Main changes are: - Merge CPU_LOONGSON1B and CPU_LOONGSON1C into a unified CPU_LOONGSON32, as both are based on the GS232 core. - Consolidate LOONGSON1_LS1B and LOONGSON1_LS1C Kconfig options into MACH_LOONGSON32. - Enable MACH_GENERIC_CORE and remove the legacy custom implementation. - Remove all Loongson-1 platform devices and associated code, which are now obsolete due to Device Tree support. - Misc cleanup.

Trigger a warning if something registers it twice as to catch bugs before they are found by things just not working as expected. - Make DYNAMIC_FTRACE always enabled for architectures that support it As static ftrace (where all functions are always traced) is very expensive and only exists to help architectures support ftrace, do not make it an option. As soon as an architecture supports DYNAMIC_FTRACE make it use it. This simplifies the code. - Remove redundant config HAVE_FTRACE_MCOUNT_RECORD The CONFIG_HAVE_FTRACE_MCOUNT was added to help simplify the DYNAMIC_FTRACE work, but now every architecture that implements DYNAMIC_FTRACE also has HAVE_FTRACE_MCOUNT set too, making it redundant with the HAVE_DYNAMIC_FTRACE. - Make pid_ptr string size match the comment In print_graph_proc() the pid_ptr string is of size 11, but the comment says /* sign + log10(MAX_INT) + '\0' */ which is actually 12. * tag 'ftrace-v6.17' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: tracing: Remove redundant config HAVE_FTRACE_MCOUNT_RECORD ftrace: Make DYNAMIC_FTRACE always enabled for architectures that support it fgraph: Keep track of when fgraph_ops are registered or not fgraph: Make pid_str size match the comment
