L3 Cache Partitioning allows selecting which of the 4 L3 subcaches can be used for evictions by the L2 cache of each compute unit. By writing a 4-bit hexadecimal mask into the the sysfs file /sys/devices/system/cpu/cpuX/cache/index3/subcaches, the user can set the enabled subcaches for a CPU. The settings are directly read from and written to the hardware, so there is no way to have contradicting settings for two CPUs belonging to the same compute unit. Writing will always overwrite any previous setting for a compute unit.

On multi-node CPUs we don't need the socket wide compute unit ID but the node-wide compute unit ID. Thus we need to normalize the value. This is similar to what we do with cpu_core_id. A compute unit is then identified by physical_package_id, node_id, and compute_unit_id.

Fix __key_link_end()'s attempt to fix up the quota if an error occurs. There are two erroneous cases: Firstly, we always decrease the quota if the preallocated replacement keyring needs cleaning up, irrespective of whether or not we should (we may have replaced a pointer rather than adding another pointer). Secondly, we never clean up the quota if we added a pointer without the keyring storage being extended (we allocate multiple pointers at a time, even if we're not going to use them all immediately). We handle this by setting the bottom bit of the preallocation pointer in __key_link_begin() to indicate that the quota needs fixing up, which is then passed to __key_link() (which clears the whole thing) and __key_link_end().

Relying on the access time of peripherals is unreliable - it depends on the speed of the CPU and the bus. On Versatile Express, these timeouts were expiring, causing the driver to fail. Add udelay(1) to ensure that they don't expire early, and adjust timeouts to give a reasonable margin over the response times. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

The EP93xx C and D GPIO ports are multiplexed with the Keypad Interface peripheral. At power-up they default into non-GPIO mode with the Key Matrix controller enabled so these ports are unusable for GPIO. Note that the Keypad Interface peripheral is only available in the EP9307, EP9312, and EP9315 processor variants. The keypad support will clear the DeviceConfig bits appropriately to enable the Keypad Interface when the driver is loaded. And, when the driver is unloaded it will set the bits to return the ports to GPIO mode. To make these ports available for GPIO after power-up on all EP93xx processor variants, set the KEYS and GONK bits in the DeviceConfig register. Similarly, the E, G, and H ports are multiplexed with the IDE Interface peripheral. At power-up these also default into non-GPIO mode. Note that the IDE peripheral is only available in the EP9312 and EP9315 processor variants. Since an IDE driver is not even available in mainline, set the EONIDE, GONIDE, and HONIDE bits in the DeviceConfig register so that these ports will be available for GPIO use after power-up.

Timers on Versatile Express mainboard are used as system clock/event sources. Driver assumes that they are clocked with 1MHz signal. Old V2M firmware apparently configured it by default, but on newer boards one can observe that "sleep 1" command takes over 30 seconds to finish, as the timers are fed with 32kHz instead... This patch performs required magic and also removes code clearing timer's control registers, as exactly the same operations are performed by the timer driver few jiffies later.

As no one seems to really know which configuration options tie up with which boards, I thought I'd do some investigation and try to work it out. After discussion with some folk in linaro, I think I have this nailed. The names are updated to use the name on the front of the appropriate board user guide for the various baseboards, which I've taken to be the official name for each board. I haven't significantly updated the descriptions for the tiles as that is even less clear - as far as I can see on ARMs website, there is no Cortex-A9 tile for Realview EB - only ARM11MPCore, ARM1156T2F-S, ARM1176TZF-S and Cortex-R4F. So exactly what this 'Multicore Cortex-A9 Tile' is... Acked-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

lcd_device_register may return ERR_PTR, so a check is added for this value before the dereference. All of the other changes reorganize the error handling code in this function to avoid duplicating all of it in the added case. In the original code, in one case, the global variable fb_buffer was set to NULL in error code that appears after this variable is initialized. This is done now in all error handling code that has this property. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r@ identifier f; @@ f(...) { ... return ERR_PTR(...); } @@ identifier r.f, fld; expression x; statement S1,S2; @@ x = f(...) ... when != IS_ERR(x) ( if (IS_ERR(x) ||...)
