2014-04-07Kconfig: rename HAS_IOPORT to HAS_IOPORT_MAPUwe Kleine-König1-6/+6
If the renamed symbol is defined lib/iomap.c implements ioport_map and ioport_unmap and currently (nearly) all platforms define the port accessor functions outb/inb and friend unconditionally. So HAS_IOPORT_MAP is the better name for this. Consequently NO_IOPORT is renamed to NO_IOPORT_MAP. The motivation for this change is to reintroduce a symbol HAS_IOPORT that signals if outb/int et al are available. I will address that at least one merge window later though to keep surprises to a minimum and catch new introductions of (HAS|NO)_IOPORT. The changes in this commit were done using: $ git grep -l -E '(NO|HAS)_IOPORT' | xargs perl -p -i -e 's/\b((?:CONFIG_)?(?:NO|HAS)_IOPORT)\b/$1_MAP/' Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2014-03-27ARM: moxart: fix CPU selectionArnd Bergmann1-0/+6
Moxart uses an FA526 CPU core, which is ARMv4 based, not ARMv4T. Before moxart, we had no CONFIG_MULTI_V4 option, since no ARMv4 platform was enabled for multiplatform. This now adds the missing option, which will give us slightly more efficient code on pure moxart kernels, because we can build a pure FA526 kernel now rather than a combined FA526+ARM920T kernel that we used to.

With noMMU, CONFIG_PAGE_OFFSET was not being set correctly. As there's no MMU, PAGE_OFFSET should be equal to PHYS_OFFSET in all cases. This commit makes that explicit. Since we do this, we don't need to mess around in asm/memory.h with ifdefs to sort this out, so let's get rid of that, and there's no point offering the "Memory split" option for noMMU as that's meaningless there.

next/cleanup Merge "efm32 cleanups for next" from Uwe Kleine-König Just three simple cleanups for efm32 removing two now unused files and a superflous select by ARCH_EFM32. As these cleanups have dependencies on both v3.14-rc1 and my timex.h cleanup (which is based on v3.13-rc1) this pull request also included a merge of my cleanup tag which is already in armsoc/next/cleanup. * tag 'efm32-next' of git://git.pengutronix.de/git/ukl/linux: ARM: efm32: drop unused file <mach/timex.h> ARM: efm32: drop selecting CLKSRC_MMIO ARM: efm32: drop unused file entry-macro.S Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2014-02-24ARM: efm32: drop selecting CLKSRC_MMIOUwe Kleine-König1-3/+0
CLKSRC_MMIO is needed on efm32 because the clocksource driver (CLKSRC_EFM32) uses clocksource_mmio_init() and clocksource_mmio_readl_up(). Since commit 09ca27579ee5 (clocksource: time-efm32: Select CLKSRC_MMIO) CLKSRC_EFM32 does the necessary select itself and ARCH_EFM32 doesn't need to select it explicitly any more.

2014-01-30xen: swiotlb: handle sizeof(dma_addr_t) != sizeof(phys_addr_t)Ian Campbell1-0/+1
The use of phys_to_machine and machine_to_phys in the phys<=>bus conversions causes us to lose the top bits of the DMA address if the size of a DMA address is not the same as the size of the phyiscal address. This can happen in practice on ARM where foreign pages can be above 4GB even though the local kernel does not have LPAE page tables enabled (which is totally reasonable if the guest does not itself have >4GB of RAM). In this case the kernel still maps the foreign pages at a phys addr below 4G (as it must) but the resulting DMA address (returned by the grant map operation) is much higher. This is analogous to a hardware device which has its view of RAM mapped up high for some reason. This patch makes I/O to foreign pages (specifically blkif) work on 32-bit ARM systems with more than 4GB of RAM.
