[PATCH for-9.0 1/4] linux-headers: Update to Linux v6.7-rc3
Posted by Daniel Henrique Barboza 12 months ago 
We'll add a new RISC-V linux-header file, but first let's update all
headers.

Headers for 'asm-loongarch' were added in this update.

 old commit msg:

add asm-riscv/ptrace.h

KVM Vector support for RISC-V requires import linux-header
 arch/riscv/include/uapi/asm/ptrace.h.
