Merge branch 'upstream' of git://ftp.linux-mips.org/pub/scm/upstream-…

…linus * 'upstream' of git://ftp.linux-mips.org/pub/scm/upstream-linus: [MIPS] Update defconfigs. [MIPS] Separate CPU entries in /proc/cpuinfo with a blank line. [MIPS] sys_mmap2 offset argument should always be shifted 12, not PAGE_SHIFT. [MIPS] TX49XX has prefetch. [MIPS] Kill tlb-andes.c. [MIPS] War on whitespace: cleanup initial spaces followed by tabs. [MIPS] Makefile crapectomy. [MIPS] Reformat __xchg(). [MIPS] Mention Broadcom part number for BigSur board [MIPS] Remove CONFIG_BUILD_ELF64. [MIPS] Further sparsification for 32-bit compat code. [MIPS] fix wrong __user usage in _sysn32_rt_sigsuspend [MIPS] Signal cleanup [MIPS] Reformat all of signal32.c with tabs instead of space for consistency [MIPS] Delete unused sys32_waitpid. [MIPS] Make I/O helpers more customizable [MIPS] Symmetric Uniprocessor support for Qemu. [MIPS] sc-rm7k.c cleanup [MIPS] MIPS64 R2 optimizations for 64-bit endianess swapping. [MIPS] Add early console for Cobalt.
