2013-06-25MIPS: Sibyte: Platform: Add load address for CONFIG_SIBYTE_LITTLESURMarkos Chandras
Fixes the following build problem: mips-linux-gnu-ld:arch/mips/kernel/vmlinux.lds:253: syntax error because VMLINUX_LOAD_ADDRESS was an empty string for that platform so the vmlinux.lds.S created an invalid section entry on line 50.

2013-06-21WATCHDOG: sb_wdog: Fix 32 bit build failureRalf Baechle
Fixes the following linking problem: drivers/watchdog/sb_wdog.c:211: undefined reference to `__udivdi3' This results from reading a 64 bit register, then dividing the value by 1000000. For 32 bit kernels gcc will use the helper function __udivdi3 from libgcc which the kernel intentionally doesn't provide. In the read registerbits 23..63 are always zero and only bits 0..22 are signficant. So a simple cast to truncate the read value to 32 bits fixes the issue.

2013-06-21MIPS: Fix execution hazard during watchpoint register probePaul Burton
Writing a value to a WatchLo* register creates an execution hazard, so if its value is then read before that hazard is cleared then said value may be invalid. The mips_probe_watch_registers function must therefore clear the execution hazard between setting the match bits in a WatchLo* register & reading the register back in order to check which are set. This fixes intermittent incorrect watchpoint register probing on some MIPS cores such as interAptiv & proAptiv.

2013-06-21MIPS: Loongson: Fix random early boot hangAaro Koskinen
Some Loongson boards (e.g. Lemote FuLoong mini-PC) use ISA/southbridge device (CS5536 general purpose timer) for the timer interrupt. It starts running early and is already enabled during the PCI configuration, during which there is a small window in pci_read_base() when the register access is temporarily disabled. If the timer interrupts at this point, the system will hang. Fix this by adding a fixup that keeps the register access always enabled. The hang the patch fixes usually looks like this: [ 0.844000] pci 0000:00:0e.0: [1022:2090] type 00 class 0x060100 [ 0.848000] pci 0000:00:0e.0: reg 10: [io 0xb410-0xb417] [ 0.852000] pci 0000:00:0e.0: reg 14: [io 0xb000-0xb0ff] [ 0.856000] pci 0000:00:0e.0: reg 18: [io 0xb380-0xb3bf] [ 28.140000] BUG: soft lockup - CPU#0 stuck for 23s!

2013-06-21MIPS: Octeon: Don't clobber bootloader data structures.David Daney
Commit abe77f90dc (MIPS: Octeon: Add kexec and kdump support) added a bootmem region for the kernel image itself. The problem is that this is rounded up to a 0x100000 boundary, which is memory that may not be owned by the kernel. Depending on the kernel's configuration based size, this 'extra' memory may contain data passed from the bootloader to the kernel itself, which if clobbered makes the kernel crash in various ways. The fix: Quit rounding the size up, so that we only use memory assigned to the kernel.
