Linux kernel source tree

Conor Dooley <conor.dooley@microchip.com> says: Based on my latest iteration of deprecating riscv,isa [1], here's an implementation of the new properties for Linux. The first few patches, up to "RISC-V: split riscv_fill_hwcap() in 3", are all prep work that further tames some of the extension related code, on top of my already applied series that cleans up the ISA string parser. Perhaps "RISC-V: shunt isa_ext_arr to cpufeature.c" is a bit gratuitous, but I figured a bit of coalescing of extension related data structures would be a good idea. Note that riscv,isa will still be used in the absence of the new properties. Palmer suggested adding a Kconfig option to turn off the fallback for DT, which I have gone and done. It's locked behind the NONPORTABLE option for good reason. * b4-shazam-merge: RISC-V: provide Kconfig & commandline options to control parsing "riscv,isa" RISC-V: try new extension properties in of_early_processor_hartid() RISC-V: enable extension detection from dedicated properties RISC-V: split riscv_fill_hwcap() in 3 RISC-V: add single letter extensions to riscv_isa_ext RISC-V: add missing single letter extension definitions RISC-V: repurpose riscv_isa_ext array in riscv_fill_hwcap() RISC-V: shunt isa_ext_arr to cpufeature.c RISC-V: drop a needless check in print_isa_ext() RISC-V: don't parse dt/acpi isa string to get rv32/rv64 RISC-V: Provide a more helpful error message on invalid ISA strings Link: https://lore.kernel.org/r/20230713-target-much-8ac624e90df8@wendy Signed-off-by: Palmer Dabbelt <palmer@rivosinc.com> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
