This adds a common board file for almost all of the "simple" PowerPC 44x boards that exist today. This is intended to be a single place to add support for boards that do not differ in platform support from most of the evaluation boards that are used as reference platforms. Boards that have specific requirements or custom hardware setup should still have their own board.c file. Signed-off-by: NJosh Boyer <jwboyer@linux.vnet.ibm.com>

The file arch/powerpc/kernel/sysfs.c is currently only compiled for 64-bit kernels. It contain code to register CPU sysdevs in sysfs and add various properties such as cache topology and raw access by root to performance monitor counters (PMCs). A lot of that can be re-used as is on 32-bits. This makes the file be built for both, with appropriate ifdef'ing for the few bits that are really 64-bit specific, and adds some support for the raw PMCs for 75x and 74xx processors.

When removing a directory, the sysfs core takes care of removing files in the directory (see sysfs_remove_dir()). So when we are about to delete a kobject (and thus cause its sysfs directory to be removed), we don't have to explicitly remove the files attached to it, although it's harmless to do so.

Some time ago, a copies of the upstream dtc and libfdt sources were included in the kernel tree to avoid having these as external dependencies for building the kernel. Since then development on the upstream dtc and libfdt has continued. This updates the in-kernel versions to match the recently released upstream dtc version 1.2.0.

There are now two almost identical implementations of an MSI bitmap allocator, one in mpic_msi.c and the other in fsl_msi.c. Merge them together and put the result in msi_bitmap.c. Some of the MPIC bits will remain to provide a nicer interface for the MPIC users. In the process we fix two buglets. The first is that the allocation routines, now msi_bitmap_alloc_hwirqs(), returned an unsigned result, even though they use -1 to indicate allocation failure. Although all the callers were checking correctly, it is much better for the routine to just return an int. At least until someone wants > ~2 billion MSIs. The second buglet is that the device tree reservation logic only allowed power-of-two reservations. AFAICT that didn't effect any existing code but it's nicer if we can reserve arbitrary irqs from MSI use. We also add some selftests, which exposed the two buglets and now test for them, as well as some basic sanity tests. The tests are only built when CONFIG_DEBUG_KERNEL=y.

There is a small passage of code in ret_from_except_lite which is only required on iSeries. For a multi-platform kernel on non-iSeries machines this means we end up executing ~15 nops in ret_from_except_lite. It would be nicer if non-iSeries could skip the code entirely, and on iSeries we can jump out of line to execute the code. I have no performance numbers to justify this, other than the assertion that executing 15 nops takes longer than executing 0.

Recent of_platform changes made of_bus_type_init() overwrite the bus type's .dev_attrs list, meaning that the "name" attribute that ibmebus devices previously had is no longer present. This is a user-visible regression which breaks the userspace eHCA support, since the eHCA userspace driver relies on the name attribute to check for valid adapters. This fixes it by providing the "name" attribute in the generic OF device code instead. Tested on POWER.

Quoting Mike Travis in "x86: cleanup early per cpu variables/accesses v4" (23ca4bba): The DEFINE macro defines the per_cpu variable as well as the early map and pointer. It also initializes the per_cpu variable and map elements to "_initvalue". The early_* macros provide access to the initial map (usually setup during system init) and the early pointer. This pointer is initialized to point to the early map but is then NULL'ed when the actual per_cpu areas are setup. After that the per_cpu variable is the correct access to the variable. As these variables are NULL'ed before __init sections are dropped (in setup_per_cpu_maps), they can be safely annotated as __ref.
