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: NBenjamin Herrenschmidt <benh@kernel.crashing.org>

This provides a reliable way for asm-generic/types.h and other files to find out if it is running on a 32 or 64 bit platform. We cannot use CONFIG_64BIT for this in headers that are included from user space because CONFIG symbols are not available there. We also cannot do it inside of asm/types.h because some headers need the word size but cannot include types.h. The solution is to introduce a new header <asm/bitsperlong.h> that defines both __BITS_PER_LONG for user space and BITS_PER_LONG for usage in the kernel. The asm-generic version falls back to 32 bit unless the architecture overrides it, which I did for all 64 bit platforms.

This patch includes the basic infrastructure to use swiotlb bounce buffering on 32-bit powerpc. It is not yet enabled on any platforms. Probably the most interesting bit is the addition of addr_needs_map to dma_ops - we need this as a dma_op because the decision of whether or not an addr can be mapped by a device is device-specific.

Currently, load_up_altivec and give_up_altivec are duplicated in 32-bit and 64-bit. This creates a common implementation that is moved away from head_32.S, head_64.S and misc_64.S and into vector.S, using the same macros we already use for our common implementation of load_up_fpu. I also moved the VSX code over to vector.S though in that case I didn't make it build on 32-bit (yet). Signed-off-by: NBenjamin Herrenschmidt <benh@kernel.crashing.org>

For some obscure reason, we only set init_bootmem_done after initializing bootmem when NUMA isn't enabled. We even document this next to the declaration of that global in system.h which of course I didn't read before I had to debug why some WIP code wasn't working properly... This patch changes it so that we always set it after bootmem is initialized which should have always been the case... go figure ! Signed-off-by: NBenjamin Herrenschmidt <benh@kernel.crashing.org>

The MMU context_lock can be taken from switch_mm() while the rq->lock is held. The rq->lock can also be taken from interrupts, thus if we get interrupted in destroy_context() with the context lock held and that interrupt tries to take the rq->lock, there's a possible deadlock scenario with another CPU having the rq->lock and calling switch_mm() which takes our context lock. The fix is to always ensure interrupts are off when taking our context lock. The switch_mm() path is already good so this fixes the destroy_context() path. While at it, turn the context lock into a new style spinlock. Signed-off-by: NBenjamin Herrenschmidt <benh@kernel.crashing.org>

This patch fixes a couple of issues that can happen as a result of steal_context() dropping the context_lock when all possible PIDs are ineligible for stealing (hopefully an extremely hard to hit occurence). This case exposes the possibility of a stale context_mm[] entry to be seen since destroy_context() doesn't clear it and the free map isn't re-tested. It also means steal_context() will not notice a context freed while the lock was help, thus possibly trying to steal a context when a free one was available. This fixes it by always returning to the caller from steal_context when it dropped the lock with a return value that causes the caller to re-samble the number of free contexts, along with properly clearing the context_mm[] array for destroyed contexts.
