2013-09-18ARM: dts: Fix muxing and regulator for wl12xx on the SDIO bus for blazeTony Lindgren
Commit 76787b3b (ARM: OMAP2+: Remove board-4430sdp.c) removed legacy booting in favor of device tree based booting for 4430sdp. That caused the WLAN to stop working as the related .dts entries fell through the cracks. I don't have the "1283 PG 2.21 connectivity device" on my 4430sdp, but the earlier version of this patch was tested by Luciano Coelho. This version has left out the input logic for MMC CLK line compared to the earlier version as that is not bidirectional, and should be safe to do.

2013-09-18ARM: dts: Fix muxing and regulator for wl12xx on the SDIO bus for pandaboardTony Lindgren
Commit b42b9181 (ARM: OMAP2+: Remove board-omap4panda.c) removed legacy booting in favor of device tree based booting for pandaboard. That caused the WLAN to stop working as the related .dts entries fell through the cracks. The legacy muxing was setting pulls for GPIO 48 and 49, so let's keep that behaviour for now to avoid further regressions for BT and FM. Also input logic was enabled for MMC CLK line, but I've verified that the input logic we don't need enabled for CLK line as it's not bidirectional. Also, we want to use non-removable instead of ti,non-removable as the ti,non-removable also sets no_regulator_off_init which is really not what we want as then wl12xx won't get powered up and down which is needed for resetting it. Note that looks like the WLAN interface fails to come up after a warm reset, but that most likely was also happening with the legacy booting and needs a separate fix.

2013-09-17ARM: tegra: split tegra_pmc_init() in twoStephen Warren
Tegra's board file currently initializes clocks much earlier than those for most other ARM SoCs. The reason is: * The PMC HW block is involved in the path of some interrupts (i.e. it inverts, or not, the IRQ input pin dedicated to the PMIC). * So, that part of the PMC must be initialized early so that the IRQ polarity is correct. * The PMC initialization is currently monolithic, and the PMC has some clock inputs, so the init routine ends up calling of_clk_get_by_name(), and hence clocks must be set up early too. In order to defer clock initialization to the more typical location, split out the portions of tegra_pmc_init() that are truly IRQ-related into a separate tegra_pmc_init_irq(), which can be called from the machine descriptor's .init_irq() function, and defer the rest until the machine descriptor's .init_machine() function. This allows the clock initiliazation to happen from the machine descriptor's .init_time() function, as is typical. Signed-off-by: Stephen Warren <swarren@nvidia.com>

2013-09-17ARM: ux500: disable outer cache debugLinus Walleij
This fixes a multiplatform regression on the Ux500. When compiling the Ux500 platforms in multiplatform configurations both PL310_ERRATA_588369 and PL310_ERRATA_727915 would crash the platform when trying to launch the init process. The Ux500 cannot access the debug registers of the PL310, it will just crash if you try this. So disable this by setting the debug callback to NULL when initializing the l2x0 on this platform.

2013-09-11mm: migrate: check movability of hugepage in unmap_and_move_huge_page()Naoya Horiguchi
Currently hugepage migration works well only for pmd-based hugepages (mainly due to lack of testing,) so we had better not enable migration of other levels of hugepages until we are ready for it. Some users of hugepage migration (mbind, move_pages, and migrate_pages) do page table walk and check pud/pmd_huge() there, so they are safe. But the other users (softoffline and memory hotremove) don't do this, so without this patch they can try to migrate unexpected types of hugepages. To prevent this, we introduce hugepage_migration_support() as an architecture dependent check of whether hugepage are implemented on a pmd basis or not. And on some architecture multiple sizes of hugepages are available, so hugepage_migration_support() also checks hugepage size.

2013-09-09Merge branch 'versatile/fixes' into fixesOlof Johansson
From Peter Maydell: These patches fix a number of issues with the PCI controller code for mach-versatile: (1) The irq mapping matched neither hardware nor QEMU; we correct it to match the hardware, which means it will also work on recent (1.5 or later) QEMU. (2) The code was confused between the PCI I/O window (at 0x43000000) and the first PCI memory window (at 0x44000000), which meant that PCI devices using PCI PIO rather than MMIO didn't work. This is fixed (and some variables/labels are renamed to avoid further confusion in future). (3) The SMAP register offsets were all off-by-four, though by fluke this didn't actually have any ill effects. All these changes have been tested on real hardware (PB926 plus the PCI backplane), as well as on QEMU. I have confirmed that IRQs and PCI PIO and MMIO work OK. PCI bus-master DMA doesn't seem to work on h/w -- as far as I can tell the device is correctly managing to DMA to the right places in memory, but every other 32 bit word is corrupt (at least judging from rtl8139 debug dumps of the frames it's receiving). I'm not sure what's going on here, but since this is disjoint from the irq and I/O issues I don't think that applying the patches that fix those should be stalled on trying to debug DMA problems. (DMA works fine on QEMU, incidentally.) * versatile/fixes: ARM: PCI: versatile: Fix SMAP register offsets ARM: PCI: versatile: Fix PCI I/O ARM: PCI: versatile: Fix map_irq function to match hardware Signed-off-by: Olof Johansson <olof@lixom.net>

When linux is running as dom0, Xen doesn't show the physical cpu but a virtual CPU. On some ARM SOC (for instance the exynos 5250), linux registers callbacks for cpuidle and cpufreq. When these callbacks are called, they will modify directly the physical cpu not the virtual one. It can impact the whole board instead of only dom0.
