Subject: [PATCH] bpftrace: Add s390x register support
Add s390x specific registers. This is needed for bpftrace builtins like argX,
regs(), retval etc. This commit provides various functions to perform proper
offset calculation from the pt_regs context. The builtin functions of
bpftrace uses these offset functions to generate the proper bytecode for s390x

Date: Thu, 28 May 2020 23:12:47 -0700
Subject: [PATCH] Remove RLIMIT_AS limit
We haven't seen any OOM issues in a while so I suspect either our type
fixes in bpftrace or upstream llvm changes have resolved the issue.
This closes #1355.
