            Bug ID: 30716
           Summary: On x86_64 get objtool warnings:  call to
                    __get_user_nocheck_1() with UACCESS enabled
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: runtime
          Assignee: systemtap at sourceware dot org
          Reporter: wcohen at redhat dot com
  Target Milestone: ---

With linux 6.x kernels the current git checkout of systemtap gets warnings =
like
the following on x86_64 machines:

../install/bin/stap --example -p4 stap_time.stp
/tmp/stapaDfnF3/stap_d27d31c04f7b6439f67d919b5ec15337_6499.o: warning: objt=
ool:
probe_54014+0xd4f: call to __get_user_nocheck_1() with UACCESS enabled
/home/wcohen/.systemtap/cache/d2/stap_d27d31c04f7b6439f67d919b5ec15337_6499=
.ko

This is introduced by systemtap git commit a9337abbb213e8.  If that particu=
lar
commit is removed the warning goes away.
