* of/mdio: Fix some endianness problems.David Daney2010-12-241-9/+17
| | | | | | | | | | | | In of_mdiobus_register(), the __be32 *addr variable is dereferenced. This will not work on little-endian targets. Also since it is unsigned, checking for less than zero is redundant. Fix these two issues.

* of/address: use proper endianess in get_flagsSebastian Andrzej Siewior2010-12-233-30/+32
| | | | | | | | | | | | | | This patch changes u32 to __be32 for all "ranges", "prop" and "addr" and such. Those variables are pointing to the device tree which contains integers in big endian format. Most functions are doing it right because of_read_number() is doing the right thing for them. of_bus_isa_get_flags(), of_bus_pci_get_flags() and of_bus_isa_map() were accessing the data directly and were doing it wrong.

* of: Add support for linking device tree blobs into vmlinuxDirk Brandewie2010-12-233-2/+49
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for linking device tree blob(s) into vmlinux. Modifies asm-generic/vmlinux.lds.h to add linking .dtb sections into vmlinux. To maintain compatiblity with the of/fdt driver code platforms MUST copy the blob to a non-init memory location before the kernel frees the .init.* sections in the image. Modifies scripts/Makefile.lib to add a kbuild command to compile DTS files to device tree blobs and a rule to create objects to wrap the blobs for linking. STRUCT_ALIGNMENT is defined in vmlinux.lds.h for use in the rule to create wrapper objects for the dtb in Makefile.lib. The STRUCT_ALIGN() macro in vmlinux.lds.h is modified to use the STRUCT_ALIGNMENT definition. The DTB's are placed on 32 byte boundries to allow parsing the blob with driver/of/fdt.c during early boot without having to copy the blob to get the structure alignment GCC expects. A DTB is linked in by adding the DTB object to the list of objects to be linked into vmlinux in the archtecture specific Makefile using obj-y += foo.dtb.o Signed-off-by: Dirk Brandewie <dirk.brandewie@gmail.com> Acked-by: Michal Marek <mmarek@suse.cz> [grant.likely@secretlab.ca: cleaned up whitespace inconsistencies] Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

The first bug will only show up with broken xHCI hosts with Extended Capabilities registers that have duplicate port speed entries for the same port. The idea with the original code was to set the port_array entry to -1 if the duplicate port speed entry said the port was a different speed than the original port speed entry. That would mean that later, the port would not be exposed to the USB core. Unfortunately, I forgot a continue statement, and the port_array entry would just be overwritten in the next line. The second bug would happen if there are conflicting port speed registers (so that some entry in port_array is -1), or one of the hardware port registers was not described in the port speed registers (so that some entry in port_array is 0). The code that sets up the usb2_ports array would accidentally claim those ports. That wouldn't really cause any user-visible issues, but it is a bug. This patch should go into the stable trees that have the port array and USB 3.0 port disabling prevention patches. Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com> Cc: stable@kernel.org

While it would be possible to fix the issue, there are some other lock troubles, like to the presence of lock code at free_btres_lock(). It is possible to fix, but the better is to just use the core-assisted locking schema. This way, V4L2 core will serialize access to all ioctl's/open/close/mmap/read/poll operations, avoiding to have two processes accessing the hardware at the same time. Also, as there's just one lock, instead of 3, there's no risk of dead locks. The net result is a cleaner code, with just one lock.

SH-Mobile ARM platforms using multiple interrupt priority levels need this patch to fix a potential dead lock that may occur if multiple interrupts with different levels are pending simultaneously. The default INTC configuration is to use the same priority level for all interrupts, so this issue does not trigger by default. It is however common for board code to override the interrupt priority for certain interrupt sources depending on the application. Without this fix such boards may lock up. In detail, this patch updates the INTC code in entry-macro.S to make sure that the INTLVLA register gets set as expected. To trigger this bug modify the board specific code to adjust the interrupt priority level for the ethernet chip. After changing the priority level simply use flood ping to drown the board with interrupts. This patch applies to INTCA-based processors such as sh7372, sh7377 and sh7372. GIC-based processors are not affected. Suitable for v2.6.37-rc and stable from v2.6.34 to v2.6.36.

The callers sh_cmt_{start,stop}() already have lock. But another callers sh_cmt_clock_event_{start,next}() does not. Now sh_cmt_set_next() does not lock by itself. All the callers should hold spin-lock before calling it.
