2017-05-02x86/xen: use capabilities instead of fake cpuid values for acpiJuergen Gross1-8/+3
When running as pv domain xen_cpuid() is being used instead of native_cpuid(). In xen_cpuid() the acpi feature is indicated as not being present by special casing the related cpuid leaf in case we are not the initial domain. Instead of delivering fake cpuid values clear the cpu capability bit for acpi instead.

2017-05-02x86/xen: use capabilities instead of fake cpuid values for accJuergen Gross1-3/+1
When running as pv domain xen_cpuid() is being used instead of native_cpuid(). In xen_cpuid() the acc feature (thermal monitoring) is indicated as not being present by special casing the related cpuid leaf. Instead of delivering fake cpuid values clear the cpu capability bit for acc instead.

2017-05-02x86/xen: don't indicate DCA support in pv domainsJuergen Gross1-0/+1
Xen doesn't support DCA (direct cache access) for pv domains. Clear the corresponding capability indicator. Signed-off-by: Juergen Gross <[email protected]> Reviewed-by: Boris Ostrovsky <[email protected]> Signed-off-by: Juergen Gross <[email protected]>
2017-05-02xen: set cpu capabilities from xen_start_kernel()Juergen Gross1-7/+7
There is no need to set the same capabilities for each cpu individually. This can easily be done for all cpus when starting the kernel. Signed-off-by: Juergen Gross <[email protected]> Reviewed-by: Boris Ostrovsky <[email protected]> Signed-off-by: Juergen Gross <[email protected]>
2017-05-02x86/xen: split xen_smp_intr_init()/xen_smp_intr_free()Vitaly Kuznetsov1-0/+9
xen_smp_intr_init() and xen_smp_intr_free() have PV-specific code and as a praparatory change to splitting smp.c we need to split these fucntions. Create xen_smp_intr_init_pv()/xen_smp_intr_free_pv().
