Now that the generic code has dma_map_ops set, instead of having a messy ifdef & if block in the base dma_get_required_mask hook push the computation into the dma ops. If the ops fails to set the get_required_mask hook default to the width of dma_addr_t. This also corrects ibmbus ibmebus_dma_supported to require a 64 bit mask. I doubt anything is checking or setting the dma mask on that bus.

If an architecture sets ARCH_HAS_DMA_GET_REQUIRED_MASK and has settable dma_map_ops, the required mask may change by the ops implementation. For example, a system that always has an mmu inline may only require 32 bits while a swiotlb would desire bits to cover all of memory. Therefore add the field if the architecture does not use the generic definition of dma_get_required_mask. The first use will by by powerpc. Note that this does add some dependency on the order in which files are visible here.

由 Milton Miller 提交于
The hook dma_get_required_mask is supposed to return the mask required by the platform to operate efficently. The generic version of dma_get_required_mask in driver/base/platform.c returns a mask based only on max_pfn. However, this is likely too big for iommu systems and could be too small for platforms that require a dma offset or have a secondary window at a high offset. Override the default, provide a hook in ppc_md used by pseries lpar and cell, and provide the default answer based on memblock_end_of_DRAM(), with hooks for get_dma_offset, and provide an implementation for iommu that looks at the defined table size. Coverting from the end address to the required bit mask is based on the generic implementation. The need for this was discovered when the qla2xxx driver switched to 64 bit dma then reverted to 32 bit when dma_get_required_mask said 32 bits was sufficient.

If there are no builtin users of find_next_bit_le() and find_next_zero_bit_le(), these functions are not present in the kernel image, causing m68k allmodconfig to fail with: ERROR: "find_next_zero_bit_le" [fs/ufs/ufs.ko] undefined! ERROR: "find_next_bit_le" [fs/udf/udf.ko] undefined! ... This started to happen after commit 171d809d ("m68k: merge mmu and non-mmu bitops.h"), as m68k had its own inline versions before. commit 63e424c8 ("arch: remove CONFIG_GENERIC_FIND_{NEXT_BIT, BIT_LE, LAST_BIT}") added find_last_bit.o to obj-y (so it's always included), but find_next_bit.o to lib-y (so it gets removed by the linker if there are no builtin users).

On Sun4d systems running in SMP mode, IRQ 14 is used for timer interrupts and has a specialized interrupt handler. IPI is currently set to use IRQ 14 as well, which causes it to trigger the timer interrupt handler, and not the IPI interrupt handler. The IPI interrupt is therefore changed to IRQ 13, which is the highest normally handled interrupt. This IRQ is also used for SBUS interrupts, however there is nothing in the IPI/SBUS interrupt handlers that indicate that they will not handle sharing the interrupt. (IRQ 13 is indicated as audio interrupt, which is unlikely to be found in a sun4d system) Signed-off-by: NKjetil Oftedal <oftedal@gmail.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

This patch removes support for the SGX interrupt source in the sh7372 INTCS controller. The SGX hardware block included in sh7372 is already hooked up to the ARM Cortex-A8 core using the INTCA controller, so SGX users are encouraged to make use of that interrupt source instead. Removing support for the SGX interrupt source in INTCS simplifies the sh7372 power management code by allowing us to assume that only INTCA needs to be powered on to operate the SGX hardware. If the INTCS interrupt source would be kept then the kernel would be forced to deal with additional dependencies that does not follow the regular power domain hiearachy. With this patch in place we can safely power down INTCS while the SGX is operating. Signed-off-by: NMagnus Damm <damm@opensource.se> Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

sh-sci.c sets hardware up and then let the HW do all flow controls. There is no software code, nor needs to get/set real CTS signal. But, when turning CRTSCTS on through termios, uart_set_termios() in serial_core.c checks CTS, and stops TX if it is inactive at the moment. Because sci_get_mctrl() returns a fixed value DTR|RTS|DSR but CTS, the sequence open -> set CRTSCTS -> write hit the case and stop working, no more outputs.
