ARM: Convert to platform remove callback returning void The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

ARM: sa1100/assabet: move dmabounce hack to ohci driver The sa1111 platform is one of the two remaining users of the old Arm specific "dmabounce" code, which is an earlier implementation of the generic swiotlb. Linus Walleij submitted a patch that removes dmabounce support from the ixp4xx, and I had a look at the other user, which is the sa1111 companion chip. Looking at how dmabounce is used, I could narrow it down to one driver one three machines: - dmabounce is only initialized on assabet/neponset, jornada720 and badge4, which are the platforms that have an sa1111 and support DMA on it. - All three of these suffer from "erratum #7" that requires only doing DMA to half the memory sections based on one of the address lines, in addition, the neponset also can't DMA to the RAM that is connected to sa1111 itself. - the pxa lubbock machine also has sa1111, but does not support DMA on it and does not set dmabounce. - only the OHCI and audio devices on sa1111 support DMA, but as there is no audio driver for this hardware, only OHCI remains. In the OHCI code, I noticed that two other platforms already have a local bounce buffer support in the form of the "local_mem" allocator. Specifically, TMIO and SM501 use this on a few other ARM boards with 16KB or 128KB of local SRAM that can be accessed from the OHCI and from the CPU. While this is not the same problem as on sa1111, I could not find a reason why we can't re-use the existing implementation but replace the physical SRAM address mapping with a locally allocated DMA buffer. There are two main downsides: - rather than using a dynamically sized pool, this buffer needs to be allocated at probe time using a fixed size. Without having any idea of what it should be, I picked a size of 64KB, which is between what the other two OHCI front-ends use in their SRAM. If anyone has a better idea what that size is reasonable, this can be trivially changed. - Previously, only USB transfers to unaddressable memory needed to go through the bounce buffer, now all of them do, which may impact runtime performance for USB endpoints that do a lot of transfers. On the upside, the local_mem support uses write-combining buffers, which should be a bit faster for transfers to the device compared to normal uncached coherent memory as used in dmabounce.

ARM: pxa: split up mach/hardware.h The mach/hardware.h is included in lots of places, and it provides three different things on pxa: - the cpu_is_pxa* macros - an indirect inclusion of mach/addr-map.h - the __REG() and io_pv2() helper macros Split it up into separate <linux/soc/pxa/cpu.h> and mach/pxa-regs.h headers, then change all the files that use mach/hardware.h to include the exact set of those three headers that they actually need, allowing for further more targeted cleanup. linux/soc/pxa/cpu.h can remain permanently exported and is now in a global location along with similar headers. pxa-regs.h and addr-map.h are only used in a very small number of drivers now and can be moved to arch/arm/mach-pxa/ directly when those drivers are to pass the necessary data as resources.

bus: Make remove callback return void The driver core ignores the return value of this callback because there is only little it can do when a device disappears. This is the final bit of a long lasting cleanup quest where several buses were converted to also return void from their remove callback. Additionally some resource leaks were fixed that were caused by drivers returning an error code in the expectation that the driver won't go away. With struct bus_type::remove returning void it's prevented that newly implemented buses return an ignored error code and so don't anticipate wrong expectations for driver authors.

ARM: sa1111: fix pcmcia suspend/resume SA1111 PCMCIA was broken when PCMCIA switched to using dev_pm_ops for the PCMCIA socket class. PCMCIA used to handle suspend/resume via the socket hosting device, which happened at normal device suspend/resume time. However, the referenced commit changed this: much of the resume now happens much earlier, in the noirq resume handler of dev_pm_ops. However, on SA1111, the PCMCIA device is not accessible as the SA1111 has not been resumed at _noirq time. It's slightly worse than that, because the SA1111 has already been put to sleep at _noirq time, so suspend doesn't work properly. Fix this by converting the core SA1111 code to use dev_pm_ops as well, and performing its own suspend/resume at noirq time. This fixes these errors in the kernel log: pcmcia_socket pcmcia_socket0: time out after reset pcmcia_socket pcmcia_socket1: time out after reset and the resulting lack of PCMCIA cards after a S2RAM cycle.

ARM: kill off set_irq_flags usage set_irq_flags is ARM specific with custom flags which have genirq equivalents. Convert drivers to use the genirq interfaces directly, so we can kill off set_irq_flags. The translation of flags is as follows: IRQF_VALID -> !IRQ_NOREQUEST IRQF_PROBE -> !IRQ_NOPROBE IRQF_NOAUTOEN -> IRQ_NOAUTOEN For IRQs managed by an irqdomain, the irqdomain core code handles clearing and setting IRQ_NOREQUEST already, so there is no need to do this in .map() functions and we can simply remove the set_irq_flags calls. Some users also modify IRQ_NOPROBE and this has been maintained although it is not clear that is really needed. There appears to be a great deal of blind copy and paste of this code.

ARM: sa1111: finish "allow cascaded IRQs to be used by platforms" Commit 19851c58e680 (sa1111: allow cascaded IRQs to be used by platforms) moved the IRQ definitions to the .c file, and added an irq_base member to the private data structure. The inerrupt demultiplexer uses irq_base, but the interrupt setup code does not. Also, although the commit adds a private data structure to pass this data, it isn't even referenced, resulting in irq_base being zero. We also copied the IRQ numbers from the device info array into the actual devices, resulting in wrong interrupt numbers passed to the sub-devices. The net effect of this is that we always overwrite IRQs 0-54, even if they are allocated elsewhere in the system. Add the code necessary to setup the private irq_base, and use it in the IRQ setup code. Make the SA-1111 probe fail with -EINVAL if there is no platform data provided.

[ARM] Remove needless linux/ptrace.h includes Lots of places in arch/arm were needlessly including linux/ptrace.h, resumably because we used to pass a struct pt_regs to interrupt handlers. Now that we don't, all these ptrace.h includes are redundant. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

[ARM] 3739/1: genirq updates: irq_chip, add and use irq_chip.name Patch from David Brownell ARM genirq cleanups/updates: - Start switching platforms to newer APIs * use "irq_chip" name, not "irqchip" * providing irq_chip.name - Show irq_chip.name in /proc/interrupts, like on x86. This update a bit more than half of the ARM code. The irq_chip.name values were chosen to match docs (if I have them) or be otherwise obvious ("FPGA", "CPLD", or matching the code).

[PATCH] DRIVER MODEL: Get rid of the obsolete tri-level suspend/resume callbacks In PM v1, all devices were called at SUSPEND_DISABLE level. Then all devices were called at SUSPEND_SAVE_STATE level, and finally SUSPEND_POWER_DOWN level. However, with PM v2, to maintain compatibility for platform devices, I arranged for the PM v2 suspend/resume callbacks to call the old PM v1 suspend/resume callbacks three times with each level in order so that existing drivers continued to work. Since this is obsolete infrastructure which is no longer necessary, we can remove it. Here's an (untested) patch to do exactly that.

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
