[MLIR][NVVM]Import llvm intrinsics for nvvm.barrier (#202862)
This PR adds LLVM IR import support for the `bar.sync` intrinsic family,
lifting the four variants into `nvvm.barrier` with the appropriate
`aligned` attribute and optional thread-count operand.
`LLVM_IntrOpBase` and its auto-generated import is one to one, but four
`bar.sync` variants are many-to-one, where they all lift into
`nvvm.barrier`, differing only in `aligned` and the optional
`numberOfThreads` operand.
An alternative implementation would extend mlir-tblgen with many-to-one
intrinsic-to-op mapping support so the conversion could live in
`NVVMOps.td`. But the change is bigger than manually import `bar.sync`
intrinsic family.
gss_impl.c: Fix a nfsd hang when the kgssapi.ko is loaded, but no gssd
After the conversion to using netlink, the kgssapi had
no way of knowing if the gssd daemon was running.
As such, a boot where the kgssapi is loaded, but the
gssd is not enabled would hang the nfsd for a very
long time. (Many timeouts at 300sec each.)
This patch adds a Null RPC upcall with a 200msec
timeout to check to see if the gssd is running.
If the gssd is not running, the nfsd starts up
(without Kerberos support) with only a 200msec
delay.)
Also, move the svc_svc_nl_create() and svc_reg() calls in gssd.c
to before the daemon() call, so they are guaranteed to have
been done before the nfsd(8) daemon is started by
the rc scripts.

[M68K][GlobalISel] Remove dependency on legal ruleset (#207614)
This fills in always legal rules, to remove the dependency on the legacy
ruleset. This is not guaranteed to be all the rules, just the ones that
appear
in tests.
See #197308
retire the cpp.sh script and install the cpp binary directly in /usr/bin
The cpp.sh wrapper script no longer serves any purpose:
* We no longer force the preprocessor into -traditional mode.
* Our compilers already define __GNUC__ for the preprocessor.
* The location of cpp is well known.
* Our compilers only use the standard include paths by default.

[OpenMPOpt] Null generic-mode wrappers for SPMDized kernels
If a kernel gets SPMDized, it doesn't need the wrapper function that is
passed to __kmpc_parallel_60. Keeping the dead wrapper function can lead
to lots of misleading "local memory global used by non-kernel function"
AMDGPU backend warnings.
Let OpenMPOpt null the wrapper argument such that DCE can then remove
the corresponding dead functions.
