      MIPS: mm: Fix duplicate "const" on insn_table_MM · ccf85c74
      James Hogan authored
      Fix the following gcc 7.x build error on microMIPS builds:
      
      arch/mips/mm/uasm-micromips.c:43:26: error: duplicate ‘const’ declaration specifier [-Werror=duplicate-decl-specifier]
       static const struct insn const insn_table_MM[insn_invalid] = {
                                ^~~~~
      
      The same issue has already been fixed in uasm-mips by commit
      00e06297
      
       ("MIPS: mm: remove duplicate "const" qualifier on
      insn_table").

      MIPS: CM: Drop WARN_ON(vp != 0) · c04de7b1
      James Hogan authored
      Since commit 68923cdc ("MIPS: CM: Add cluster & block args to
      mips_cm_lock_other()"), mips_smp_send_ipi_mask() has used
      mips_cm_lock_other_cpu() with each CPU number, rather than
      mips_cm_lock_other() with the first VPE in each core. Prior to r6,
      multicore multithreaded systems such as dual-core dual-thread
      interAptivs with CPU Idle enabled (e.g. MIPS Creator Ci40) results in
      mips_cm_lock_other() repeatedly hitting WARN_ON(vp != 0).
      
      There doesn't appear to be anything fundamentally wrong about passing a
      non-zero VP/VPE number, even if it is a core's region that is locked
      into the other region before r6, so remove that particular WARN_ON().
      
      Fixes: 68923cdc

      MIPS: Fix CPS SMP NS16550 UART defaults · 7e5e371e
      James Hogan authored
      The MIPS_CPS_NS16550_BASE and MIPS_CPS_NS16550_SHIFT options have no
      defaults for non-Malta platforms which select SYS_SUPPORTS_MIPS_CPS
      (i.e. the pistachio and generic platforms). This is problematic for
      automated allyesconfig and allmodconfig builds based on these platforms,
      since make silentoldconfig tries to ask the user for values, and
      especially since v4.15 where the default platform was switched to
      generic.
      
      Default these options to 0 and arrange for MIPS_CPS_NS16550 to be no
      when using that default base address, so that the option only has an
      effect when the default is provided (i.e. Malta) or when a value is
      provided by the user.

      MIPS: BCM47XX Avoid compile error with MIPS allnoconfig · dfe00495
      Matt Redfearn authored
      
      
      Currently MIPS allnoconfig with CONFIG_BCM47XX=y fails to compile due to
      neither BCM47XX_BCMA nor BCM47XX_SSB being selected. This leads the
      enumeration in arch/mips/include/asm/mach-bcm47xx/bcm47xx.h to be empty,
      and compilation fails:
      
      In file included from arch/mips/bcm47xx/irq.c:32:0:
      ./arch/mips/include/asm/mach-bcm47xx/bcm47xx.h:34:1: error: expected
      identifier before '}' token
       };
       ^
      make[2]: *** [scripts/Makefile.build:314: arch/mips/bcm47xx/irq.o] Error 1
      
      Fix this by ensuring that BCM47XX_SSB is selected if BCM47XX_BCMA is
      not. This allows us to select either system or both, but not neither.

      MIPS: AR7: ensure the port type's FCR value is used · 0a5191ef
      Jonas Gorski authored
      Since commit aef9a7bd ("serial/uart/8250: Add tunable RX interrupt
      trigger I/F of FIFO buffers"), the port's default FCR value isn't used
      in serial8250_do_set_termios anymore, but copied over once in
      serial8250_config_port and then modified as needed.
      
      Unfortunately, serial8250_config_port will never be called if the port
      is shared between kernel and userspace, and the port's flag doesn't have
      UPF_BOOT_AUTOCONF, which would trigger a serial8250_config_port as well.
      
      This causes garbled output from userspace:
      
      [    5.220000] random: procd urandom read with 49 bits of entropy available
      ers
         [kee
      
      Fix this by forcing it to be configured on boot, resulting in the
      expected output:
      
      [    5.250000] random: procd urandom read with 50 bits of entropy available
      Press the [f] key and hit [enter] to enter failsafe mode
      Press the [1], [2], [3] or [4] key and hit [enter] to select the debug level
