Merge tag 'riscv-for-linus-7.0-mw1' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux

Pull RISC-V updates from Paul Walmsley:

- Add support for control flow integrity for userspace processes.

This is based on the standard RISC-V ISA extensions Zicfiss and
Zicfilp

- Improve ptrace behavior regarding vector registers, and add some
selftests

- Optimize our strlen() assembly

- Enable the ISO-8859-1 code page as built-in, similar to ARM64, for
EFI volume mounting

- Clean up some code slightly, including defining copy_user_page() as
copy_page() rather than memcpy(), aligning us with other
architectures; and using max3() to slightly simplify an expression
in riscv_iommu_init_check()

This series adds support for 8D-8D-8D in SPI NAND, which can already be

Among the few spi-mem patches, they are needed for building the SPI NAND
changes (especially the ODTR introduction at the end) and therefore an
immutable tag will be needed for merging in the MTD tree (unless all the

arch/riscv: add dual vdso creation logic and select vdso based on hw

Shadow stack instructions are taken from the Zimop ISA extension,
which is mandated on RVA23. Any userspace with shadow stack
instructions in it will fault on hardware that doesn't have support
for Zimop. Thus, a shadow stack-enabled userspace can't be run on
hardware that doesn't support Zimop.

It's not known how Linux userspace providers will respond to this kind
of binary fragmentation. In order to keep kernel portable across
different hardware, 'arch/riscv/kernel/vdso_cfi' is created which has
Makefile logic to compile 'arch/riscv/kernel/vdso' sources with CFI
flags, and 'arch/riscv/kernel/vdso.c' is modified to select the
appropriate vdso depending on whether the underlying CPU implements
the Zimop extension. Since the offset of vdso symbols will change due
to having two different vdso binaries, there is added logic to include
a new generated vdso offset header and dynamically select the offset
(like for rt_sigreturn).

riscv/mm: Implement map_shadow_stack() syscall

As discussed extensively in the changelog for the addition of this
syscall on x86 ("x86/shstk: Introduce map_shadow_stack syscall") the
existing mmap() and madvise() syscalls do not map entirely well onto the
security requirements for shadow stack memory since they lead to windows
where memory is allocated but not yet protected or stacks which are not
properly and safely initialised. Instead a new syscall map_shadow_stack()
has been defined which allocates and initialises a shadow stack page.

This patch implements this syscall for riscv. riscv doesn't require
tokens to be setup by kernel because user mode can do that by
itself. However to provide compatibility and portability with other
architectues, user mode can specify token set flag.
