* bcma: add PCIe host controllerHauke Mehrtens2012-02-061-5/+44
| | | | | | | | | | Some SoCs have a PCIe host controller to make it possible to attach some other devices to it, like an other Wifi card. This code was tested with an Netgear WNDR3400 (bcm4716 based), but should work with all bcma based SoCs. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by: John W.

Then they merge the patch and the selftest code dies. Sometimes we paste it into the changelog. Sometimes the code gets thrown into Documentation/(!). This saddens me. So this patch creates a bare-bones framework which will henceforth allow me to ask people to include their test apps in the kernel tree so we can keep them alive. Then when people enhance or fix the feature, I can ask them to update the test app too. The infrastruture is terribly trivial at present - let's see how it evolves. - checkpoint/restart feature work. A note on this: this is a project by various mad Russians to perform c/r mainly from userspace, with various oddball helper code added into the kernel where the need is demonstrated. So rather than some large central lump of code, what we have is little bits and pieces popping up in various places which either expose something new or which permit something which is normally kernel-private to be modified. The overall project is an ongoing thing. I've judged that the size and scope of the thing means that we're more likely to be successful with it if we integrate the support into mainline piecemeal rather than allowing it all to develop out-of-tree. However I'm less confident than the developers that it will all eventually work! So what I'm asking them to do is to wrap each piece of new code inside CONFIG_CHECKPOINT_RESTORE. So if it all eventually comes to tears and the project as a whole fails, it should be a simple matter to go through and delete all trace of it. This lot pretty much wraps up the -rc1 merge for me. * akpm: (96 commits) unlzo: fix input buffer free ramoops: update parameters only after successful init ramoops: fix use of rounddown_pow_of_two() c/r: prctl: add PR_SET_MM codes to set up mm_struct entries c/r: procfs: add start_data, end_data, start_brk members to /proc/$pid/stat v4 c/r: introduce CHECKPOINT_RESTORE symbol selftests: new x86 breakpoints selftest selftests: new very basic kernel selftests directory radix_tree: take radix_tree_path off stack radix_tree: remove radix_tree_indirect_to_ptr() dio: optimize cache misses in the submission path vfs: cache request_queue in struct block_device fs/direct-io.c: calculate fs_count correctly in get_more_blocks() drivers/parport/parport_pc.c: fix warnings panic: don't print redundant backtraces on oops sysctl: add the kernel.ns_last_pid control kdump: add udev events for memory online/offline include/linux/crash_dump.h needs elf.h kdump: fix crash_kexec()/smp_send_stop() race in panic() kdump: crashk_res init check for /sys/kernel/kexec_crash_size ...

| * mm,slub,x86: decouple size of struct page from CONFIG_CMPXCHG_LOCALHeiko Carstens2012-01-122-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While implementing cmpxchg_double() on s390 I realized that we don't set CONFIG_CMPXCHG_LOCAL despite the fact that we have support for it. However setting that option will increase the size of struct page by eight bytes on 64 bit, which we certainly do not want. Also, it doesn't make sense that a present cpu feature should increase the size of struct page. Besides that it looks like the dependency to CMPXCHG_LOCAL is wrong and that it should depend on CMPXCHG_DOUBLE instead. This patch: If an architecture supports CMPXCHG_LOCAL this shouldn't result automatically in larger struct pages if the SLUB allocator is used. Instead introduce a new config option "HAVE_ALIGNED_STRUCT_PAGE" which can be selected if a double word aligned struct page is required. Also update x86 Kconfig so that it should work as before.

The code worked this way until commit 7cfe561 "ASoC: wm8903: Expose GPIOs through gpiolib", where the behaviour was changed due to my lack of awareness of the above rationale. This patch reverts to the intended behaviour, and updates all in-tree users to use the correct scheme. This also makes WM8903 consistent with other devices that use a similar scheme. WM8903_GPIO_NO_CONFIG is also renamed to WM8903_GPIO_CONFIG_ZERO so that its name accurately reflects its purpose.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch contains r8a7779 SMP support V3 - now including CPU hotplug offine and online support. The r8a7779 power domain code is tied together with SMP glue code which allows us to control the power domains via CPU hotplug. At this point the kernel boots with the 4 Cortex-A9 cores in SMP mode and all CPU cores except CPU0 can be hotplugged. The code in platsmp.c is quite far from pretty, but it is kept like that intentionally to avoid creating layers of code that will go away in the near future anyway. The code needs to be updated when some per-SoC handling code will be added to the ARM architecture, see the following patch for more information: "[RFC PATCH 0/3] Per SoC descriptor" Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

This adds support for 4 power domains for I/O Devices together with code that can be used for CPU cores as well. The only out of the ordinary experience is the need for ioremap() of SYSC registers. Because of that we need to execute some init function before setting up the domains. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
