Merge branch 'upstream' of git://ftp.linux-mips.org/pub/scm/upstream-linus
* 'upstream' of git://ftp.linux-mips.org/pub/scm/upstream-linus: (36 commits) MIPS: Calculate proper ebase value for 64-bit kernels MIPS: Alchemy: DB1200: Remove custom wait implementation MIPS: Big Sur: Make defconfig more useful. MIPS: Fix __vmalloc() etc. on MIPS for non-GPL modules MIPS: Sibyte: Fix M3 TLB exception handler workaround. MIPS: BCM63xx: Fix build failure in board_bcm963xx.c MIPS: uasm: Add OR instruction. MIPS: Sibyte: Apply M3 workaround only on affected chip types and versions. MIPS: BCM63xx: Initialize gpio_out_low & out_high to current value at boot. MIPS: BCM63xx: Register SSB SPROM fallback in board's first stage callback MIPS: BCM63xx: Fix typo in cpu-feature-overrides file. MIPS: BCM63xx: Add support for second uart. MIPS: BCM63xx: Fix double gpio registration. MIPS: BCM63xx: Add DWVS0 board MIPS: BCM63xx: Add the RTA1025W-16 BCM6348-based board to suppported boards. MIPS: BCM63xx: Fix BCM6338 and BCM6345 gpio count MIPS: libgcc.h: Checkpatch cleanup MIPS: Loongson-2F: Flush the branch target history in BTB and RAS MIPS: Move signal trampolines off of the stack. MIPS: Preliminary VDSO ...
