Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus
Pull MIPS update from Ralf Baechle: "Cleanups and fixes for breakage that occured earlier during this merge phase. Also a few patches that didn't make the first pull request. Of those is the Alchemy work that merges code for many of the SOCs and evaluation boards thus among other code shrinkage, reduces the number of MIPS defconfigs by 5." * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: (22 commits) MIPS: SNI: Switch RM400 serial to SCCNXP driver MIPS: Remove unused empty_bad_pmd_table[] declaration. MIPS: MT: Remove kspd. MIPS: Malta: Fix section mismatch. MIPS: asm-offset.c: Delete unused irq_cpustat_t struct offsets. MIPS: Alchemy: Merge PB1100/1500 support into DB1000 code. MIPS: Alchemy: merge PB1550 support into DB1550 code MIPS: Alchemy: Single kernel for DB1200/1300/1550 MIPS: Optimize TLB refill for RI/XI configurations. MIPS: proc: Cleanup printing of ASEs. MIPS: Hardwire detection of DSP ASE Rev 2 for systems, as required. MIPS: Add detection of DSP ASE Revision 2. MIPS: Optimize pgd_init and pmd_init MIPS: perf: Add perf functionality for BMIPS5000 MIPS: perf: Split the Kconfig option CONFIG_MIPS_MT_SMP MIPS: perf: Remove unnecessary #ifdef MIPS: perf: Add cpu feature bit for PCI (performance counter interrupt) MIPS: perf: Change the "mips_perf_event" table unsupported indicator. MIPS: Align swapper_pg_dir to 64K for better TLB Refill code. vmlinux.lds.h: Allow architectures to add sections to the front of .bss ...
