CMT#AB6351

When Correctable Error(CE) occurs in the CPU L3 cache in LinuxONE, db2sysc/gskit issues KMC instruction,
After recovering Correctable Error (CE),
HW recovery failed because KMC instruction could not rerun that original data was already encripted.
IPD Machine Check (error code “interrupt code 0x40000f5f40330000”) occurred and the Linux OS (one of the LPAR of LinuxONE) shut down.

As a request for improvement,
Even if KMC command is executed from db2sysc/gskit when Correctable Error (CE) occurs,
the HW recovery is completed normally (the KMC command rerun again) and processing continues.
