Linus Torvalds f06279ea19 powerpc fixes for 5.11 #7
A fix for a change we made to __kernel_sigtramp_rt64() which confused glibc's
 backtrace logic, and also changed the semantics of that symbol, which was
 arguably an ABI break.
 
 A fix for a stack overwrite in our VSX instruction emulation.
 
 A couple of fixes for the Makefile logic in the new C VDSO.
 
 Thanks to: Masahiro Yamada, Naveen N. Rao, Raoni Fassina Firmino, Ravi Bangoria.
