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.

由 Davidlohr Bueso 提交于
The arch_mutex_cpu_relax() function, introduced by 34b133f8, 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.

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.

We perform a clean up of the Kbuid files in each architecture. We order the files in each Kbuild in alphabetical order by running the below script. for i in arch/*/include/asm/Kbuild do cat $i | gawk '/^generic-y/ { i = 3; do { for (; i <= NF; i++) { if ($i == "\\") { getline; i = 1; continue; } if ($i != "") hdr[$i] = $i; } break; } while (1); next; } // { print $0; } END { n = asort(hdr); for (i = 1; i <= n; i++) print "generic-y += " hdr[i]; }' > ${i}.sorted; mv ${i}.sorted $i; done Signed-off-by: NTim Chen <tim.c.chen@linux.intel.com> Cc: Arnd Bergmann <arnd@arndb.de> Cc: Matthew R Wilcox <matthew.r.wilcox@intel.com> Cc: AswinChandramouleeswaran <aswin@hp.com> Cc: Dave Hansen <dave.hansen@intel.com> Cc: "Paul E.McKenney" <paulmck@linux.vnet.ibm.com> Cc: Scott J Norton <scott.norton@hp.com> Cc: Will Deacon <will.deacon@arm.com> Cc: "Figo.zhang" <figo1802@gmail.com> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Rik van Riel <riel@redhat.com> Cc: Waiman Long <waiman.long@hp.com> Cc: Peter Hurley <peter@hurleysoftware.com> Cc: Andrea Arcangeli <aarcange@redhat.com> Cc: Tim Chen <tim.c.chen@linux.intel.com> Cc: Alex Shi <alex.shi@linaro.org> Cc: Raghavendra K T <raghavendra.kt@linux.vnet.ibm.com> Cc: Andi Kleen <andi@firstfloor.org> Cc: George Spelvin <linux@horizon.com> Cc: MichelLespinasse <walken@google.com> Cc: Ingo Molnar <mingo@elte.hu> Cc: "H.

Fengguang Wu's kbuild test robot reported the following new m68k warnings: In file included from drivers/nubus/nubus.c:22:0: >> arch/m68k/include/asm/mac_via.h:262:47: warning: 'struct irq_desc' declared inside parameter list [enabled by default] >> arch/m68k/include/asm/mac_via.h:262:47: warning: its scope is only this definition or declaration, which is probably not what you want [enabled by default] Caused by the reworking of the generic local_bh{dis,en}able() code. To fix it, forward declare 'struct irq_desc'.

We're going to be adding a few new barrier primitives, and in order to avoid endless duplication make more agressive use of asm-generic/barrier.h. Change the asm-generic/barrier.h such that it allows partial barrier definitions and fills out the rest with defaults. There are a few architectures (m32r, m68k) that could probably do away with their barrier.h file entirely but are kept for now due to their unconventional nop() implementation.

Rename RTC_PORT() to ATARI_RTC_PORT(), as the rtc-cmos RTC driver uses the presence of this macro to enable support for the second NVRAM bank, which Atari doesn't have ("Unable to handle kernel access at virtual address 00ff8965"). Signed-off-by: NGeert Uytterhoeven <geert@linux-m68k.org>

Add optional support to export the bootinfo used to boot the kernel in a "bootinfo" file in procfs. This is useful with kexec. This is based on the similar feature for ATAGS on ARM. Signed-off-by: NGeert Uytterhoeven <geert@linux-m68k.org>

On m68k, get_cycles() (the default implementation for random_get_entropy()) always returns zero, providing no entropy for the random driver. Add a hook where platforms can provide their own implementation, and wire it up in the infrastructure provided by commit 61875f30 ("random: allow architectures to optionally define random_get_entropy()").
