The event numbering changed between revision r0 and r1 of the CCI PMU. Expose this to userspace to allow tooling to handle the differences in event numbers. Suggested-by:

The driver queries the CCI IP revision to distinguish between r0 and r1 scheme for event numbers and currently supports upto version r1p2. To minimise code churn every time there's a new version of the IP, assume that event numbering doesn't change for revisions > r1p0 (which is the case). The driver will still need an update for future revisions that change the event numbers. Signed-off-by:

Ivan Khoronzhuk authored
The problem that the set timings code contains the call of Davinci platform function davinci_aemif_setup_timing() which is not accessible if kernel is built for another platform like Keystone. The Keysone platform is going to use TI AEMIF driver. If TI AEMIF is used we don't need to set timings and bus width. It is done by AEMIF driver. To get rid of davinci-nand driver dependency on aemif platform code we moved aemif code to davinci platform. The platform AEMIF code (aemif.c) has to be removed once Davinci will be converted to DT and use ti-aemif.c driver. Acked-by:

Using the added infrastructure for handling SoC differences, this commit adds support for the watchdog controller available in Armada 370 and Armada XP SoCs. Also, and because the AXP clock initialization uses of_clk_get_by_name, this commit changes the orion clock initialization to use clk_get() and adds a proper clk_put() on the common exit/error paths.

After adding the IRQ request, the BRIDGE_CAUSE bit should be cleared by the bridge interrupt controller. There's no longer a need to do it in the watchdog driver, so we can simply remove it. Reviewed-by:

In order to support other SoC, it's required to distinguish the 'control' timer register, from the 'rstout' register that enables system reset on watchdog expiration. To prevent a compatibility break, this commit adds a fallback to a hardcoded RSTOUT address. Reviewed-by:

Ezequiel Garcia authored
DT-enabled plaforms, where the irqchip driver for the brigde interrupt controller is available, can handle the watchdog IRQ properly. Therefore, request the interrupt and add a dummy handler that merely calls panic(). This is done in order to have an initial 'ack' of the interruption, which clears the watchdog state. Furthermore, since some platforms don't have such IRQ, this commit makes the interrupt specification optional. Tested-by:

Ezequiel Garcia authored
Having the watchdog initially fully stopped is important to avoid any spurious watchdog triggers, in case the registers are not in its reset state. If the watchdog rstout is enabled and the watchdog counter running, this initial stop is not performed, to comply with the 'nowayout' parameter. Reviewed-by:

These are not used anywhere so it's safe to remove them. Reviewed-by:

Since the timer control register is shared with the clocksource driver, use the recently introduced atomic_io_clear_set() to access such register. Given the watchdog core already provides serialization for all the watchdog ops, this commit allows to remove the spinlock entirely. Reviewed-by:

When FS-Cache allocates an object, the following sequence of events can occur: -->fscache_alloc_object() -->cachefiles_alloc_object() [via cache->ops->alloc_object] <--[returns new object] -->fscache_attach_object() <--[failed] -->cachefiles_put_object() [via cache->ops->put_object] -->fscache_object_destroy() -->fscache_objlist_remove() -->rb_erase() to remove the object from fscache_object_list. resulting in a crash in the rbtree code. The problem is that the object is only added to fscache_object_list on the success path of fscache_attach_object() where it calls fscache_objlist_add(). So if fscache_attach_object() fails, the object won't have been added to the objlist rbtree. We do, however, unconditionally try to remove the object from the tree.

This has been this way for years, and every time I stumble across it I lose my lunch. After coming across it for the nth time in the Coverity results, I had to overcome the bystander effect and do something about it. This ignores the 79 column limit in favor of making it look like C instead of gibberish. The correct thing to do here would be to lose some of the indentation by breaking this function up into several smaller ones. I might do that at some point if I have the stomach to look at this again. (Also some of those overlong ternary operations would likely be more readable as regular if's) Signed-off-by:

If directory is fragmented, readdir() read its dirfrags one by one. After reading all dirfrags, the corresponding dentries are sorted in (frag_t, off) order in the dcache. If dentries of a directory are all cached, __dcache_readdir() can use the cached dentries to satisfy readdir syscall. But when checking if a given dentry is after the position of readdir, __dcache_readdir() compares numerical value of frag_t directly. This is wrong, it should use ceph_frag_compare().
