Pull RISC-V fixes from Paul Walmsley: "One important fix for RISC-V: - Redirect any incoming syscall with an ID less than -1 to sys_ni_syscall, rather than allowing them to fall through into the syscall handler. and two minor build fixes: - Export __asm_copy_{from,to}_user() from where they are defined. This fixes a build error triggered by some randconfigs. - Export flush_icache_all(). I'd resisted this before, since historically we didn't want modules to be able to flush the I$ directly; but apparently everyone else is doing it now" * tag 'riscv/for-v5.5-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux: riscv: export flush_icache_all to modules riscv: reject invalid syscalls below -1 riscv: fix compile failure with EXPORT_SYMBOL() & !MMU

Pull /proc/locks formatting fix from Jeff Layton: "This is a trivial fix for a _very_ long standing bug in /proc/locks formatting. Ordinarily, I'd wait for the merge window for something like this, but it is making it difficult to validate some overlayfs fixes. I've also gone ahead and marked this for stable" * tag 'locks-v5.5-1' of git://git.kernel.org/pub/scm/linux/kernel/git/jlayton/linux: locks: print unsigned ino in /proc/locks

locks: print unsigned ino in /proc/locks

An ino is unsigned, so display it as such in /proc/locks. Cc: stable@vger.kernel.org Signed-off-by: Amir Goldstein Signed-off-by: Jeff Layton

riscv: export flush_icache_all to modules

2019-12-28T05:51:01Z

This is needed by LKDTM (crash dump test module), it calls flush_icache_range(), which on RISC-V turns into flush_icache_all(). On other architectures, the actual implementation is exported, so follow that precedence and export it here too. Fixes build of CONFIG_LKDTM that fails with: ERROR: "flush_icache_all" [drivers/misc/lkdtm/lkdtm.ko] undefined! Signed-off-by: Olof Johansson Signed-off-by: Paul Walmsley

riscv: reject invalid syscalls below -1

2019-12-28T05:50:57Z

Running "stress-ng --enosys 4 -t 20 -v" showed a large number of kernel oops with "Unable to handle kernel paging request at virtual address" message. This happens when enosys stressor starts testing random non-valid syscalls. I forgot to redirect any syscall below -1 to sys_ni_syscall. With the patch kernel oops messages are gone while running stress-ng enosys stressor.

riscv: fix compile failure with EXPORT_SYMBOL() & !MMU

2019-12-28T05:44:36Z

When support for !MMU was added, the declaration of __asm_copy_to_user() & __asm_copy_from_user() were #ifdefed out hence their EXPORT_SYMBOL() give an error message like: .../riscv_ksyms.c:13:15: error: '__asm_copy_to_user' undeclared here .../riscv_ksyms.c:14:15: error: '__asm_copy_from_user' undeclared here Since these symbols are not defined with !MMU it's wrong to export them. Same for __clear_user() (even though this one is also declared in include/asm-generic/uaccess.h and thus doesn't give an error message). Fix this by doing the EXPORT_SYMBOL() directly where these symbols are defined: inside lib/uaccess.S itself.
