ARM: pxa: fix pxa interrupts handling in DT
The commit "ARM: pxa: arbitrarily set first interrupt number" changed the first pxa interrupt to 16. As a consequence, device-tree builds got broken, because : - pxa_mask_irq() and pxa_unmask_irq() are using IRQ_BIT() - IRQ_BIT(x) calculates the interrupts as : x - PXA_IRQ(0) Before the commit, the first interrupt shift, PXA_IRQ(0) was 0, therefore IRQ_BIT(x) was x. After the change, it is necessary that the same shift of 16 is applied between the virtual interrupt number and the hardware irq number. This situation comes from the common irq_chip shared between legacy platform builds and device-tree builds. Fix the broken interrupts in DT case by adding this shift in the DT case too. As a consequence of the IRQ_BIT() is removed alltogether from interrupts handling, even in the platform data types of platforms : - a legacy irq domain is used - the irq_chip handles hardware interrupts - the virtual to hardware interrupt conversion is fully handled by irq domain mechanics Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr> |

ARM: SoC platform changes
New and updated SoC support. Also included are some cleanups where the
platform maintainers hadn't separated cleanups from new developent in
separate branches.
Some of the larger things worth pointing out:
- A large set of changes from Alexandre Belloni and Nicolas Ferre
preparing at91 platforms for multiplatform and cleaning up quite a
bit in the process.
- Removal of CSR's "Marco" SoC platform that never made it out to the
market. We love seeing these since it means the vendor published
support before product was out, which is exactly what we want!
New platforms this release are:
- Conexant Digicolor (CX92755 SoC)
- Hisilicon HiP01 SoC
- CSR/sirf Atlas7 SoC
- ST STiH418 SoC
- Common code changes for Nvidia Tegra132 (64-bit SoC)
We're seeing more and more platforms having a harder time labelling
changes as cleanups vs new development -- which is a good sign that
we've come quite far on the cleanup effort. So over time we might start
combining the cleanup and new-development branches more.

ARM: kprobes: enable OPTPROBES for ARM 32
This patch introduce kprobeopt for ARM 32. Limitations: - Currently only kernel compiled with ARM ISA is supported. - Offset between probe point and optinsn slot must not larger than 32MiB. Masami Hiramatsu suggests replacing 2 words, it will make things complex. Futher patch can make such optimization. Kprobe opt on ARM is relatively simpler than kprobe opt on x86 because ARM instruction is always 4 bytes aligned and 4 bytes long. This patch replace probed instruction by a 'b', branch to trampoline code and then calls optimized_callback(). optimized_callback() calls opt_pre_handler() to execute kprobe handler. It also emulate/simulate replaced instruction. When unregistering kprobe, the deferred manner of unoptimizer may leave branch instruction before optimizer is called. Different from x86_64, which only copy the probed insn after optprobe_template_end and reexecute them, this patch call singlestep to emulate/simulate the insn directly. Futher patch can optimize this behavior.

ARM/PCI: Move to generic PCI domains
Most if not all ARM PCI host controller device drivers either ignore the domain field in the pci_sys_data structure or just increment it every time a host controller is probed, using it as a domain counter. Therefore, instead of relying on pci_sys_data to stash the domain number in a standard location, ARM pcibios code can be moved to the newly introduced generic PCI domains code, implemented in commits: |

ARM: SoC driver updates for 3.19
These are changes for drivers that are intimately tied to some SoC
and for some reason could not get merged through the respective
subsystem maintainer tree.
The largest single change here this time around is the Tegra
iommu/memory controller driver, which gets updated to the new
iommu DT binding. More drivers like this are likely to follow
for the following merge window, but we should be able to do
those through the iommu maintainer.
Other notable changes are:
* reset controller drivers from the reset maintainer (socfpga, sti, berlin)
* fixes for the keystone navigator driver merged last time
* at91 rtc driver changes related to the at91 cleanups
* ARM perf driver changes from Will Deacon
* updates for the brcmstb_gisb driver

kexec: remove CONFIG_KEXEC dependency on crypto
New system call depends on crypto. As it did not have a separate config option, CONFIG_KEXEC was modified to select CRYPTO and CRYPTO_SHA256. But now previous patch introduced a new config option for new syscall. So CONFIG_KEXEC does not require crypto. Remove that dependency.

kexec: load and relocate purgatory at kernel load time
Load purgatory code in RAM and relocate it based on the location. Relocation code has been inspired by module relocation code and purgatory relocation code in kexec-tools. Also compute the checksums of loaded kexec segments and store them in purgatory. Arch independent code provides this functionality so that arch dependent bootloaders can make use of it. Helper functions are provided to get/set symbol values in purgatory which are used by bootloaders later to set things like stack and entry point of second kernel etc. Signed-off-by: Vivek Goyal <vgoyal@redhat.com> Cc: Borislav Petkov <bp@suse.de> Cc: Michael Kerrisk <mtk.manpages@gmail.com> Cc: Yinghai Lu <yinghai@kernel.org> Cc: Eric Biederman <ebiederm@xmission.com> Cc: H.

ARM: SoC device-tree changes for 3.17
Unlike the board branch, this keeps having large sets of changes for
every release, but that's quite expected and is so far working well.
Most of this is plumbing for various device bindings and new platforms,
but there's also a bit of cleanup and code removal for things that
are moved from platform code to DT contents (some OMAP clock code in
particular).
There's also a pinctrl driver for tegra here (appropriately acked),
that's introduced this way to make it more bisectable.
I'm happy to say that there were no conflicts at all with this branch
this release, which means that changes are flowing through our tree as
expected instead of merged through driver maintainers (or at least not
done with conflicts).
There are several new boards added, and a couple of SoCs. In no particular
order:
* Rockchip RK3288 SoC support, including DTS for a dev board that they
have seeded with some community developers.
* Better support for Hardkernel Exynos4-based ODROID boards.
* CCF conversions (and dtsi contents) for several Renesas platforms.
* Gumstix Pepper (TI AM335x) board support
* TI eval board support for AM437x
* Allwinner A23 SoC, very similar to existing ones which mostly has
resulted in DT changes for support. Also includes support for an Ippo
tablet with the chipset.
* Allwinner A31 Hummingbird board support, not to be confused with the
SolidRun i.MX-based Hummingboard.
* Tegra30 Apalis board support

ARM: SoC platform changes for 3.17
This is the bulk of new SoC enablement and other platform changes for 3.17:
* Samsung S5PV210 has been converted to DT and multiplatform
* Clock drivers and bindings for some of the lower-end i.MX 1/2 platforms
* Kirkwood, one of the popular Marvell platforms, is folded into the
mvebu platform code, removing mach-kirkwood.
* Hwmod data for TI AM43xx and DRA7 platforms.
* More additions of Renesas shmobile platform support
* Removal of plat-samsung contents that can be removed with S5PV210 being
multiplatform/DT-enabled and the other two old platforms being removed.
New platforms (most with only basic support right now):
* Hisilicon X5HD2 settop box chipset is introduced
* Mediatek MT6589 (mobile chipset) is introduced
* Broadcom BCM7xxx settop box chipset is introduced
+ as usual a lot other pieces all over the platform code.

ARM: SoC cleanups for 3.17
This merge window brings a good size of cleanups on various
platforms. Among the bigger ones:
* Removal of Samsung s5pc100 and s5p64xx platforms. Both of these have
lacked active support for quite a while, and after asking around nobody
showed interest in keeping them around. If needed, they could be
resurrected in the future but it's more likely that we would prefer
reintroduction of them as DT and multiplatform-enabled platforms
instead.
* OMAP4 controller code register define diet. They defined a lot of registers
that were never actually used, etc.
* Move of some of the Tegra platform code (PMC, APBIO, fuse, powergate)
to drivers/soc so it can be shared with 64-bit code. This also converts them
over to traditional driver models where possible.
* Removal of legacy gpio-samsung driver, since the last users have been
removed (moved to pinctrl)
Plus a bunch of smaller changes for various platforms that sort of
dissapear in the diffstat for the above. clps711x cleanups, shmobile
header file refactoring/moves for multiplatform friendliness, some misc
cleanups, etc.

Merge tag 'cleanup-for-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC cleanups from Olof Johansson:
"This merge window brings a good size of cleanups on various platforms.
Among the bigger ones:
- Removal of Samsung s5pc100 and s5p64xx platforms. Both of these
have lacked active support for quite a while, and after asking
around nobody showed interest in keeping them around. If needed,
they could be resurrected in the future but it's more likely that
we would prefer reintroduction of them as DT and
multiplatform-enabled platforms instead.
- OMAP4 controller code register define diet. They defined a lot of
registers that were never actually used, etc.
- Move of some of the Tegra platform code (PMC, APBIO, fuse,
powergate) to drivers/soc so it can be shared with 64-bit code.
This also converts them over to traditional driver models where
possible.
- Removal of legacy gpio-samsung driver, since the last users have
been removed (moved to pinctrl)
Plus a bunch of smaller changes for various platforms that sort of
dissapear in the diffstat for the above. clps711x cleanups, shmobile
header file refactoring/moves for multiplatform friendliness, some
misc cleanups, etc"

Merge branch 'timers-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull timer and time updates from Thomas Gleixner:
"A rather large update of timers, timekeeping & co
- Core timekeeping code is year-2038 safe now for 32bit machines.
Now we just need to fix all in kernel users and the gazillion of
user space interfaces which rely on timespec/timeval :)
- Better cache layout for the timekeeping internal data structures.
- Proper nanosecond based interfaces for in kernel users.
- Tree wide cleanup of code which wants nanoseconds but does hoops
and loops to convert back and forth from timespecs. Some of it
definitely belongs into the ugly code museum.
- Consolidation of the timekeeping interface zoo.
- A fast NMI safe accessor to clock monotonic for tracing. This is a
long standing request to support correlated user/kernel space
traces. With proper NTP frequency correction it's also suitable
for correlation of traces accross separate machines.
- Checkpoint/restart support for timerfd.
- A few NOHZ[_FULL] improvements in the [hr]timer code.
- Code move from kernel to kernel/time of all time* related code.
- New clocksource/event drivers from the ARM universe. I'm really
impressed that despite an architected timer in the newer chips SoC
manufacturers insist on inventing new and differently broken SoC
specific timers.
[ Ed. "Impressed"? I don't think that word means what you think it means ]
- Another round of code move from arch to drivers. Looks like most
of the legacy mess in ARM regarding timers is sorted out except for
a few obnoxious strongholds.
- The usual updates and fixlets all over the place"

Merge branch 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm
Pull ARM updates from Russell King:
"Included in this update:
- perf updates from Will Deacon:
The main changes are callchain stability fixes from Jean Pihet and
event mapping and PMU name rework from Mark Rutland
The latter is preparatory work for enabling some code re-use with
arm64 in the future.
- updates for nommu from Uwe Kleine-König:
Two different fixes for the same problem making some ARM nommu
configurations not boot since 3.6-rc1. The problem is that
user_addr_max returned the biggest available RAM address which
makes some copy_from_user variants fail to read from XIP memory.
- deprecate legacy OMAP DMA API, in preparation for it's removal.
The popular drivers have been converted over, leaving a very small
number of rarely used drivers, which hopefully can be converted
during the next cycle with a bit more visibility (and hopefully
people popping out of the woodwork to help test)
- more tweaks for BE systems, particularly with the kernel image
format. In connection with this, I've cleaned up the way we
generate the linker script for the decompressor.
- removal of hard-coded assumptions of the kernel stack size, making
everywhere depend on the value of THREAD_SIZE_ORDER.
- MCPM updates from Nicolas Pitre.
- Make it easier for proper CPU part number checks (which should
always include the vendor field).
- Assembly code optimisation - use the "bx" instruction when
returning from a function on ARMv6+ rather than "mov pc, reg".
- Save the last kernel misaligned fault location and report it via
the procfs alignment file.
- Clean up the way we create the initial stack frame, which is a
repeated pattern in several different locations.
- Support for 8-byte get_user(), needed for some DRM implementations.
- mcs locking from Will Deacon.
- Save and restore a few more Cortex-A9 registers (for errata
workarounds)
- Fix various aspects of the SWP emulation, and the ELF hwcap for the
SWP instruction.
- Update LPAE logic for pte_write and pmd_write to make it more
correct.
- Support for Broadcom Brahma15 CPU cores.
- ARM assembly crypto updates from Ard Biesheuvel"
