Merge tag 'mips_5.10' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux
Pull MIPS updates from Thomas Bogendoerfer: - removed support for PNX833x alias NXT_STB22x - included Ingenic SoC support into generic MIPS kernels - added support for new Ingenic SoCs - converted workaround selection to use Kconfig - replaced old boot mem functions by memblock_* - enabled COP2 usage in kernel for Loongson64 to make use of 16byte load/stores possible - cleanups and fixes * tag 'mips_5.10' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux: (92 commits) MIPS: DEC: Restore bootmem reservation for firmware working memory area MIPS: dec: fix section mismatch bcm963xx_tag.h: fix duplicated word mips: ralink: enable zboot support MIPS: ingenic: Remove CPU_SUPPORTS_HUGEPAGES MIPS: cpu-probe: remove MIPS_CPU_BP_GHIST option bit MIPS: cpu-probe: introduce exclusive R3k CPU probe MIPS: cpu-probe: move fpu probing/handling into its own file MIPS: replace add_memory_region with memblock MIPS: Loongson64: Clean up numa.c MIPS: Loongson64: Select SMP in Kconfig to avoid build error mips: octeon: Add Ubiquiti E200 and E220 boards MIPS: SGI-IP28: disable use of ll/sc in kernel MIPS: tx49xx: move tx4939_add_memory_regions into only user MIPS: pgtable: Remove used PAGE_USERIO define MIPS: alchemy: Share prom_init implementation MIPS: alchemy: Fix build breakage, if TOUCHSCREEN_WM97XX is disabled MIPS: process: include exec.h header in process.c MIPS: process: Add prototype for function arch_dup_task_struct MIPS: idle: Add prototype for function check_wait ...
