2011-01-13x86: support XZ-compressed kernelLasse Collin5-7/+11
This integrates the XZ decompression code to the x86 pre-boot code. mkpiggy.c is updated to reserve about 32 KiB more buffer safety margin for kernel decompression. It is done unconditionally for all decompressors to keep the code simpler. The XZ decompressor needs around 30 KiB of heap, so the heap size is increased to 32 KiB on both x86-32 and x86-64. Documentation/x86/boot.txt is updated to list the XZ magic number. With the x86 BCJ filter in XZ, XZ-compressed x86 kernel tends to be a few percent smaller than the equivalent LZMA-compressed kernel. Signed-off-by: Lasse Collin <lasse.collin@tukaani.org> Cc: "H.

2011-01-13rapidio: fix hang on RapidIO doorbell queue full conditionThomas Taranowski1-1/+0
In fsl_rio_dbell_handler() the code currently simply acknowledges the QFI queue full interrupt, but does nothing to resolve the queue full condition. Instead, it jumps to the end of the isr. When a queue full condition occurs, the isr is then re-entered immediately and continually, forever. The fix is to just fall through and read out current doorbell entries.

Drop the old geode_gpio crud, as well as the raw outl() calls; instead, use the Linux GPIO API where possible, and the cs5535_gpio API in other places. Note that we don't actually clean up the driver properly yet (once loaded, it always remains loaded). That'll come later.. This patch is necessary for building the driver.

2011-01-13kernel: clean up USE_GENERIC_SMP_HELPERSAmerigo Wang2-9/+2
For arch which needs USE_GENERIC_SMP_HELPERS, it has to select USE_GENERIC_SMP_HELPERS, rather than leaving a choice to user, since they don't provide their own implementions. Also, move on_each_cpu() to kernel/smp.c, it is strange to put it in kernel/softirq.c. For arch which doesn't use USE_GENERIC_SMP_HELPERS, e.g. blackfin, only on_each_cpu() is compiled.

Occasionally the system gets into a state where the CMOS clock has gotten slightly ahead of current time and the periodic update of RTC fails. The message is a nuisance and repeats spamming the log. See: http://www.ntp.org/ntpfaq/NTP-s-trbl-spec.htm#Q-LINUX-SET-RTC-MMSS Rather than just removing the message, make it show only once and reduce severity since it indicates a normal and non urgent condition.

2011-01-12KVM: MMU: audit: allow audit more guests at the same timeXiao Guangrong3-30/+39
It only allows to audit one guest in the system since: - 'audit_point' is a glob variable - mmu_audit_disable() is called in kvm_mmu_destroy(), so audit is disabled after a guest exited this patch fix those issues then allow to audit more guests at the same time Signed-off-by: Xiao Guangrong <xiaoguangrong@cn.fujitsu.com> Signed-off-by: Avi Kivity <avi@redhat.com>
2011-01-12KVM: Fetch guest cr3 from hardware on demandAvi Kivity5-6/+23
Instead of syncing the guest cr3 every exit, which is expensince on vmx with ept enabled, sync it only on demand. [sheng: fix incorrect cr3 seen by Windows XP] Signed-off-by: Sheng Yang <sheng@linux.intel.com> Signed-off-by: Avi Kivity <avi@redhat.com>
2011-01-12KVM: Replace reads of vcpu->arch.cr3 by an accessorAvi Kivity5-20/+27
This allows us to keep cr3 in the VMCS, later on. Signed-off-by: Avi Kivity <avi@redhat.com>
2011-01-12KVM: MMU: only write protect mappings at pagetable levelMarcelo Tosatti1-0/+3
If a pagetable contains a writeable large spte, all of its sptes will be write protected, including non-leaf ones, leading to endless pagefaults. Do not write protect pages above PT_PAGE_TABLE_LEVEL, as the spte fault paths assume non-leaf sptes are writable.

2011-01-12KVM: VMX: Optimize atomic EFER loadAvi Kivity1-0/+30
When NX is enabled on the host but not on the guest, we use the entry/exit msr load facility, which is slow. Optimize it to use entry/exit efer load, which is ~1200 cycles faster. Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>

2011-01-12KVM: SVM: copy instruction bytes from VMCBAndre Przywara8-15/+26
In case of a nested page fault or an intercepted #PF newer SVM implementations provide a copy of the faulting instruction bytes in the VMCB. Use these bytes to feed the instruction emulator and avoid the costly guest instruction fetch in this case.

2011-01-12KVM: SVM: implement enhanced INVLPG interceptAndre Przywara1-1/+6
When the DecodeAssist feature is available, the linear address is provided in the VMCB on INVLPG intercepts. Use it directly to avoid any decoding and emulation. This is only useful for shadow paging, though. Signed-off-by: Andre Przywara <andre.przywara@amd.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
2011-01-12KVM: SVM: enhance mov DR intercept handlerAndre Przywara1-16/+40
Newer SVM implementations provide the GPR number in the VMCB, so that the emulation path is no longer necesarry to handle debug register access intercepts. Implement the handling in svm.c and use it when the info is provided. Signed-off-by: Andre Przywara <andre.przywara@amd.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>

2011-01-12KVM: cleanup emulate_instructionAndre Przywara5-22/+28
emulate_instruction had many callers, but only one used all parameters. One parameter was unused, another one is now hidden by a wrapper function (required for a future addition anyway), so most callers use now a shorter parameter list.
