2012-07-17m68k: common PCI support definitions and codeGreg Ungerer
Basic set of definitions and support code required to turn on CONFIG_PCI for the m68k architecture. Nothing specific to any PCI implementation in any m68k class CPU hardware yet. Signed-off-by: Greg Ungerer <gerg@uclinux.org> Acked-by: Geert Uytterhoeven <geert@linux-m68k.org>
2012-07-17m68k: add support for DMA_BIDIRECTIONAL in dma support functionsGreg Ungerer
The dma cache support functions do not currently support the direction flag DMA_BIDIRECTIONAL. If a driver passes this direction to dma_map_single or friends you will get console output like this: dma_sync_single_for_device: unsupported dir 0 For example when using the Intel e100 ethernet driver on a ColdFire platform with PCI bus. You will get a stream of these messages coming out. Modify the dma cache support code adding support for DMA_BIDIRECTIONAL. It is actioned by doing a cache push operation.

2012-07-17m68k: fix ColdFire clear cache operationGreg Ungerer
The code for clearing (invalidating) the ColdFire cache is actually performing a push operation. Add functions to clear the cache, and fix cache_clear() to call the appropriate clear cache function. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
2012-07-15m68k: use simpler dma_alloc_coherent() for ColdFire CPUsGreg Ungerer
On all ColdFire platforms (whether MMU enabled or not) we want to use the simple page based dma_alloc_coherent. We don't want the virtual mapping version that is used on classic m68k setups. So modify the conditionals to use the existing simpler dma_alloc_coherent on all ColdFire and non-MMU builds. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
2012-07-15m68knommu: platform support for 8390 based ethernet used on some boardsGreg Ungerer

2012-07-15m68knommu: add definitions for the third interrupt controller on devices ↵Steven King
that don't have a third interrupt controller. Extending the interrupt controller code in intc-simr.c to support the third interrupt controller on the m5441x means we need to add defines (as 0) for the third interrupt controller on devices that don't have a third interrupt controller.

2012-07-15m68knommu: Add support for the Coldfire m5441x.Steven King
Add support for the Coldfire 5441x (54410/54415/54416/54417/54418). Currently we only support noMMU mode. It requires the PIT patch posted previously as it uses the PIT instead of the dma timer as a clock source so we can get all that GENERIC_CLOCKEVENTS goodness. It also adds some simple clk definitions and very simple minded power management. The gpio code is tweeked and some additional devices are added to devices.c. The Makefile uses -mv4e as apparently, the only difference a v4m (m5441x) and a v4e is the later has a FPU, which I don't think should matter to us in the kernel.

2012-07-15m68knommu: refactor Coldfire GPIO not to require GPIOLIB, eliminate ↵Steven King
mcf_gpio_chips. If we're not connecting external GPIO extenders via i2c or spi or whatever, we probably don't need GPIOLIB. If we provide an alternate implementation of the GPIOLIB functions to use when only on-chip GPIO is needed, we can change ARCH_REQUIRE_GPIOLIB to ARCH_WANTS_OPTIONAL_GPIOLIB so that GPIOLIB becomes optional. The downside is that in the GPIOLIB=n case, we lose all error checking done by gpiolib, ie multiply allocating the gpio, free'ing gpio etc., so that the only checking that can be done is if we reference a gpio on an external part. Targets that need the extra error checking can still select GPIOLIB=y. For the case where GPIOLIB=y, we can simplify the table of gpio chips to use a single chip, eliminating the tables of chips in the 5xxx.c files. The original motivation for the definition of multiple chips was to match the way many of the Coldfire variants defined their gpio as a spare array in memory. However, all this really gains us is some error checking when we request a gpio, gpiolib can check that it doesn't fall in one of the holes. If thats important, I think we can still come up with a better way of accomplishing that. Also in this patch is some general cleanup and reorganizing of the gpio header files (I'm sure I must have had a reason why I sometimes used a prefix of mcf_gpio and other times mcfgpio but for the life of me I can't think of it now).

2012-07-15m68k: use jbsr to call functions instead of bsrlGreg Ungerer
There is a few places that the m68k entry code uses the bsrl instruction to call other functions. That instruction is only supported on 68020 and higher CPU types.

2012-07-15m68k: use some direct calls to ret_from_exception in entry codeGreg Ungerer
The ret_from_excption code is referenced by its function name, or by a label set at the start of its code. The non-MMU code can share some of this code if we make direct calls to ret_from_exception instead of the associated label. The effected function paths are: buserr, trap and ret_from_fork. So change these to branch directly to ret_from_exception. Signed-off-by: Greg Ungerer <gerg@uclinux.org> Acked-by: Geert Uytterhoeven <geert@linux-m68k.org>

2012-07-13x86/vsyscall: allow seccomp filter in vsyscall=emulateWill Drewry
If a seccomp filter program is installed, older static binaries and distributions with older libc implementations (glibc 2.13 and earlier) that rely on vsyscall use will be terminated regardless of the filter program policy when executing time, gettimeofday, or getcpu. This is only the case when vsyscall emulation is in use (vsyscall=emulate is the default). This patch emulates system call entry inside a vsyscall=emulate by populating regs->ax and regs->orig_ax with the system call number prior to calling into seccomp such that all seccomp-dependencies function normally. Additionally, system call return behavior is emulated in line with other vsyscall entrypoints for the trace/trap cases.

2012-07-13block: fix infinite loop in __getblk_slowJeff Moyer
Commit 080399aaaf35 ("block: don't mark buffers beyond end of disk as mapped") exposed a bug in __getblk_slow that causes mount to hang as it loops infinitely waiting for a buffer that lies beyond the end of the disk to become uptodate. The problem was initially reported by Torsten Hilbrich here: https://lkml.org/lkml/2012/6/18/54 and also reported independently here: http://www.sysresccd.org/forums/viewtopic.php?f=13&t=4511 and then Richard W.M. Jones and Marcos Mello noted a few separate bugzillas also associated with the same issue. This patch has been confirmed to fix: https://bugzilla.redhat.com/show_bug.cgi?id=835019 The main problem is here, in __getblk_slow: for (;;) { struct buffer_head * bh; int ret; bh = __find_get_block(bdev, block, size); if (bh) return bh; ret = grow_buffers(bdev, block, size); if (ret < 0) return NULL; if (ret == 0) free_more_memory(); } __find_get_block does not find the block, since it will not be marked as mapped, and so grow_buffers is called to fill in the buffers for the associated page. I believe the for (;;) loop is there primarily to retry in the case of memory pressure keeping grow_buffers from succeeding. However, we also continue to loop for other cases, like the block lying beond the end of the disk. So, the fix I came up with is to only loop when grow_buffers fails due to memory allocation issues (return value of 0). The attached patch was tested by myself, Torsten, and Rich, and was found to resolve the problem in call cases.

2012-07-13ALSA: snd-usb: move calls to usb_set_interfaceDaniel Mack
The rework of the snd-usb endpoint logic moved the calls to snd_usb_set_interface() into the snd_usb_endpoint implemenation. This changed the order in which these calls are issued to the device, and thereby caused regressions for some webcams. Fix this by moving the calls back to pcm.c for now to make it work again and use snd_usb_endpoint_activate() to really tear down all remaining URBs in the flight, consequently fixing another regression caused by USB packets on the wire after altsetting 0 has been selected.

2012-07-12cpufreq / ACPI: Fix not loading acpi-cpufreq driver regressionThomas Renninger
Commit d640113fe80e45ebd4a5b420b introduced a regression on SMP systems where the processor core with ACPI id zero is disabled (typically should be the case because of hyperthreading). The regression got spread through stable kernels. On 3.0.X it got introduced via 3.0.18. Such platforms may be rare, but do exist. Look out for a disabled processor with acpi_id 0 in dmesg: ACPI: LAPIC (acpi_id[0x00] lapic_id[0x10] disabled) This problem has been observed on a: HP Proliant BL280c G6 blade This patch restricts the introduced workaround to platforms with nr_cpu_ids <= 1.

2012-07-12ARM: EXYNOS: register devices in 'need_restore' state for pm_domainsMarek Szyprowski
Commit ca1d72f033 ('PM / Domains: Make it possible to add devices to inactive domains') introduced possibility to add devices to inactive power domains and added pm_genpd_dev_need_restore() function which lets platform core to notify power domain core that the specified device must be restored (with its runtime_resume() callback) before first use. This patch adds the pm_genpd_dev_need_restore() call what brings back the suspend/resume behaviour for the client devices known from the previous power domain driver (removed by commit 91cfbd4ee0 - 'ARM: EXYNOS: Hook up power domains to generic power domain infrastructure'). Client device drivers relay on that suspend/resume behaviour, thus this patch fixes runtime pm operation for client devices.
