Pull x86 paravirt updates from Ingo Molnar:
"Two main changes:
- Remove no longer used parts of the paravirt infrastructure and put
large quantities of paravirt ops under a new config option
PARAVIRT_XXL=y, which is selected by XEN_PV only. (Joergen Gross)
- Enable PV spinlocks on Hyperv (Yi Sun)"

Limit paravirtualized user domains to 512GB of RAM.
|
|
|
|
The Xen tools and crash dump analysis tools might not support
|
|
pv-domains with more than 512 GB of RAM. This option controls the
|
|
default setting of the kernel to use only up to 512 GB or more.
|

It is always possible to change the default via specifying the
|
|
boot parameter "xen_512gb_limit".
