commit dbe6f186 ("dma-mapping: mark dma_sync_single and dma_sync_sg as deprecated" conveniently broke every single SH build. In the future it would be great if people could at least bother figuring out how to use grep. Signed-off-by:

SH7786 is roughly identical to SH-X3 proto SMP, though there are only 2 CPUs. This just wraps in to the existing SH-X3 SMP code with some minor changes for SH7786, including wiring up the IPIs properly, enabling IRQ_PER_CPU, and so forth. Signed-off-by: -

set_pte_phys() presently uses the global flush_tlb_one(), which locks on SMP trying to do the IPI. As we have not even initialized the other CPUs at this point, switch to the local_ variant so the flush happens on the boot CPU. Signed-off-by: -

As noted in the previous patch, the NFSv4 client mount code currently has several limitations. If the mount path contains symlinks, or referrals, or even if it just contains a '..', then the client code in nfs4_path_walk() will fail with an error. This patch replaces the nfs4_path_walk()-based lookup with a helper function that sets up a private namespace to represent the namespace on the server, then uses the ordinary VFS and NFS path lookup code to walk down the mount path in that namespace. Signed-off-by:

The purpose of this patch is to improve the remote mount path lookup support for distributed filesystems such as the NFSv4 client. When given a mount command of the form "mount server:/foo/bar /mnt", the NFSv4 client is required to look up the filehandle for "server:/", and then look up each component of the remote mount path "foo/bar" in order to find the directory that is actually going to be mounted on /mnt. Following that remote mount path may involve following symlinks, crossing server-side mount points and even following referrals to filesystem volumes on other servers. Since the standard VFS path lookup code already supports walking paths that contain all these features (using in-kernel automounts for following referrals) we would like to be able to reuse that rather than duplicate the full path traversal functionality in the NFSv4 client code. This patch therefore defines a VFS helper function create_mnt_ns(), that sets up a temporary filesystem namespace and attaches a root filesystem to it. It exports the create_mnt_ns() and put_mnt_ns() function for use by filesystem modules. Signed-off-by:

SLAB uses get/put_online_cpus() which use a mutex which is itself only initialized when cpu_hotplug_init() is called. Currently we hang suring boot in SLAB due to doing that too late. Reported by James Bottomley and Sachin Sant (and possibly others). Debugged by Benjamin Herrenschmidt. This just removes the dynamic initialization of the data structures, and replaces it with a static one, avoiding this dependency entirely, and removing one unnecessary special initcall. Tested-by:

The recent deprecation of dma_sync_{sg,single} ironically broke Blackfin systems. This is because we don't define dma_sync_sg_for_cpu at all, so until the DMA asm-generic conversion/cleanup is done after the next release, simply stub out the dma_sync_sg_for_{cpu,device} functions.

We don't support the BF535 at all, and the exception 0x2A text specific to it is pretty verbose and confusing (since the behavior is simply odd), so punt it to keep the noise down. Signed-off-by:

Make sure we process the kernel command line before poking the hardware, so that we can process early printk. This helps ensure that if you boot a kernel configured for a different processor, something will be left in the log buffer. Signed-off-by:

Many aspects of the Blackfin memory map is exactly the same across all variants. Rather than copy and paste all of these duplicated values in each header, unify all of these into the common Blackfin memory map header file. In the process, push down BF561 SMP specific stuff to the BF561 specific header to keep the noise down. Signed-off-by: -

Rather than use "Linux" in the boot image name (as this is redundant -- the image type is already set to "linux"), use the CPU name. This makes it fairly obvious when a wrong image is accidentally booted. Otherwise there is no kernel output and you waste time scratching your head wondering wtf just happened. Signed-off-by:

The current cache options don't really represent the hardware features. They end up setting different aspects of the hardware so that the end result is to turn on/off the cache. Unfortunately, when we hit cache problems with the hardware, it's difficult to test different settings to root cause the problem. The current settings also don't cleanly allow for different caching behaviors with different regions of memory. So split the configure options such that they properly reflect the settings that are applied to the hardware. Signed-off-by:

We read the SWRST (Software Reset) register to get at the last reset state, and then we may configure the DOUBLE_FAULT bit to control behavior when a double fault occurs. But if the lower bits of the register is already set (like UART boot mode on a BF54x), we inadvertently make the system reset by writing to the SYSTEM_RESET field at the same time. So make sure the lower 4 bits are always cleared. Signed-off-by:

With the common IRQ code initializing much more of the irq_desc state, we can't blindly initialize it ourselves to the local bad_irq state. If we do, we end up wrongly clobbering many fields. So punt most of the bad irq code as the common layers will handle the default state, and simply call handle_bad_irq() directly when the IRQ we are processing is invalid. Signed-off-by: -
