* arm64: Replace ZONE_DMA32 with ZONE_DMACatalin Marinas2014-02-27
| | | | | | | | On arm64 we do not have two DMA zones, so it does not make sense to implement ZONE_DMA32. This patch changes ZONE_DMA32 with ZONE_DMA, the latter covering 32-bit dma address space to honour GFP_DMA allocations. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
* arm64: vdso: clean up vdso_pagelist initializationNathan Lynch2014-02-26
| | | | | | | | | | | | | | | | | | | Remove some unnecessary bits that were apparently carried over from another architecture's implementation: - No need to get_page() the vdso text/data - these are part of the kernel image. - No need for ClearPageReserved on the vdso text. - No need to vmap the first text page to check the ELF header - this can be done through &vdso_start. Also some minor cleanup: - Use kcalloc for vdso_pagelist array allocation. - Don't print on allocation failure, slab/slub will do that for us.

* arm64: Fix the soft_restart routineGeoff Levand2014-02-26
| | | | | | | | | | | | Change the soft_restart() routine to call cpu_reset() at its identity mapped physical address. The cpu_reset() routine must be called at its identity mapped physical address so that when the MMU is turned off the instruction pointer will be at the correct location in physical memory.

* arm64: Extend the idmap to the whole kernel imageCatalin Marinas2014-02-26
| | | | | | | | | | | | This patch changes the idmap page table creation during boot to cover the whole kernel image, allowing functions like cpu_reset() to be safely called with the physical address. This patch also simplifies the create_block_map asm macro to no longer take an idmap argument and always use the phys/virt/end parameters. For the idmap case, phys == virt.

* arm64: Convert asm/tlb.h to generic mmu_gatherCatalin Marinas2014-02-26
| | | | | | | | | | | | | | | | | | Over the past couple of years, the generic mmu_gather gained range tracking - 597e1c3580b7 (mm/mmu_gather: enable tlb flush range in generic mmu_gather), 2b047252d087 (Fix TLB gather virtual address range invalidation corner cases) - and tlb_fast_mode() has been removed - 29eb77825cc7 (arch, mm: Remove tlb_fast_mode()). The new mmu_gather structure is now suitable for arm64 and this patch converts the arch asm/tlb.h to the generic code. One functional difference is the shift_arg_pages() case where previously the code was flushing the full mm (no tlb_start_vma call) but now it flushes the range given to tlb_gather_mmu() (possibly slightly more efficient previously).

* arm64: enable processor debug state for secondary cpusVijaya Kumar K2014-02-26
| | | | | | | | | | | | processor debug state PSTATE.D is unmasked in smp call clear_os_lock for secondary cpus. So debug state is still masked in normal kernel context. With this patch, unmask debug state on secondary boot for the cpus in normal kernel context. Now kgdb tests passed with multicore.

* KGDB: make kgdb_breakpoint() as noinlineVijaya Kumar K2014-02-26
| | | | | | | | | | | | | | | | | | | | | | The function kgdb_breakpoint() sets up break point at compile time by calling arch_kgdb_breakpoint(); Though this call is surrounded by wmb() barrier, the compile can still re-order the break point, because this scheduling barrier is not a code motion barrier in gcc. Making kgdb_breakpoint() as noinline solves this problem of code reording around break point instruction and also avoids problem of being called as inline function from other places More details about discussion on this can be found here http://comments.gmane.org/gmane.linux.ports.arm.kernel/269732 Signed-off-by: Vijaya Kumar K <Vijaya.Kumar@caviumnetworks.com> Acked-by: Will Deacon <will.deacon@arm.com> Acked-by: Jason Wessel <jason.wessel@windriver.com> Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>

| | |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recent changes to the pwm-backlight driver have made the power supply mandatory. There is code in the regulator core to deal with situations where no regulator is specified and provide a dummy, but that works on DT-based boards only. The situation can be remedied by adding a dummy regulator during board initialization.

What the bug is: There is a problem caused by an invalid calculation of n_voltages in the driver. This n_voltages value has the potential to be different for each regulator. The value for linear_min_sel is set as DA9063_V##regl_name# which can be different depending upon the regulator. This is chosen according to the following definitions in the DA9063 registers.h file: DA9063_VLDO1_BIAS 0 DA9063_VLDO2_BIAS 0 DA9063_VLDO3_BIAS 0 DA9063_VLDO4_BIAS 0 DA9063_VLDO5_BIAS 2 DA9063_VLDO6_BIAS 2 DA9063_VLDO7_BIAS 2 DA9063_VLDO8_BIAS 2 DA9063_VLDO9_BIAS 3 DA9063_VLDO10_BIAS 2 DA9063_VLDO11_BIAS 2 The calculation for n_voltages is valid for LDOs whose BIAS value is zero but this is not correct for those LDOs which have a non-zero value. What the fix is: In order to take into account the non-zero linear_min_sel value which is set for the regulators LDO5, LDO6, LDO7, LDO8, LDO9, LDO10 and LDO11, the calculation for n_voltages should take into account the missing term defined by DA9063_V##regl_name#. This will in turn allow the core constraints calculation to set the maximum voltage limits correctly and therefore allow users to apply the maximum expected voltage to all of the LDOs.
