Charlie Jenkins <charlie@rivosinc.com> says: Make sv48 the default address space for mmap as some applications currently depend on this assumption. Users can now select a desired address space using a non-zero hint address to mmap. Previously, requesting the default address space from mmap by passing zero as the hint address would result in using the largest address space possible. Some applications depend on empty bits in the virtual address space, like Go and Java, so this patch provides more flexibility for application developers. * b4-shazam-merge: RISC-V: mm: Document mmap changes RISC-V: mm: Update pgtable comment documentation RISC-V: mm: Add tests for RISC-V mm RISC-V: mm: Restrict address space for sv39,sv48,sv57 Link: https://lore.kernel.org/r/20230809232218.849726-1-charlie@rivosinc.com Signed-off-by: Palmer Dabbelt <palmer@rivosinc.com> |
