Apart from the # practical implications, __kernel_sigtramp_rt64() was a VDSO function # with the semantics that it is a function you can call from userspace # to end a signal handling. Now this semantics are no longer valid. # # I believe the aforementioned change affects all releases since 5.9. # # This patch tries to fix both the semantics and practical aspect of # __kernel_sigtramp_rt64() returning it to the previous code, whilst # keeping the intended behaviour of 0138ba5783ae by adding a new symbol # to serve as the jump target from the kernel to the trampoline. Now the # trampoline has two parts, a new entry point and the old return point. # # [1] https://lists.ozlabs.org/pipermail/linuxppc-dev/2021-January/223194.html # # Fixes: 0138ba5783ae
