ARM: 8640/1: Add support for CONFIG_DEBUG_VIRTUAL
x86 has an option: CONFIG_DEBUG_VIRTUAL to do additional checks on virt_to_phys calls. The goal is to catch users who are calling virt_to_phys on non-linear addresses immediately. This includes caller using __virt_to_phys() on image addresses instead of __pa_symbol(). This is a generally useful debug feature to spot bad code (particulary in drivers).

arch: add ARCH_HAS_SET_MEMORY config
Currently, there's no good way to test for the presence of set_memory_ro/rw/x/nx() helpers implemented by archs such as x86, arm, arm64 and s390. There's DEBUG_SET_MODULE_RONX and DEBUG_RODATA, however both don't really reflect that: set_memory_*() are also available even when DEBUG_SET_MODULE_RONX is turned off, and DEBUG_RODATA is set by parisc, but doesn't implement above functions. Thus, add ARCH_HAS_SET_MEMORY that is selected by mentioned archs, where generic code can test against this. This also allows later on to move DEBUG_SET_MODULE_RONX out of the arch specific Kconfig to define it only once depending on ARCH_HAS_SET_MEMORY.

ARM: Drop fixed 200 Hz timer requirement from Samsung platforms
All Samsung platforms, including the Exynos, are selecting HZ_FIXED with
200 Hz. Unfortunately in case of multiplatform image this affects also
other platforms when Exynos is enabled.
This looks like an very old legacy code, dating back to initial
upstreaming of S3C24xx. Probably it was required for s3c24xx timer
driver, which was removed in commit

ARM: SoC cleanups for v4.9
The cleanups for v4.9 are a little larger that usual, but thankfully
that is almost exclusively due to removing a significant number of
files that have become obsolete after the still ongoing conversion
of old board files to devicetree.
- for mach-omap2, which is still the largest platform in arch/arm/,
the conversion to DT is finally complete after the Nokia N900 is
now fully supported there, along with the omap3 LDP, and we can
remove those two board files.
If no regressions are found, another large cleanup for the platform
will happen as a follow-up, removing dead code and restructuring
the platform based on being DT-only.
- In mach-imx, similar work is ongoing, but has not come that far.
This time, we remove the obsolete board file for the i.MX1
generation, which like i.MX25, i.MX5, i.MX6, and i.MX7 is now DT-only.
The remaining board files are for i.MX2 and i.MX3 machines
based on old ARM926 or ARM1136 cores that should work with DT
in principle.
- realview has just been converted from board files to DT, and a lot
of code gets removed in the process. This is the last
ARM/Keil/Versatile derived platform that was still using board
files, the other ones being integrator, versatile and vexpress.
We can probably merge the remaining code into a single directory
in the near future.
- clps711x had completed the conversion in v4.8, but we accidentally
left the files in place that should have been deleted then.
Conflicts: two files deleted here have been modified upstream,
the changes can be discarded.

atomic64: no need for CONFIG_ARCH_HAS_ATOMIC64_DEC_IF_POSITIVE
This came to light when implementing native 64-bit atomics for ARCv2. The atomic64 self-test code uses CONFIG_ARCH_HAS_ATOMIC64_DEC_IF_POSITIVE to check whether atomic64_dec_if_positive() is available. It seems it was needed when not every arch defined it. However as of current code the Kconfig option seems needless - for CONFIG_GENERIC_ATOMIC64 it is auto-enabled in lib/Kconfig and a generic definition of API is present lib/atomic64.c - arches with native 64-bit atomics select it in arch/*/Kconfig and define the API in their headers So I see no point in keeping the Kconfig option Compile tested for: - blackfin (CONFIG_GENERIC_ATOMIC64) - x86 (!CONFIG_GENERIC_ATOMIC64) - ia64 Link: http://lkml.kernel.org/r/1473703083-8625-3-git-send-email-vgupta@synopsys.com Signed-off-by: Vineet Gupta <vgupta@synopsys.com> Cc: Richard Henderson <rth@twiddle.net> Cc: Ivan Kokshaysky <ink@jurassic.park.msu.ru> Cc: Matt Turner <mattst88@gmail.com> Cc: Russell King <linux@armlinux.org.uk> Cc: Catalin Marinas <catalin.marinas@arm.com> Cc: Will Deacon <will.deacon@arm.com> Cc: Ralf Baechle <ralf@linux-mips.org> Cc: "James E.J.

Merge branch 'irq-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull irq updates from Thomas Gleixner:
"The irq departement proudly presents:
- A rework of the core infrastructure to optimally spread interrupt
for multiqueue devices. The first version was a bit naive and
failed to take thread siblings and other details into account.
Developed in cooperation with Christoph and Keith.
- Proper delegation of softirqs to ksoftirqd, so if ksoftirqd is
active then no further softirq processsing on interrupt return
happens. Otherwise we try to delegate and still run another batch
of network packets in the irq return path, which then tries to
delegate to ksoftirqd .....
- A proper machine parseable sysfs based alternative for
/proc/interrupts.
- ACPI support for the GICV3-ITS and ARM interrupt remapping
- Two new irq chips from the ARM SoC zoo: STM32-EXTI and MVEBU-PIC
- A new irq chip for the JCore (SuperH)
- The usual pile of small fixlets in core and irqchip drivers"

ARM: select PCI_DOMAINS config from ARCH_MULTIPLATFORM
PCI_DOMAINS config should be selected for any SoCs having more than a single PCIe controller. Without PCI_DOMAINS config, only one PCIe controller gets registered. Select PCI_DOMAINS in ARCH_MULTIPLATFORM if PCI is selected, since it doesn't harm even if a platform has a single PCIe port. Also remove PCI_DOMAINS being selected from other platform specific configs.

ARM: realview: imply device tree boot
This reduces the Kconfig for the RealView by assuming we are always booting from the device tree, and removing all the uses of CONFIG_REALVIEW_DT and replacing with CONFIG_ARCH_REALVIEW. Further: - Drop REALVIEW_HIGH_PHYS_OFFSET: we don't use this with device tree. - Drop the REALVIEW_EB_ARM11MP_REVB option: we now handle this by simply using another device tree. - Drop the PB1176 secure flash option: this is defined in the PB1176 device tree but marked as "disabled", so users who want to use it can simply enable it in the device tree and go hacking around.

ARM: 8560/1: errata: Workaround errata A12 825619 / A17 852421
The workaround for both errata is to set bit 24 in the diagnostic register. There are no known end-user bugs solved by fixing this errata, but the fix is trivial and it seems sane to apply it.

This erratum has a very simple workaround (set a bit in a register), so let's apply it. Apparently the workaround's downside is a very slight power impact. Note that applying this errata fixes deadlocks that are easy to reproduce with real world applications.

ARM: 8558/1: errata: Workaround errata A12 818325/852422 A17 852423
There are several similar errata on Cortex A12 and A17 that all have the same workaround: setting bit[12] of the Feature Register. Technically the list of errata are: - A12 818325: Execution of an UNPREDICTABLE STR or STM instruction might deadlock. Fixed in r0p1. - A12 852422: Execution of a sequence of instructions might lead to either a data corruption or a CPU deadlock. Not fixed in any A12s yet. - A17 852423: Execution of a sequence of instructions might lead to either a data corruption or a CPU deadlock. Not fixed in any A17s yet. Since A12 got renamed to A17 it seems likely that there won't be any future Cortex-A12 cores, so we'll enable for all Cortex-A12. For Cortex-A17 I believe that all known revisions are affected and that all knows revisions means <= r1p2. Presumably if a new A17 was released it would have this problem fixed. Note that in <https://patchwork.kernel.org/patch/4735341/> folks previously expressed opposition to this change because: A) It was thought to only apply to r0p0 and there were no known r0p0 boards supported in mainline. B) It was argued that such a workaround beloned in firmware. Now that this same fix solves other errata on real boards (like rk3288) point A) is addressed. Point B) is impossible to address on boards like rk3288. On rk3288 the firmware doesn't stay resident in RAM and isn't involved at all in the suspend/resume process nor in the SMP bringup process. That means that the most the firmware could do would be to set the bit on "core 0" and this bit would be lost at suspend/resume time. It is true that we could write a "generic" solution that saved the boot-time "core 0" value of this register and applied it at SMP bringup / resume time. However, since this register (described as the "Feature Register" in errata) appears to be undocumented (as far as I can tell) and is only modified for these errata, that "generic" solution seems questionably cleaner. The generic solution also won't fix existing users that haven't happened to do a FW update. Note that in ARM64 presumably PSCI will be universal and fixes like this will end up in ATF. Hopefully we are nearing the end of this style of errata workaround.

PCI/MSI: irqchip: Fix PCI_MSI dependencies
The PCI_MSI symbol is used inconsistently throughout the tree, with some
drivers using 'select' and others using 'depends on', or using conditional
selects. This keeps causing problems; the latest one is a result of
ARCH_ALPINE using a 'select' statement to enable its platform-specific MSI
driver without enabling MSI:
warning: (ARCH_ALPINE) selects ALPINE_MSI which has unmet direct dependencies (PCI && PCI_MSI)
drivers/irqchip/irq-alpine-msi.c:104:15: error: variable 'alpine_msix_domain_info' has initializer but incomplete type
static struct msi_domain_info alpine_msix_domain_info = {
^~~~~~~~~~~~~~~
drivers/irqchip/irq-alpine-msi.c:105:2: error: unknown field 'flags' specified in initializer
.flags = MSI_FLAG_USE_DEF_DOM_OPS | MSI_FLAG_USE_DEF_CHIP_OPS |

.flags = MSI_FLAG_USE_DEF_DOM_OPS | MSI_FLAG_USE_DEF_CHIP_OPS |
^~~~~~~~~~~~~~~~~~~~~~~~
There is little reason to enable PCI support for a platform that uses MSI
but then leave MSI disabled at compile time.
Select PCI_MSI from irqchips that implement MSI, and make PCI host bridges
that use MSI on ARM depend on PCI_MSI_IRQ_DOMAIN.
For all three architectures that support PCI_MSI_IRQ_DOMAIN (ARM, ARM64,
X86), enable it by default whenever MSI is enabled.

GCC plugin infrastructure
This patch allows to build the whole kernel with GCC plugins. It was ported from
grsecurity/PaX. The infrastructure supports building out-of-tree modules and
building in a separate directory. Cross-compilation is supported too.
Currently the x86, arm, arm64 and uml architectures enable plugins.
The directory of the gcc plugins is scripts/gcc-plugins. You can use a file or a directory
there. The plugins compile with these options:
* -fno-rtti: gcc is compiled with this option so the plugins must use it too
* -fno-exceptions: this is inherited from gcc too
* -fasynchronous-unwind-tables: this is inherited from gcc too
* -ggdb: it is useful for debugging a plugin (better backtrace on internal
errors)
* -Wno-narrowing: to suppress warnings from gcc headers (ipa-utils.h)
* -Wno-unused-variable: to suppress warnings from gcc headers (gcc_version
variable, plugin-version.h)
The infrastructure introduces a new Makefile target called gcc-plugins. It
supports all gcc versions from 4.5 to 6.0. The scripts/gcc-plugin.sh script
chooses the proper host compiler (gcc-4.7 can be built by either gcc or g++).
This script also checks the availability of the included headers in
scripts/gcc-plugins/gcc-common.h.
The gcc-common.h header contains frequently included headers for GCC plugins
and it has a compatibility layer for the supported gcc versions.
The gcc-generate-*-pass.h headers automatically generate the registration
structures for GIMPLE, SIMPLE_IPA, IPA and RTL passes.
Note that 'make clean' keeps the *.so files (only the distclean or mrproper
targets clean all) because they are needed for out-of-tree modules.
Based on work created by the PaX Team.

ARM: do away with ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB
This replaces: - "select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB" as this can now be selected directly. - "select ARCH_WANT_OPTIONAL_GPIOLIB" with no dependency: GPIOLIB is now selectable by everyone, so we need not declare our intent to select it. When ordering the symbols the following rationale was used: if the selects were in alphabetical order, I moved select GPIOLIB to be in alphabetical order, but if the selects were not maintained in alphabetical order, I just replaced "select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB".

ARM: SoC platform updates for v4.7
We get support for three new 32-bit SoC platforms this time. The amount of changes in arch/arm for any of them is miniscule, as all the interesting code is in device driver subsystems (irqchip, clk, pinctrl, ...) these days. I'm listing them here, as the addition of the Kconfig statement is the main relevant milestone for a new platform. In each case, some drivers are are shared with existing platforms, while other drivers are added for v4.7 as well, or come in a later release. - The Aspeed platform is probably the most interesting one, this is what most whitebox servers use as their baseboard management controller. We get support for the very common ast2400 and ast2500 SoCs. The OpenBMC project focuses on this chip, and the LWN article about their ELC 2016 presentation at https://lwn.net/Articles/683320/ triggered the submission, but the code comes from IBM's OpenPOWER team rather than the team at Facebook. There are still a lot more drivers that need to get added over time, and I hope both teams can work together on that. - OXNAS is an old platform for Network Attached Storage devices from Oxford Semiconductor. There are models with ARM10 (!) and ARM11MPCore cores, but for now, we only support the original ARM9 based versions. The product lineup was subsequently part of PLX, Avago and now the new Broadcom Ltd. https://wiki.openwrt.org/doc/hardware/soc/soc.oxnas has some more information. - V2M-MPS2 is a prototyping platform from ARM for their Cortex-M cores and is related to the existing Realview / Versatile Express lineup, but without MMU. We now support various NOMMU platforms, so adding a new one is fairly straightforward. http://infocenter.arm.com/help/topic/com.arm.doc.100112_0100_03_en/ has detailed information about the platform. Other noteworthy updates: - Work on LPC32xx has resumed, and Vladimir Zapolskiy and Sylvain Lemieux are now maintaining the platform. This is an older ARM9 based platform from NXP (not Freescale), but it remains in use in embedded markets. - Kevin Hilman is now co-maintaining the Amlogic Meson platform for both 32-bit and 64-bit ARM, and started contributing some patches. - As is often the case, work on the OMAP platforms makes up the bulk of the actual SoC code changes in arch/arm, but there isn't a lot of that either. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIVAwUAVzuXX2CrR//JCVInAQLTghAA0f+2V2wC6HVBfDhT1YmhbAkPF1KzgLbB h30fN6BtIe9mE3kR69uWgwPSzn4hTKEQXoC9m6S+XClTn6MKPrbCEYDZl4ZwIER8 XDamxJV+6oTG+GKtKpHFkC4WPJkLthEuD34gr2xU8DFrU+y2Y5QNXi5wvSsBp8WS 6C/70HQEy35uSyOjbjVlPi0/UKoelVw9dCO7HZBOb9lTd88hC4Gx90KFwpq6Ievf L20VNgOESC2y6kRbuLNbhQVsbT2Ijyz9NccVM5owFEbHkXDxJ0vQVzrNM999DVjb CC2v0NZMLPNJQn2RvC172QBOsOERxIRkZdJHcifydl7i2QNpr8+/YSnS7OSx3dA/ 3ZmTLejaiGUXdTGEI9dHy77s+adwTzGsH+INKotQG8qwUXzCLuUWN3GGK+Qof5Rk jbsGAoZ7GQz1/7NdEOcGW6pxD4mllk3McKMzNlMmddRDUPhSUg3WXu0c1AWGzfA1 ulk6fQDaTUjvs7nokuozhguKz8OKrT6S7x/iES5tPbXLhuDqfnUdYiQ+7m2beRb5 L9S9KK95HXnKJAI9WLOELj1vCrfbCGjlwz8YVSrwPtwwzP/wbB1Ni6tmwLrxHbLk SGyJEMnPs3mARIPDwDysyOs+3OUSx04uYW6YTSh8XyKNIxTCflRxr/iM5YyYEMvt lXMrp1sh4hc= =5oFu -----END PGP SIGNATURE----- Merge tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC platform updates from Arnd Bergmann: "We get support for three new 32-bit SoC platforms this time.

irqchip: Add LPC32xx interrupt controller driver
The change adds improved support of NXP LPC32xx MIC, SIC1 and SIC2 interrupt controllers. This is a list of new features in comparison to the legacy driver: * irq types are taken from device tree settings, no more need to hardcode them, * old driver is based on irq_domain_add_legacy, which causes problems with handling MIC hardware interrupt 0 produced by SIC1, * there is one driver for MIC, SIC1 and SIC2, no more need to handle them separately, e.g. have two separate handlers for SIC1 and SIC2, * the driver does not have any dependencies on hardcoded register offsets, * the driver is much simpler for maintenance, * SPARSE_IRQS option is supported. Legacy LPC32xx interrupt controller driver was broken since commit |
