[PATCH v6 47/76] x86/dumpstack/64: Add noinstr version of get_stack_info()

From: Joerg Roedel The get_stack_info functionality is needed in the entry code for the #VC exception handler. Provide a version of it in the .text.noinstr section which can be called safely from there. Signed-off-by: Joerg Roedel Link: https://lore.kernel.org/r/20200724160336.5435-47-j...@8byt
