    kdump.sysconfig.s390: Remove "prot_virt" from kdump kernel cmdline

    "prot_virt" enables the kernel to run Secure Execution virtual machines
    on s390. These virtual machines are isolated from the hypervisor and
    thus protected against tampering by a malicious host. Enabling
    "prot_virt" requires a minimum of ~2.5GB memory which exceeds what is
    typically reserved for the crashkernel. Thus remove "prot_virt" from the
    command line for the 2nd kernel to prevent it to run out-of-memory.

2b7d3aa34d Disable CMA in kdump 2nd kernel
Resolves: bz1950885
Upstream: fedora
Conflict: none

    Disable CMA in kdump 2nd kernel

    kexec-tools needs to disable CMA for kdump kernel cmdline,
    otherwise kdump kernel may run out of memory.

    This patch strips the inherited cma=, hugetlb_cma= cmd
    line from 1st kernel, and sets to be 0 for 2nd kernel.
