2013-07-23ARM: pxa: propagate errors from regulator_enable() to pxamciArnd Bergmann
The em_x270_mci_setpower() and em_x270_usb_hub_init() functions call regulator_enable(), which may return an error that must be checked. This changes the em_x270_usb_hub_init() function to bail out if it fails, and changes the pxamci_platform_data->setpower callback so that the a failed em_x270_mci_setpower call can be propagated by the pxamci driver into the mmc core.

2013-07-23arm64: virt: ensure visibility of __boot_cpu_modeMark Rutland
Secondary CPUs write to __boot_cpu_mode with caches disabled, and thus a cached value of __boot_cpu_mode may be incoherent with that in memory. This could lead to a failure to detect mismatched boot modes. This patch adds flushing to ensure that writes by secondaries to __boot_cpu_mode are made visible before we test against it.

Commit 8ef6e6201b26cb9fde79c1baa08145af6aca2815 (ARM: footbridge: use fixed PCI i/o mapping) broke booting on my netwinder. Before that, everything boots fine. Since then, it crashes on boot.

Russell points out it's because of overlapping PCI mappings that was added with the aforementioned commit. Rob thought the code would re-use the static mapping, but that turns out to not be the case and instead hits the BUG further down.

2013-07-19MIPS: Octeon: Fix DT pruning bug with pip portsFaidon Liambotis
During the pruning of the device tree octeon_fdt_pip_iface() is called for each PIP interface and every port up to the port count is removed from the device tree. However, the count was set to the return value of cvmx_helper_interface_enumerate() which doesn't actually return the count but just returns zero on success. This effectively removed *all* ports from the tree. Use cvmx_helper_ports_on_interface() instead to fix this. This successfully restores the 3 ports of my ERLite-3 and fixes the "kernel assigns random MAC addresses" issue.
