arm64: report CPU number in bad_mode
If we take an exception we don't expect (e.g. SError), we report this in the bad_mode handler with pr_crit. Depending on the configured log level, we may or may not log additional information in functions called subsequently. Notably, the messages in dump_stack (including the CPU number) are printed with KERN_DEFAULT and may not appear. Some exceptions have an IMPLEMENTATION DEFINED ESR_ELx.ISS encoding, and knowing the CPU number is crucial to correctly decode them. To ensure that this is always possible, we should log the CPU number along with the ESR_ELx value, so we are not reliant on subsequent logs or additional printk configuration options. This patch logs the CPU number in bad_mode such that it is possible for a developer to decode these exceptions, provided access to sufficient documentation.
