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. Signed-off-by:

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!

Commit abe77f90 (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. Signed-off-by:

Only an interrupt can wake the core from 'wait', enable interrupts locally before executing 'wait'. [ralf@linux-mips.org: This leave the race between an interrupt that's setting TIF_NEED_RESCHEd and entering the WAIT status. but at least it's going to bring Alchemy back from the dead, so I'm going to apply this patch.] Signed-off-by:

Pull timer fixes from Thomas Gleixner: - Trivial: unused variable removal - Posix-timers: Add the clock ID to the new proc interface to make it useful. The interface is new and should be functional when we reach the final 3.10 release. - Cure a false positive warning in the tick code introduced by the overhaul in 3.10 - Fix for a persistent clock detection regression introduced in this cycle * 'timers-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: timekeeping: Correct run-time detection of persistent_clock. ntp: Remove unused variable flags in __hardpps posix-timers: Show clock ID in proc file tick: Cure broadcast false positive pending bit warning

The irqdomain core will report a log message for any attempted map call that fails unless the error code is -EPERM. This patch changes the Versatile irq controller drivers to use -EPERM because it is normal for a subset of the IRQ inputs to be marked as reserved on the various Versatile platforms.

The first_irq needs to be zero to get a linear domain and that comes with special semantics. We want to simplify this going forward but some documentation never hurts. Signed-off-by:
