In the near future, the driver core is going to not allow direct access to the driver_data pointer in struct device. Instead, the functions dev_get_drvdata() and dev_set_drvdata() should be used. These functions have been around since the beginning, so are backwards compatible with all older kernel versions. [Geert: Use ps3_system_bus_[gs]et_driver_data() for ps3_system_bus_device] Signed-off-by:

Remove the mutex serializing access to the cache. Instead, queue up new requests on a bio_list if the driver is busy. This improves sequential write performance by ca. 2%. Signed-off-by:

Introduce bio_list_peek(), to obtain a pointer to the first bio on the bio_list without actually removing it from the list. This is needed when you want to serialize based on the list being empty or not. Signed-off-by:

This makes 32-bit powerpc use the generic atomic64_t implementation. Signed-off-by:

Paul Mackerras authored
Many processor architectures have no 64-bit atomic instructions, but we need atomic64_t in order to support the perf_counter subsystem. This adds an implementation of 64-bit atomic operations using hashed spinlocks to provide atomicity. For each atomic operation, the address of the atomic64_t variable is hashed to an index into an array of 16 spinlocks. That spinlock is taken (with interrupts disabled) around the operation, which can then be coded non-atomically within the lock. On UP, all the spinlock manipulation goes away and we simply disable interrupts around each operation. In fact gcc eliminates the whole atomic64_lock variable as well. Signed-off-by:

On 32-bit non-Book E, local_irq_restore() turns into just mtmsr(), which doesn't currently have a compiler memory barrier. This means that accesses to memory inside a local_irq_save/restore section, or a spin_lock_irqsave/spin_unlock_irqrestore section on UP, can be reordered by the compiler to occur outside that section. To fix this, this adds a compiler memory barrier to mtmsr for both 32-bit and 64-bit. Having a compiler memory barrier in mtmsr makes sense because it will almost always be changing something about the context in which memory accesses are done, so in general we don't want memory accesses getting moved from one side of an mtmsr to the other. With the barrier in mtmsr(), some of the explicit barriers in hw_irq.h are now redundant, so this removes them. Signed-off-by:

signal_vsp_instruction() is currently only used if CONFIG_PROC_FS is enabled. However logically it has nothing to do with PROC_FS, so rather than making it depend on that mark it as maybe unused. Signed-off-by:

If CONFIG_BLK_DEV_INITRD is unset dt_prop_u64() is unused, which causes a warning. We don't really want to tie the definition to BLK_DEV_INITRD, so mark it as maybe unused. Signed-off-by:

Commit 28794d34 ("powerpc/kconfig: Kill PPC_MULTIPLATFORM"), added CONFIG_PPC_OF_BOOT_TRAMPOLINE to control the buliding of prom_init.o However the Makefile still unconditionally builds prom_init_check, the script that checks prom_init.o for symbol usage, and so in turn prom_init.o is still always being built. (it's not linked though) So surround all the prom_init_check logic with an ifeq block testing if CONFIG_PPC_OF_BOOT_TRAMPOLINE is set. Signed-off-by:

Currently we are wasting time calling the generic calibrate_delay() function. We don't need it since our implementation of __delay() is based on the CPU timebase. So instead, we use our own small implementation that initializes loops_per_jiffy to something sensible to make the few users like spinlock debug be happy Signed-off-by: -

In addition to KT_DEAD which has limited support for diacriticals, there is KT_DEAD2 that can support 256 criticals, so let's advertise it in <linux/keyboard.h>. This lets userland know abut the drivers/char/keyboard.c function k_dead2, which supports more than the few trivial ones that k_dead supports. Signed-off-by:
