2014-11-26arm64: Move some head.text functions to executable sectionLaura Abbott
The head.text section is intended to be run at early bootup before any of the regular kernel mappings have been setup. Parts of head.text may be freed back into the buddy allocator due to TEXT_OFFSET so for security requirements this memory must not be executable. The suspend/resume/hotplug code path requires some of these head.S functions to run however which means they need to be executable. Support these conflicting requirements by moving the few head.text functions that need to be executable to the text section which has the appropriate page table permissions.

2014-11-26arm64: jump labels: NOP out NOP -> NOP replacementMark Rutland
In the arm64 arch_static_branch implementation we place an A64 NOP into the instruction stream and log relevant details to a jump_entry in a __jump_table section. Later this may be replaced with an immediate branch without link to the code for the unlikely case. At init time, the core calls arch_jump_label_transform_static to initialise the NOPs. On x86 this involves inserting the optimal NOP for a given microarchitecture, but on arm64 we only use the architectural NOP, and hence replace each NOP with the exact same NOP. This is somewhat pointless. Additionally, at module load time we don't call jump_label_apply_nops to patch the optimal NOPs in, unlike other architectures, but get away with this because we only use the architectural NOP anyway. A later notifier will patch NOPs with branches as required. Similarly to x86 commit 11570da1c5b1dee1 (x86/jump-label: Do not bother updating NOPs if they are correct), we can avoid patching NOPs with identical NOPs. Given that we only use a single NOP encoding, this means we can NOP-out the body of arch_jump_label_transform_static entirely. As the default __weak arch_jump_label_transform_static implementation performs a patch, we must use an empty function to achieve this.

2014-11-26kvm: fix kvm_is_mmio_pfn() and rename to kvm_is_reserved_pfn()Ard Biesheuvel
This reverts commit 85c8555ff0 ("KVM: check for !is_zero_pfn() in kvm_is_mmio_pfn()") and renames the function to kvm_is_reserved_pfn. The problem being addressed by the patch above was that some ARM code based the memory mapping attributes of a pfn on the return value of kvm_is_mmio_pfn(), whose name indeed suggests that such pfns should be mapped as device memory. However, kvm_is_mmio_pfn() doesn't do quite what it says on the tin, and the existing non-ARM users were already using it in a way which suggests that its name should probably have been 'kvm_is_reserved_pfn' from the beginning, e.g., whether or not to call get_page/put_page on it etc. This means that returning false for the zero page is a mistake and the patch above should be reverted.

2014-11-26arm64: KVM: Handle traps of ICC_SRE_EL1 as RAZ/WIChristoffer Dall
When running on a system with a GICv3, we currenly don't allow the guest to access the system register interface of the GICv3. We do this by clearing the ICC_SRE_EL2.Enable, which causes all guest accesses to ICC_SRE_EL1 to trap to EL2 and causes all guest accesses to other ICC_ registers to cause an undefined exception in the guest. However, we currently don't handle the trap of guest accesses to ICC_SRE_EL1 and will spill out a warning. The trap just needs to handle the access as RAZ/WI, and a guest that tries to prod this register and set ICC_SRE_EL1.SRE=1, must read back the value (which Linux already does) to see if it succeeded, and will thus observe that ICC_SRE_EL1.SRE was not set. Add the simple trap handler in the sorted table of the system registers.

2014-11-26arm64: KVM: fix unmapping with 48-bit VAsMark Rutland
Currently if using a 48-bit VA, tearing down the hyp page tables (which can happen in the absence of a GICH or GICV resource) results in the rather nasty splat below, evidently becasue we access a table that doesn't actually exist. Commit 38f791a4e499792e (arm64: KVM: Implement 48 VA support for KVM EL2 and Stage-2) added a pgd_none check to __create_hyp_mappings to account for the additional level of tables, but didn't add a corresponding check to unmap_range, and this seems to be the source of the problem. This patch adds the missing pgd_none check, ensuring we don't try to access tables that don't exist.

omap_hsmmc supports only one slot per controller, see OMAP_MMC_MAX_SLOTS. This unnecessary indirection leads to confusion in the omap_hsmmc driver. For example the card_detect callback is not installed by platform code but from the driver probe function. So it should be a field of omap_hsmmc_host. But since it is declared under the platform slot while the drivers struct omap_hsmmc_host has no slot abstraction, this looks like a bug, especially when not familiar that this driver only supports 1 slot anyway. Either we should add a slot abstraction to omap_hsmmc_host or remove it from the platform data struct.

2014-11-26ARM: OMAP1/2+: MMC: separate platform data for mmc and mmc hs driverAndreas Fenkart
- omap mmc driver supports multiplexing, omap_mmc_hs doesn't this leads to one of the major confusions in the omap_hsmmc driver - platform data should be read-only for the driver most callbacks are not set by the omap3 platform init code while still required. So they are set from the driver probe function, which is against the paradigm that platform-data should not be modified by the driver typical examples are card_detect, read_only callbacks un-bundling by searching for driver name \"omap_hsmmc in the arch/arm folder. omap_hsmmc_platform_data is not initialized directly, but from omap2_hsmmc_info, which is defined in a separate header file not touched by this patch hwmod includes platform headers to declare features of the platform. All the declared features are prefixed OMAP_HSMMC. There is no need to include platform header from hwmod other except for feature defines Acked-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Andreas Fenkart <afenkart@gmail.com> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
2014-11-26ARM: OMAP2: MMC: include mmc-omap platform header directlyAndreas Fenkart
Only a few files really need that platform header. When later splitting omap_mmc_platform_data into omap_mmc and omap_mmc_hs, those files declaring an hs mmc platform data will have to change the platform include, which is a good sanity check.

2014-11-26arm64: Add FIX_HOLE to permanent fixed addressesLaura Abbott
Every other architecture with permanent fixed addresses has FIX_HOLE as the first entry. This seems to be designed as a debugging aid but there are a couple of side effects of not having FIX_HOLE: - If the first fixed address is 0, fix_to_virt -> virt_to_fix triggers a BUG_ON for the virtual address being equal to FIXADDR_TOP - fix_to_virt may return a value outside of FIXADDR_START and FIXADDR_TOP which may look like a bug to a developer. Match up with other architectures and make everything clearer by adding FIX_HOLE. Signed-off-by: Laura Abbott <lauraa@codeaurora.org> Signed-off-by: Will Deacon <will.deacon@arm.com>

struct bfin_serial_port contains structs circ_buf, timer_list, and work_struct directly (not pointers). This means that these structures have to be defined completely to be inlined in struct bfin_serial_port. So instead of struct declarations, define the structures by including proper headers.

Most of the commits contained here are sparse or coccinelle fixes ranging from missing 'static' to returning 0 in case of errors. More importantly, we have the removal the now unnecessary 'driver' argument to ->udc_stop(). DWC2 learned about Dual-Role builds. Users of this IP can now have a single driver built for host and device roles. DWC3 got support for two new HW platforms: Exynos7 and AMD. The Broadcom USB 3.0 Device Controller IP is now supported and so is PLX USB338x, which means DWC3 has lost is badge as the only USB 3.0 peripheral IP supported on Linux. Thanks for Tony Lindgren's work, we can now have a distro-like kernel where all MUSB glue layers can be built into the same kernel (statically or dynamically linked) and it'll work in PIO (DMA will come probably on v3.20).

While we currently expect self-hosted debug support to be identical across CPUs, we don't currently sanity check this. This patch adds logging of the ID_AA64DFR{0,1}_EL1 values and associated sanity checking code. It's not clear to me whether we need to check PMUVer, TraceVer, and DebugVer, as we don't currently rely on these fields at all.

2014-11-25arm64: sanity checks: add missing newline to printMark Rutland
A missing newline in the WARN_TAINT_ONCE string results in ugly and somewhat difficult to read output in the case of a sanity check failure, as the next print does not appear on a new line: Unsupported CPU feature variation.Modules linked in: This patch adds the missing newline, fixing the output formatting.
