| | | | | | | | | | | | | | | | | | | | | | | | | | btrfs assigns this bdi to all inodes on that file system, so make sure it's registered. This isn't really important now, but will be when we put dirty inodes there. Even now, we miss the stats when the bdi isn't visible. Also fixes failure to check bdi_init() return value, and bad inherit of ->capabilities flags from the default bdi.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for caching, to reduce FLASH wear when writing using small blocksizes. As we also don't care anymore about heads and tails in case of partial writes, this greatly simplifies the code for handling writes. Note: We don't bother caching reads smaller than the FLASH chunk size (256 KiB).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the FLASH database is updated by the kernel using file operations, meant for userspace only. While this works for us because copy_{from,to}_user() on powerpc can handle kernel pointers, this is unportable and a bad example.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the near future, the driver core is going to not allow direct access to the driver_data pointer in struct device.

| * | lib: Provide generic atomic64_t implementationPaul Mackerras2009-06-154-0/+225
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * | powerpc: Add compiler memory barrier to mtmsr macroPaul Mackerras2009-06-152-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * | powerpc: Don't do generic calibrate_delay()Benjamin Herrenschmidt2009-06-152-4/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Benjamin Herrenschmidt <benh@kernel.crashing.org>
| * | powerpc/install: Bail with error code on error in install scriptGrant Likely2009-06-151-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | If anything goes wrong when copying images into the install path, then the install script should exit with an error code so that 'make' knows about it and tells the user.
