Merge patch series "RISC-V: Parse DT for Zkr to seed KASLR"
Jesse Taube <jesse@rivosinc.com> says:
Add functions to pi/fdt_early.c to help parse the FDT to check if
the isa string has the Zkr extension. Then use the Zkr extension to
seed the KASLR base address.
The first two patches fix the visibility of symbols.
* b4-shazam-merge:
RISC-V: Use Zkr to seed KASLR base address
RISC-V: pi: Add kernel/pi/pi.h
RISC-V: lib: Add pi aliases for string functions
RISC-V: pi: Force hidden visibility for all symbol references
