNOWAIT) at the same time, you'll get the signal << 8 | 0x7f Pass it unchanged to wait_noreap_copyout(); we would only need to shift it and add 0x7f if we were returning it in the user status field and that isn't used for any function that permits WNOWAIT.

Arrange the sections in the FRV arch so that a BRA instruction with a 16-bit displacement can always reach from the trap table to entry.S, tlb-miss.S and break.S. The problem otherwise is that the linker can insert sufficient code between the slots in the trap table and the targets of the branch instructions in those slots that the displacement field in the instruction isn't sufficiently large. This is because the branch targets were in the .text section along with most of the other code in the kernel.
