Linus Torvalds 74a0032b85 - Prepare for and clear .brk early in order to address XenPV guests 
failures where the hypervisor verifies page tables and uninitialized
 data in that range leads to bogus failures in those checks
 
 - Add any potential setup_data entries supplied at boot to the identity
 pagetable mappings to prevent kexec kernel boot failures. Usually, this
 is not a problem for the normal kernel as those mappings are part of
 the initially mapped 2M pages but if kexec gets to allocate the second
 kernel somewhere else, those setup_data entries need to be mapped there
 too.
 
 - Fix objtool not to discard text references from the __tracepoints
 section so that ENDBR validation still works
 
 - Correct the setup_data types limit as it is user-visible, before 5.19
 releases
