drmgr/pmig: remove deprecated call to refrsrc IBM.ManagementServer
As Nathan reported while reviewing this series:
This RSCT doc indicates that the IBM.ManagementServer resource class has
been superseded:
https://www.ibm.com/docs/en/rsct/3.2?topic=security-management-domain-configuration
Removing that deprecated call in this series because it is conflicting with
a following patch. The system returned value is stored in rc to prevent
compilation error (due to warning if system returned value is not read).

+.TH DRMGR-HOOKS 8 "May 24, 2022" Linux "Linux on Power Service Tools"
+.SH NAME
+drmgr\-hooks \- Hooks run by drmgr
+.SH DESCRIPTION
+When
+.B drmgr
+is run to perform PowerVM Dynamic Logical Partitioning (DLPAR) operations,
+a set of hooks may be triggered to validate, and, or be aware of the incoming operation.
+.P
+Not all the DLPAR operations are providing hook calls.
+Currently only the LPAR Migration operation (LPM) is concerned.
+.P
+The hooks are executable files stored in a directory named "DRC TYPE" in
+.IR /etc/drmgr.d/ .
+For instance, hooks run when a LPAR migration is done are stored in
+.IR /etc/drmgr.d/pmig .
+.P
+Hook files can be symbolic links to executable files. All the hooks can be stored in
+.IR /etc/drmgr.d
+and linked into multiple directories to provide multiple DRC type's hooks.
+.SH ARGUMENTS
+.P
+Hooks are called without any arguments but with at least these 2 environment variable set:
+.TP
+.BI "DRC_TYPE"
+The Dynamic reconfiguration connector type to act upon from the following list:
+.BR pmig ", " pci ", " cpu ", " mem ", " port ", " slot ", " phb "."
+.TP
+.BI "PHASE"
+The phase of the operation from the following list:
+.BR check ", " undocheck ", " pre ", " post "."
+.SH LPAR MIGRATION
+.P
+When a LPAR migration is initiated the
+.B check
+phase is first triggered. Hooks called at check phase may returned a non zero value to prevent the migration operation to happen.
+The error messages displayed in
+.BR STDOUT " or " STDERR
+would be reported to the end user through the HMC.
+.P
+If the
+.B check
+phase has failed, because at least one hook has returned a non null value, the
+.B undocheck
+phase is launched. Return value for the
+.B
+undocheck
+phase is ignored.
+.P
+If the
+.B check
+phase succeeded, the
+.BR pre " and later " post
+phases are triggered. Returned values for these 2 phases are ignored, and the
+.B post
+phase is triggered even if the LPM operation has failed.
+.SH ENVIRONMENT
+.P
+The drmgr's hooks are called while holding the DLPAR lock, so any other
+DLPAR operation initiated from a hook is expected to fail.
+.P
+The hooks standard input
+.B STDIN
+is redirected to
+.I /dev/null
+while STDOUT and STDERR are redirected to pipes.
+The outputs done in these pipes are reported to the end user when a hook has returned an error value and that error value is not ignored (e.g in the LPM, the
+.B check
+phase but not the
+.BR pre "or " post
+phase)
+.P
+Except the variables specified in the ARGUMENTS section, all the environment variables are unset before calling the hook.

drmgr: introducing the LPM hooks
There are 3 hooks run when an LPM is performed:
1. check before the LPM is really initiated
1 bis. undocheck if check failed.
2. pre just before entering the switch over
3. post at the end of the LPM operation
Only the check hook's return status is taken in account. If the check hook
return value is different from 0, the LPM is aborted and the outputs of the
check hook are reported to the end user through the HMC.
In the case at least one check hook returned a non zero status, the
undocheck event is run (for all the hooks), and the pre and post events are
not triggered.
The post event is triggered even if the LPM operation has failed.

drmgr: introducing the hook framework
The hook framework run in a sequence any executable file found in the
relevant directory (/etc/drmgr.d/<DRC TYPE NAME>/)
The hook are run according to the versionsort()'s output order.
The hook inherits from drmgr its standard I/O streams. All others file
descriptor should have the close on exec flag set to ensure they will be
closed when executing an hook.
The hooks are run with no arguments, arguments are passed through
environment variable.
The inherited environment is cleaned and 2 environment variables
are set:
- DRC_TYPE containing the DRC type string
- PHASE containing the current phase
There are 4 known phases: check, undocheck, pre and post.
The hook's run is recorded in the drmgr's log, so blocking hook could be
identified.

drmgr: prevent file descriptor to be inherited when execing a child
When a file descriptor is opened and remain opened, the O_CLOEXEC should be
set so execed children are not inheriting it.
There is no need for file descriptor opened and closed immediately, like in
probe_cpu().

ppc64_cpu: Support partial SMT level through SYS FS smt/control files
The next kernel release will support partial SMT level [1] though the SYS
FS file "devices/system/cpu/smt/control". This allows the SMT level to be
recorded in the kernel. With the current SMT level stored in the kernel,
when a new CPU is added, only the necessary threads are brought online.
The legacy way to active threads through the SYS FS files
'devices/system/cpu/cpu<n>/online', is still used in the case the new SYS
FS API is not available. This allows compatibility with the previous kernel
versions.
