.gitignore	RISC-V: mm: Add tests for RISC-V mm Add tests that enforce mmap hint address behavior. mmap should default to sv48. mmap will provide an address at the highest address space that can fit into the hint address, unless the hint address is less than sv39 and not 0, then it will return a sv39 address. These tests are split into two files: mmap_default.c and mmap_bottomup.c because a new process must be exec'd in order to change the mmap layout. The run_mmap.sh script sets the stack to be unlimited for the mmap_bottomup.c test which triggers a bottomup layout.

mmap_test.h	tools: selftests: riscv: Fix compile warnings in mm tests [ Upstream commit 12c16919652b5873f524c8b361336ecfa5ce5e6b ] When building the mm tests with a riscv32 compiler, we see a range of shift-count-overflow errors from shifting 1UL by more than 32 bits in do_mmaps(). Since, the relevant code is only called from code that is gated by __riscv_xlen == 64, we can just apply the same gating to do_mmaps().
