Subject: [PATCH] s390/sclp: fix SCLP facility map
|
||
|
|
|
||
|
|
cheery-pick from 81f993828bce9a9afd72da17b7672cb8bd121e63
|
||
|
|
|
||
|
|
Qemu's SCLP implementation incorrectly reports that it supports CPU
|
||
|
|
reconfiguration. If a guest issues a CPU reconfiguration request it
|
||
|
|
is rejected as invalid command.
|
||
|
|
|
||
|
|
Fix the SCLP_HAS_CPU_INFO mask, and remove the unused
|
||
|
|
SCLP_CMDW_CONFIGURE_CPU and SCLP_CMDW_DECONFIGURE_CPU defines.
