2015-02-03m68knommu: fix irq handler types in 68360/commproc.cGreg Ungerer1-1/+1
Compilation of arch/m68k/68360/commproc.c fails with the following errors: arch/m68k/68360/commproc.c:75:1: error: function declaration isn’t a prototype arch/m68k/68360/commproc.c:211:1: error: function declaration isn’t a prototype arch/m68k/68360/commproc.c: In function ‘cpm_install_handler’: arch/m68k/68360/commproc.c:214:2: warning: passing argument 2 of ‘request_irq’ from incompatible pointer type include/linux/interrupt.h:128:1: note: expected ‘irq_handler_t’ but argument is of type ‘void (*)()’ It should be using the proper irq hander type, irq_handler_t.

2015-02-03m68k: remove check for CONFIG_BSEIPPaul Bolle1-22/+0
There used to be a Kconfig symbol BSEIP. It was PPC specific and was removed in v2.6.27. So the check for CONFIG_BSEIP can be removed. This means a few defines will be removed. None of the macros involved are used, so no one should care. Signed-off-by: Paul Bolle <pebolle@tiscali.nl> Signed-off-by: Greg Ungerer <gerg@uclinux.org>
2015-01-15m68k/atari: Remove obsolete IRQ_TYPE_*Geert Uytterhoeven1-5/+0
IRQ_TYPE_SLOW, IRQ_TYPE_FAST, and IRQ_TYPE_PRIO are no longer used by the Atari platform interrupt code since commit 734085651c9b80aa ("[PATCH] m68k: convert atari irq code") in v2.6.18-rc1, so drop them. Note that their values have been reused for different purposes (IRQ_TYPE_NONE, IRQ_TYPE_EDGE_RISING, and IRQ_TYPE_EDGE_FALLING) since commit 6a6de9ef5850d063 ("[PATCH] genirq: core") in v2.6.18-rc1.

2015-01-11m68k/mac: Fix scsi_type for Mac LC and similar modelsFinn Thain1-1/+1
Designing Cards and Drivers for the Macintosh Family, 3rd ed. on page 310 says that the I/O address space for the Mac LC is $50F0 0000 - $50FF FFFF. The developer notes for the Classic II, LC III and IIvx/IIvi give the same I/O address space. That means I've assigned the wrong platform resources to those Mac models. Fix the scsi_type initialization for the affected models, to restore the SCSI base address to its value prior to Linux 3.18. Also rename MAC_SCSI_CCL as MAC_SCSI_LC for the sake of correct chronology. Signed-off-by: Finn Thain <fthain@telegraphics.com.au> Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>

Pull asm-generic asm/io.h rewrite from Arnd Bergmann: "While there normally is no reason to have a pull request for asm-generic but have all changes get merged through whichever tree needs them, I do have a series for 3.19. There are two sets of patches that change significant portions of asm/io.h, and this branch contains both in order to resolve the conflicts: - Will Deacon has done a set of patches to ensure that all architectures define {read,write}{b,w,l,q}_relaxed() functions or get them by including asm-generic/io.h. These functions are commonly used on ARM specific drivers to avoid expensive L2 cache synchronization implied by the normal {read,write}{b,w,l,q}, but we need to define them on all architectures in order to share the drivers across architectures and to enable CONFIG_COMPILE_TEST configurations for them - Thierry Reding has done an unrelated set of patches that extends the asm-generic/io.h file to the degree necessary to make it useful on ARM64 and potentially other architectures" * tag 'asm-generic-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic: (29 commits) ARM64: use GENERIC_PCI_IOMAP sparc: io: remove duplicate relaxed accessors on sparc32 ARM: sa11x0: Use void __iomem * in MMIO accessors arm64: Use include/asm-generic/io.h ARM: Use include/asm-generic/io.h asm-generic/io.h: Implement generic {read,write}s*() asm-generic/io.h: Reconcile I/O accessor overrides /dev/mem: Use more consistent data types Change xlate_dev_{kmem,mem}_ptr() prototypes ARM: ixp4xx: Properly override I/O accessors ARM: ixp4xx: Fix build with IXP4XX_INDIRECT_PCI ARM: ebsa110: Properly override I/O accessors ARC: Remove redundant PCI_IOBASE declaration documentation: memory-barriers: clarify relaxed io accessor semantics x86: io: implement dummy relaxed accessor macros for writes tile: io: implement dummy relaxed accessor macros for writes sparc: io: implement dummy relaxed accessor macros for writes powerpc: io: implement dummy relaxed accessor macros for writes parisc: io: implement dummy relaxed accessor macros for writes mn10300: io: implement dummy relaxed accessor macros for writes ...
2014-11-20atari_scsi: Fix atari_scsi deadlocks on FalconFinn Thain1-2/+2
Don't disable irqs when waiting for the ST DMA "lock"; its release may require an interrupt. Introduce stdma_try_lock() for use in soft irq context. atari_scsi now tells the SCSI mid-layer to defer queueing a command if the ST DMA lock is not available, as per Michael's patch: http://marc.info/?l=linux-m68k&m=139095335824863&w=2 The falcon_got_lock variable is race prone: we can't disable IRQs while waiting to acquire the lock, so after acquiring it there must be some interval during which falcon_got_lock remains false. Introduce stdma_is_locked_by() to replace falcon_got_lock. The falcon_got_lock tests in the EH handlers are incorrect these days. It can happen that an EH handler is called after a command completes normally. Remove these checks along with falcon_got_lock. Also remove the complicated and racy fairness wait queues. If fairness is an issue (when SCSI competes with IDE for the ST DMA interrupt), the solution is likely to be a lower value for host->can_queue.

write{b,w,l}_relaxed are implemented by some architectures in order to permit memory-mapped I/O accesses with weaker barrier semantics than the non-relaxed variants. This patch adds dummy macros for the write accessors to m68k, in the same vein as the dummy definitions for the relaxed read accessors. Additionally, the existing relaxed read accessors are moved into asm/io.h, so that they can be used by m68k targets with an MMU.

2014-07-17arch, locking: Ciao arch_mutex_cpu_relax()Davidlohr Bueso1-0/+1
The arch_mutex_cpu_relax() function, introduced by 34b133f, is hacky and ugly. It was added a few years ago to address the fact that common cpu_relax() calls include yielding on s390, and thus impact the optimistic spinning functionality of mutexes. Nowadays we use this function well beyond mutexes: rwsem, qrwlock, mcs and lockref. Since the macro that defines the call is in the mutex header, any users must include mutex.h and the naming is misleading as well. This patch (i) renames the call to cpu_relax_lowlatency ("relax, but only if you can do it with very low latency") and (ii) defines it in each arch's asm/processor.h local header, just like for regular cpu_relax functions. On all archs, except s390, cpu_relax_lowlatency is simply cpu_relax, and thus we can take it out of mutex.h. While this can seem redundant, I believe it is a good choice as it allows us to move out arch specific logic from generic locking primitives and enables future(?) archs to transparently define it, similarly to System Z.

2014-05-26m68k/atari - stram: alloc ST-RAM pool even if kernel not in ST-RAMMichael Schmitz1-0/+2
With the kernel loaded to FastRAM (TT-RAM), none of the ST-RAM address range is mapped by init_mem, and ST-RAM is not accessible through the normal allocation pathways as a result. Implement ST-RAM pool allocation to be based on physical addresses always (it already was when the kernel was loaded in ST-RAM). Return kernel virtual addresses as per normal. The current test for the kernel residing in ST-RAM always returns true. Use the bootinfo memory chunk order instead - with the kernel in FastRAM, ST-RAM (phys. 0x0) is not the first chunk. In case the kernel is running from FastRAM, delay mapping of ST-RAM pool until after mem_init. Provide helper functions for those users of ST-RAM that need to be aware of the backing physical addresses. Kudos to Geert for his hints on getting this started.
