Palmer Dabbelt 8aeb7b17f0 RISC-V: Make mmap() with PROT_WRITE imply PROT_READ 
Commit 2139619bca ("riscv: mmap with PROT_WRITE but no PROT_READ is
invalid") made mmap() reject mappings with only PROT_WRITE set in an
attempt to fix an observed inconsistency in behavior when attempting
to read from a PROT_WRITE-only mapping. The root cause of this behavior
was actually that while RISC-V's protection_map maps VM_WRITE to
readable PTE permissions (since write-only PTEs are considered reserved
by the privileged spec), the page fault handler considered loads from
VM_WRITE-only VMAs illegal accesses. Fix the underlying cause by
handling faults in VM_WRITE-only VMAs (patch 1) and then re-enable
use of mmap(PROT_WRITE) (patch 2), making RISC-V's behavior consistent
with all other architectures that don't support write-only PTEs.

Conor Dooley c45fc916c2 riscv: enable software resend of irqs 
The PLIC specification does not describe the interrupt pendings bits as
read-write, only that they "can be read". To allow for retriggering of
interrupts (and the use of the irq debugfs interface) enable
HARDIRQS_SW_RESEND for RISC-V.

This is because the mm->context.vdso_info is NULL in vfork case. From
another side, mm->context.vdso_info either points to vdso info
for RV64 or vdso info for compat, there's no need to bloat riscv's
mm_context_t, we can handle the difference when setup the additional
page for vdso.

Palmer Dabbelt f2913d006f RISC-V: Avoid dereferening NULL regs in die() 
I don't think we can actually die() without a regs pointer, but the
compiler was warning about a NULL check after a dereference.  It seems
prudent to just avoid the possibly-NULL dereference, given that when
die()ing the system is already toast so who knows how we got there.

Conor Dooley <mail@conchuod.ie> says:

From: Conor Dooley <conor.dooley@microchip.com>

The device trees produced automatically for the virt and spike machines
fail dt-validate on several grounds. Some of these need to be fixed in
the linux kernel's dt-bindings, but others are caused by bugs in QEMU.

Patches been sent that fix the QEMU issues [0], but a couple of them
need to be fixed in the kernel's dt-bindings. The first patches add
compatibles for "riscv,{clint,plic}0" which are present in drivers and
the auto generated QEMU dtbs.

Thanks to Rob Herring for reporting these issues [1],
Conor.

To reproduce the errors:

dt-validate -p /path/to/linux/kernel/Documentation/devicetree/bindings/processed-schema.json qemu.dtb

Conor Dooley 299824e68b dt-bindings: riscv: add new riscv,isa strings for emulators 
The QEMU virt and spike machines currently export a riscv,isa string of
"rv64imafdcsuh",

While the RISC-V foundation has been ratifying a bunch of extenstions
etc, the kernel has remained relatively static with what hardware is
supported - but the same is not true of QEMU. Using the virt machine
and running dt-validate on the dumped dtb fails, partly due to the
unexpected isa string.

Rather than enumerate the many many possbilities, change the pattern
to a regex, with the following assumptions:
- ima are required
- the single letter order is fixed & we don't care about things that
  can't even do "ima"
- the standard multi letter extensions are all in a "_z<foo>" format
  where the first letter of <foo> is a valid single letter extension
- _s & _h are used for supervisor and hyper visor extensions
- convention says that after the first two chars, a standard multi
  letter extension name could be an english word (ifencei anyone?) so
  it's not worth restricting the charset
- as the above is just convention, don't apply any charset restrictions
  to reduce future churn
- vendor ISA extensions begind with _x and have no charset restrictions
- we don't care about an e extension from an OS pov
- that attempting to validate the contents of the multiletter extensions
  with dt-validate beyond the formatting is a futile, massively verbose
  or unwieldy exercise at best

The following limitations also apply:
- multi letter extension ordering is not enforced. dt-schema does not
  appear to allow for named match groups, so the resulting regex would
  be even more of a headache
- ditto for the numbered extensions

Finally, add me as a maintainer of the binding so that when it breaks
in the future, I can be held responsible!

supported in user mode, but that requirement was removed in 2018 via
riscv-isa-manual commit 61cadb9 ("Provide new description of misaligned
load/store behavior compatible with privileged architecture.").  Since
the Linux uABI was already frozen at that point it's just been demoted
to part of the uABI, but that was never written down.

Wenting Zhang 10f6913c54 riscv: always honor the CONFIG_CMDLINE_FORCE when parsing dtb 
When CONFIG_CMDLINE_FORCE is enabled, cmdline provided by
CONFIG_CMDLINE are always used. This allows CONFIG_CMDLINE to be
used regardless of the result of device tree scanning.

This especially fixes the case where a device tree without the
chosen node is supplied to the kernel. In such cases,
early_init_dt_scan would return true. But inside
early_init_dt_scan_chosen, the cmdline won't be updated as there
is no chosen node in the device tree. As a result, CONFIG_CMDLINE
is not copied into boot_command_line even if CONFIG_CMDLINE_FORCE
is enabled. This commit allows properly update boot_command_line
in this situation.

Linus Torvalds 0e470763d8 Merge tag 'efi-next-for-v6.1' of git://git.kernel.org/pub/scm/linux/kernel/git/efi/efi 
Pull EFI updates from Ard Biesheuvel:
 "A bit more going on than usual in the EFI subsystem. The main driver
  for this has been the introduction of the LoonArch architecture last
  cycle, which inspired some cleanup and refactoring of the EFI code.
  Another driver for EFI changes this cycle and in the future is
  confidential compute.

  The LoongArch architecture does not use either struct bootparams or DT
  natively [yet], and so passing information between the EFI stub and
  the core kernel using either of those is undesirable. And in general,
  overloading DT has been a source of issues on arm64, so using DT for
  this on new architectures is a to avoid for the time being (even if we
  might converge on something DT based for non-x86 architectures in the
  future). For this reason, in addition to the patch that enables EFI
  boot for LoongArch, there are a number of refactoring patches applied
  on top of which separate the DT bits from the generic EFI stub bits.
  These changes are on a separate topich branch that has been shared
  with the LoongArch maintainers, who will include it in their pull
  request as well. This is not ideal, but the best way to manage the
  conflicts without stalling LoongArch for another cycle.

  Another development inspired by LoongArch is the newly added support
  for EFI based decompressors. Instead of adding yet another
  arch-specific incarnation of this pattern for LoongArch, we are
  introducing an EFI app based on the existing EFI libstub
  infrastructure that encapulates the decompression code we use on other
  architectures, but in a way that is fully generic. This has been
  developed and tested in collaboration with distro and systemd folks,
  who are eager to start using this for systemd-boot and also for arm64
  secure boot on Fedora. Note that the EFI zimage files this introduces
  can also be decompressed by non-EFI bootloaders if needed, as the
  image header describes the location of the payload inside the image,
  and the type of compression that was used. (Note that Fedora's arm64
  GRUB is buggy [0] so you'll need a recent version or switch to
  systemd-boot in order to use this.)

  Finally, we are adding TPM measurement of the kernel command line
  provided by EFI. There is an oversight in the TCG spec which results
  in a blind spot for command line arguments passed to loaded images,
  which means that either the loader or the stub needs to take the
  measurement. Given the combinatorial explosion I am anticipating when
  it comes to firmware/bootloader stacks and firmware based attestation
  protocols (SEV-SNP, TDX, DICE, DRTM), it is good to set a baseline now
  when it comes to EFI measured boot, which is that the kernel measures
  the initrd and command line. Intermediate loaders can measure
  additional assets if needed, but with the baseline in place, we can
  deploy measured boot in a meaningful way even if you boot into Linux
  straight from the EFI firmware.

  Summary:

   - implement EFI boot support for LoongArch

   - implement generic EFI compressed boot support for arm64, RISC-V and
     LoongArch, none of which implement a decompressor today

   - measure the kernel command line into the TPM if measured boot is in
     effect

   - refactor the EFI stub code in order to isolate DT dependencies for
     architectures other than x86

   - avoid calling SetVirtualAddressMap() on arm64 if the configured
     size of the VA space guarantees that doing so is unnecessary

   - move some ARM specific code out of the generic EFI source files

   - unmap kernel code from the x86 mixed mode 1:1 page tables"

 "We have some late breaking reports that a patch series to rework clk
  rate range support broke boot on some devices, so I've left that
  branch out of this. Hopefully we can get to that next week, or punt on
  it and let it bake another cycle. That means we don't really have any
  changes to the core framework this time around besides a few typo
  fixes. Instead this is all clk driver updates and fixes.

  The usual suspects are here (again), with Qualcomm dominating the
  diffstat. We look to have gained support for quite a few new Qualcomm
  SoCs and Dmitry worked on updating many of the existing Qualcomm
  drivers to use clk_parent_data. After that we have MediaTek drivers
  getting some much needed updates, in particular to support GPU DVFS.
  There are also quite a few Samsung clk driver patches, but that's
  mostly because there was a maintainer change and so last release we
  missed some of those patches.

  Overall things look normal, but I'm slowly reviewing core framework
  code nowadays and that shows given the rate range patches had to be
  yanked last minute. Let's hope this situation changes soon.

Linus Torvalds f01603979a Merge tag 'gpio-updates-for-v6.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux 
Pull gpio updates from Bartosz Golaszewski:
 "We have a single new driver, support for a bunch of new models,
  improvements in drivers and core gpiolib code as well device-tree
  bindings changes.

  Summary:

  New driver:
   - IMX System Controller Unit GPIOs

  GPIO core:
   - add fdinfo output for the GPIO character device file descriptors
     (allows user-space to determine which processes own which GPIO
     lines)
   - improvements to OF GPIO code
   - new quirk for Asus UM325UAZ in gpiolib-acpi
   - new quirk for Freescale SPI in gpiolib-of

  Driver improvements:
   - add a new macro that reduces the amount of boilerplate code in ISA
     drivers and use it in relevant drivers
   - support two new models in gpio-pca953x
   - support new model in gpio-f7188x
   - convert more drivers to use immutable irq chips
   - other minor tweaks

  Device-tree bindings:
   - add DT bindings for gpio-imx-scu
   - convert Xilinx GPIO bindings to YAML
   - reference the properties from the SPI peripheral device-tree
     bindings instead of providing custom ones in the GPIO controller
     document
   - add parsing of GPIO hog nodes to the DT bindings for gpio-mpfs-gpio
   - relax the node name requirements in gpio-stmpe
   - add new models for gpio-rcar and gpio-pxa95xx
   - add a new vendor prefix: Diodes (for Diodes, Inc.)

  Misc:
   - pulled in the immutable branch from the x86 platform drivers tree
     including support for a new simatic board that depends on GPIO
     changes"

Linus Torvalds 62e6e5940c Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi 
Pull SCSI updates from James Bottomley:
 "Updates to the usual drivers (qla2xxx, lpfc, ufs, hisi_sas, mpi3mr,
  mpt3sas, target). The biggest change (from my biased viewpoint) being
  that the mpi3mr now attached to the SAS transport class, making it the
  first fusion type device to do so.

  Beyond the usual bug fixing and security class reworks, there aren't a
  huge number of core changes"
