There is, however, some 64-bit user code that intentionally uses int $0x80 to invoke 32-bit system calls. From what I've seen, basically all such code assumes that r8-r15 are all preserved, but the kernel clobbers r8-r11. Since I doubt that there's any code that depends on int $0x80 zeroing r8-r11, change the kernel to preserve them. I suspect that very little user code is broken by the old clobber, since r8-r11 are only rarely allocated by gcc, and they're clobbered by function calls, so they only way we'd see a problem is if the same function that invokes int $0x80 also spills something important to one of these registers. The current behavior seems to date back to the historical commit "[PATCH] x86-64 merge for 2.6.4". Before that, all regs were preserved. I can't find any explanation of why this change was made. Update the test_syscall_vdso_32 testcase as well to verify the new behavior, and it strengthens the test to make sure that the kernel doesn't accidentally permute r8..r15.

That had the effect of causing the existing dnotify_test in the filesystems directory to now be run as part of the default selftests test-run. Unfortunately dnotify_test is actually an infinite loop. Fix it by moving dnotify_test to TEST_GEN_PROGS_EXTENDED, which says that it's a generated file (ie. built) but should not be run as part of the default test suite run (it's an "extended" test). While we're here cleanup a few other things, devpts_pts should be in TEST_GEN_PROGS to indicate that it's built, and with the above two changes we no longer need a custom all or clean rule.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The recent commit 15a3204d24a3 ("powerpc/64s: Set assembler machine type to POWER4") set the machine type in our ASFLAGS when building the kernel, and removed some ".machine power4" directives from various asm files. This broke the selftests build on old toolchains (that don't assume Power4), because we build the kernel source files into the selftests using different ASFLAGS. The fix is simply to add -mpower4 to the selftest ASFLAGS as well. Fixes: 15a3204d24a3 ("powerpc/64s: Set assembler machine type to POWER4") Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>

In either case the tm-unavailable test should be skipped, otherwise it will fail with a SIGILL. That commit also sets this selftest to be called through the test harness as it's done for other TM selftests. Finally, it avoids using "ping" as a thread name since it's ambiguous and can be confusing when shown, for instance, in a kernel backtrace log.

It is possible to build from the root of the Linux tree, which will define ARCH, or to run make from the selftests/ directory itself, which has no provision for defining ARCH, so this change is to use the current definition (if any), or to check uname -m if undefined.

We can narrow it down by printing which test directory we're running in to /dev/kmsg, if it's writable.
