| * MIPS: uprobes: Restore thread.trap_nrTiezhu Yang2023-04-241-0/+1
| | | | | | | | | | | | | | | | | | | | thread.trap_nr is saved in arch_uprobe_pre_xol(), it should be restored in arch_uprobe_{post,abort}_xol() accordingly, actually it was only done in the post function, just do it in the abort function too, this change is similar with x86 and powerpc.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the special case where p = mmap(NULL, ALLOC_SIZE, PROT_READ, MAP_PRIVATE | MAP_ANONYMOUS | MAP_POPULATE, -1, 0); is followed by rc = mprotect(p, ALLOC_SIZE, PROT_NONE); the _PAGE_SPECIAL bit in the page tables will be cleared by mistake and the later unmapped operations will incorrectly modify the struct page for the the zero page. This sequence occurs in the madvise05 test of the Linux Test Project suite of tests. This was discovered while testing an older version of the kernel (5.4.17) on a MIPS device. Unfortunately, support for this device is not available in newer kernels, so I can't test this with the latest Linux kernel code. It looks like the problem exists in newer kernels, but I can't verify it. Except for the LTP test, this sequence of calls is probably not common. Passing it along in the hope it will be useful to someone. Signed-off-by: Henry Willard <henry.willard@oracle.com> Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de>
| * MIPS: Sink body of check_bugs_early() into its only call siteNathan Chancellor2023-04-222-7/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If check_bugs_early() is not inlined, which a compiler is free to do after commit ac7c3e4ff401 ("compiler: enable CONFIG_OPTIMIZE_INLINING forcibly"), modpost would warn that check_bugs_early(), a non-init function, refers to check_bugs64_early(), which is marked __init. This would not result in any run time issues, as check_bugs_early() is only called from setup_arch(), which is marked __init. To avoid this potential warning, just sink the body of check_bugs_early() into its single call site in setup_arch().

| * MIPS: Mark check_bugs() as __initNathan Chancellor2023-04-221-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After commit ac7c3e4ff401 ("compiler: enable CONFIG_OPTIMIZE_INLINING forcibly"), a compiler may choose not to inline a function marked with just 'inline'. If check_bugs() is not inlined into start_kernel(), which occurs when building with clang after commit 9ea7e6b62c2b ("init: Mark [arch_call_]rest_init() __noreturn"), modpost complains with: WARNING: modpost: vmlinux.o: section mismatch in reference: check_bugs (section: .text) -> check_bugs32 (section: .init.text) check_bugs() is only called from start_kernel(), which itself is marked __init, so there would not be any issues at run time. Make it obvious to modpost that this call chain is safe by marking check_bugs() as __init, which fixes the warning.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When building with clang's integrated assembler, it points out that the CONFIG_CPU_HAS_DIEI versions of local_irq_enable and local_irq_disable have a named parameter that is not used in the body of the macro and it thinks that $8 is a positional parameter, rather than a register: arch/mips/include/asm/asmmacro.h:48:2: warning: macro defined with named parameters which are not used in macro body, possible positional parameter found in body which will have no effect .macro local_irq_enable reg=$8 ^ The comment above the function that performs this check in LLVM notes that the warning may trigger in this case, even though it is not problematic. It is easy enough to clean this up by just omitting the named parameter for this version of the macro, as it is entirely unused.

| | | | | | | | | | | | | | | | Move the SoC register value queries and tests to specific functions, to remove repetition of logic. No functional changes intended Signed-off-by: Sergio Paracuellos <sergio.paracuellos@gmail.com> Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de>
