Commitf388f60ca9("x86/cpu: Drop configuration options for early 64-bit CPUs") removes the config symbols MCORE2 and MK8. With that, the references to those two config symbols in xen's x86 Kconfig are obsolete. Drop them.

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".
