The TREE08 Kconfig fragment does not enable tracing, which is appropriate for its test case. However, this can be inconvenient in cases where TREE08 locates RCU bugs. This commit therefore adds a TREE08-T that differs from TREE08 only in enabling CONFIG_RCU_TRACE. Signed-off-by: NPaul E.

This commit adds the --no-initrd argument to kvm.sh, which permits initrd to be contained in a root partition specified by the --bootargs argument. Without --no-initrd, the kernel build expects an initrd directory in the same rcutorture directory that contains bin and configs. Signed-off-by: NPaul E.

As it stands, the default kernel boot parameters generated from the Kconfig fragment will override any supplied with the .boot file that can optionally accompany a Kconfig fragment.

The --rcu-kvm argument was intended to allow the scripts to live in an alternate location. Unfortunately, this prevents the kvm.sh script from using common functions until after it finished parsing arguments, because it doesn't know where to find them until then. However, "cp -a" and "ln -s" work pretty well, so lack of an --rcu-kvm argument can be easily worked around. This commit therefore removes this argument. Signed-off-by: NPaul E.

The task of working out which flavor of qemu to use gets more complex as more types of CPUs are supported. Adding Power makes three in addition to 32-bit and 64-bit x86, so it is time to pull this out into a function. This commit therefore creates an identify_qemu function and also adds a --qemu-cmd command-line argument for the inevitable case where the identify_qemu cannot figure it out. Signed-off-by: NPaul E.

Pull vfs dentry reference count fix from Al Viro. This fixes a possible inode_permission NULL pointer dereference (and other problems) that were due to the root dentry count being decremented too much. In commit 48a066e7 ("RCU'd vfsmounts") the placement of clearing the LOOKUP_RCU bit changed, and we then returned failure of incrementing the lockref on the parent dentry with LOOKUP_RCU cleared. But that meant we needed to go through the same cleanup routines that the later failures did wrt LOOKUP_ROOT and nd->root. * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: fix bogus path_put() of nd->root after some unlazy_walk() failures

PTE_PROT_NONE means that a pte is present but does not have any read/write attributes. However, setting the memory type like pgprot_writecombine() is allowed and such bits overlap with PTE_PROT_NONE. This causes mmap/munmap issues in drivers that change the vma->vm_pg_prot on PROT_NONE mappings. This patch reverts the PTE_FILE/PTE_PROT_NONE shift in commit 59911ca4 (ARM64: mm: Move PTE_PROT_NONE bit) and moves PTE_PROT_NONE together with the other software bits.

Failure to grab reference to parent dentry should go through the same cleanup as nd->seq mismatch.
