ARM: SoC: late updates
A couple of late-merged changes that would be useful to get in this
merge window:
- Driver support for reset of audio complex on Meson platforms. The
audio driver went in this merge window, and these changes have been
in -next for a while (just not in our tree).
- Power management fixes for IOMMU on Rockchip platforms, getting
closer to kexec working on them, including Chromebooks.
- Another pass updating "arm,psci" -> "psci" for some properties that
have snuck in since last time it was done.

arm64: rockchip: Force CONFIG_PM on Rockchip systems
A number of the Rockchip-specific drivers (IOMMU, display controllers) are now assuming that CONFIG_PM is set, and may completely misbehave if that's not the case. Since there is hardly any reason for this configuration option not to be selected anyway, let's require it (in the same way Tegra already does).

ARM: Device-tree updates
Business as usual -- the bulk of our changes are to devicetree files
with new hardware support, new SoCs and platforms, and new board types.
New SoCs/platforms:
- Raspberry Pi Compute Module (CM1) and IO board
- i.MX6SSL from NXP
- Renesas RZ/N1D SoC (R9A06G032), Dual Cortex-A7 with Ethernet, CAN and
PLC interfaces
- TI AM654 SoC, Quad Cortex-A53, safety subsystem with Cortex-R5
controllers, communication and PRU subsystem and lots of other
interfaces (PCIe, USB3, etc).
New boards and systems:
- Several Atmel at91-based boards from Laird
- Marvell Armada388-based Helios4 board from SolidRun
- Samsung Aires-based phones (s5pv210)
- Allwinner A64-based Pinebook laptop
In addition to the above, there's the usual amount of new devices
described on existing platforms, fixes and tweaks and new minor variants
of boards/platforms.

ARM: 32-bit SoC platform updates
Most of the SoC updates in this cycle are cleanups and moves to more
modern infrastructure:
- Davinci was moved to common clock framework
- OMAP1-based Amstrad E3 "Superphone" saw a bunch of cleanups to the
keyboard interface (bitbanged AT keyboard via GPIO).
- Removal of some stale code for Renesas platforms
- Power management improvements for i.MX6LL

arch: enable relative relocations for arm64, power and x86
Patch series "add support for relative references in special sections", v10. This adds support for emitting special sections such as initcall arrays, PCI fixups and tracepoints as relative references rather than absolute references. This reduces the size by 50% on 64-bit architectures, but more importantly, it removes the need for carrying relocation metadata for these sections in relocatable kernels (e.g., for KASLR) that needs to be fixed up at boot time. On arm64, this reduces the vmlinux footprint of such a reference by 8x (8 byte absolute reference + 24 byte RELA entry vs 4 byte relative reference) Patch #3 was sent out before as a single patch. This series supersedes the previous submission. This version makes relative ksymtab entries dependent on the new Kconfig symbol HAVE_ARCH_PREL32_RELOCATIONS rather than trying to infer from kbuild test robot replies for which architectures it should be blacklisted. Patch #1 introduces the new Kconfig symbol HAVE_ARCH_PREL32_RELOCATIONS, and sets it for the main architectures that are expected to benefit the most from this feature, i.e., 64-bit architectures or ones that use runtime relocations. Patch #2 add support for #define'ing __DISABLE_EXPORTS to get rid of ksymtab/kcrctab sections in decompressor and EFI stub objects when rebuilding existing C files to run in a different context. Patches #4 - #6 implement relative references for initcalls, PCI fixups and tracepoints, respectively, all of which produce sections with order ~1000 entries on an arm64 defconfig kernel with tracing enabled. This means we save about 28 KB of vmlinux space for each of these patches. [From the v7 series blurb, which included the jump_label patches as well]: For the arm64 kernel, all patches combined reduce the memory footprint of vmlinux by about 1.3 MB (using a config copied from Ubuntu that has KASLR enabled), of which ~1 MB is the size reduction of the RELA section in .init, and the remaining 300 KB is reduction of .text/.data. This patch (of 6): Before updating certain subsystems to use place relative 32-bit relocations in special sections, to save space and reduce the number of absolute relocations that need to be processed at runtime by relocatable kernels, introduce the Kconfig symbol and define it for some architectures that should be able to support and benefit from it.

kernel/dma: remove unsupported gfp_mask parameter from dma_alloc_from_contiguous()
The CMA memory allocator doesn't support standard gfp flags for memory
allocation, so there is no point having it as a parameter for
dma_alloc_from_contiguous() function. Replace it by a boolean no_warn
argument, which covers all the underlaying cma_alloc() function
supports.
This will help to avoid giving false feeling that this function supports
standard gfp flags and callers can pass __GFP_ZERO to get zeroed buffer,
what has already been an issue: see commit

mm: convert return type of handle_mm_fault() caller to vm_fault_t
Use new return type vm_fault_t for fault handler. For now, this is just
documenting that the function returns a VM_FAULT value rather than an
errno. Once all instances are converted, vm_fault_t will become a
distinct type.

arm64: mm: check for upper PAGE_SHIFT bits in pfn_valid()
ARM64's pfn_valid() shifts away the upper PAGE_SHIFT bits of the input
before seeing if the PFN is valid. This leads to false positives when
some of the upper bits are set, but the lower bits match a valid PFN.
For example, the following userspace code looks up a bogus entry in
/proc/kpageflags:
int pagemap = open("/proc/self/pagemap", O_RDONLY);
int pageflags = open("/proc/kpageflags", O_RDONLY);
uint64_t pfn, val;
lseek64(pagemap, [...], SEEK_SET);
read(pagemap, &pfn, sizeof(pfn));
if (pfn & (1UL << 63)) { /* valid PFN */
pfn &= ((1UL << 55) - 1); /* clear flag bits */
pfn |= (1UL << 55);
lseek64(pageflags, pfn * sizeof(uint64_t), SEEK_SET);
read(pageflags, &val, sizeof(val));
}
On ARM64 this causes the userspace process to crash with SIGSEGV rather
than reading (1 << KPF_NOPAGE). kpageflags_read() treats the offset as
valid, and stable_page_flags() will try to access an address between the
user and kernel address ranges.

arm64: Avoid calling stop_machine() when patching jump labels
Patching a jump label involves patching a single instruction at a time,
swizzling between a branch and a NOP. The architecture treats these
instructions specially, so a concurrently executing CPU is guaranteed to
see either the NOP or the branch, rather than an amalgamation of the two
instruction encodings.
However, in order to guarantee that the new instruction is visible, it
is necessary to send an IPI to the concurrently executing CPU so that it
discards any previously fetched instructions from its pipeline. This
operation therefore cannot be completed from a context with IRQs
disabled, but this is exactly what happens on the jump label path where
the hotplug lock is held and irqs are subsequently disabled by
stop_machine_cpuslocked(). This results in a deadlock during boot on
Hikey-960.
Due to the architectural guarantees around patching NOPs and branches,
we don't actually need to stop_machine() at all on the jump label path,
so we can avoid the deadlock by using the "nosync" variant of our
instruction patching routine.

arm64 updates for 4.19
A bunch of good stuff in here:
- Wire up support for qspinlock, replacing our trusty ticket lock code
- Add an IPI to flush_icache_range() to ensure that stale instructions
fetched into the pipeline are discarded along with the I-cache lines
- Support for the GCC "stackleak" plugin
- Support for restartable sequences, plus an arm64 port for the selftest
- Kexec/kdump support on systems booting with ACPI
- Rewrite of our syscall entry code in C, which allows us to zero the
GPRs on entry from userspace
- Support for chained PMU counters, allowing 64-bit event counters to be
constructed on current CPUs
- Ensure scheduler topology information is kept up-to-date with CPU
hotplug events
- Re-enable support for huge vmalloc/IO mappings now that the core code
has the correct hooks to use break-before-make sequences
- Miscellaneous, non-critical fixes and cleanups

"A bunch of good stuff in here. Worth noting is that we've pulled in
the x86/mm branch from -tip so that we can make use of the core
ioremap changes which allow us to put down huge mappings in the

diffstat is because of the rseq selftest for arm64.

KVM: arm/arm64: vgic-v3: Add core support for Group0 SGIs
Although vgic-v3 now supports Group0 interrupts, it still doesn't deal with Group0 SGIs. As usually with the GIC, nothing is simple: - ICC_SGI1R can signal SGIs of both groups, since GICD_CTLR.DS==1 with KVM (as per 8.1.10, Non-secure EL1 access) - ICC_SGI0R can only generate Group0 SGIs - ICC_ASGI1R sees its scope refocussed to generate only Group0 SGIs (as per the note at the bottom of Table 8-14) We only support Group1 SGIs so far, so no material change.

ICC_SGI1R is a 64bit system register, even on AArch32. It is thus pointless to have such an encoding in the 32bit cp15 array. Let's drop it. Reviewed-by: Eric Auger <eric.auger@redhat.com> Acked-by: Christoffer Dall <christoffer.dall@arm.com> Signed-off-by: Marc Zyngier <marc.zyngier@arm.com> |

crypto: arm64/ghash-ce - replace NEON yield check with block limit
Checking the TIF_NEED_RESCHED flag is disproportionately costly on cores with fast crypto instructions and comparatively slow memory accesses. On algorithms such as GHASH, which executes at ~1 cycle per byte on cores that implement support for 64 bit polynomial multiplication, there is really no need to check the TIF_NEED_RESCHED particularly often, and so we can remove the NEON yield check from the assembler routines. However, unlike the AEAD or skcipher APIs, the shash/ahash APIs take arbitrary input lengths, and so there needs to be some sanity check to ensure that we don't hog the CPU for excessive amounts of time. So let's simply cap the maximum input size that is processed in one go to 64 KB. Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> |

crypto: arm64 - revert NEON yield for fast AEAD implementations
As it turns out, checking the TIF_NEED_RESCHED flag after each iteration results in a significant performance regression (~10%) when running fast algorithms (i.e., ones that use special instructions and operate in the < 4 cycles per byte range) on in-order cores with comparatively slow memory accesses such as the Cortex-A53. Given the speed of these ciphers, and the fact that the page based nature of the AEAD scatterwalk API guarantees that the core NEON transform is never invoked with more than a single page's worth of input, we can estimate the worst case duration of any resulting scheduling blackout: on a 1 GHz Cortex-A53 running with 64k pages, processing a page's worth of input at 4 cycles per byte results in a delay of ~250 us, which is a reasonable upper bound. So let's remove the yield checks from the fused AES-CCM and AES-GCM routines entirely. This reverts commit |
