* mm: bring back /sys/kernel/mmHugh Dickins2014-01-271-1/+1
| | | | | | | | | | | | | | | | | | Commit da29bd36224b ("mm/mm_init.c: make creation of the mm_kobj happen earlier than device_initcall") changed to pure_initcall(mm_sysfs_init). That's too early: mm_sysfs_init() depends on core_initcall(ksysfs_init) to have made the kernel_kobj directory "kernel" in which to create "mm". Make it postcore_initcall(mm_sysfs_init). We could use core_initcall(), and depend upon Makefile link order kernel/ mm/ fs/ ipc/ security/ ... as core_initcall(debugfs_init) and core_initcall(securityfs_init) do; but better not.

* Revert "mm/vmalloc: interchage the implementation of vmalloc_to_{pfn,page}"malc2014-01-271-10/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Revert commit ece86e222db4, which was intended as a small performance improvement. Despite the claim that the patch doesn't introduce any functional changes in fact it does. The "no page" path behaves different now. Originally, vmalloc_to_page might return NULL under some conditions, with new implementation it returns pfn_to_page(0) which is not the same as NULL. Simple test shows the difference. test.c #include <linux/kernel.h> #include <linux/module.h> #include <linux/vmalloc.h> #include <linux/mm.h> int __init myi(void) { struct page *p; void *v; v = vmalloc(PAGE_SIZE); /* trigger the "no page" path in vmalloc_to_page*/ vfree(v); p = vmalloc_to_page(v); pr_err("expected val = NULL, returned val = %p", p); return -EBUSY; } void __exit mye(void) { } module_init(myi) module_exit(mye) Before interchange: expected val = NULL, returned val = (null) After interchange: expected val = NULL, returned val = c7ebe000 Signed-off-by: Vladimir Murzin <murzin.v@gmail.com> Cc: Jianyu Zhan <nasa4836@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* memblock: don't silently align size in memblock_virt_alloc()Yinghai Lu2014-01-271-6/+0
| | | | | | | | | | | | | | | | | | | | | | | In original __alloc_memory_core_early() for bootmem wrapper, we do not align size silently. We should not do that, as later free with old size will leave some range not freed. It's obvious that code is copied from memblock_base_nid(), and that code is wrong for the same reason. Also remove that in memblock_alloc_base.

* x86: revert wrong memblock current limit settingYinghai Lu2014-01-272-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | Dave reported big numa system booting is broken. It turns out that commit 5b6e529521d3 ("x86: memblock: set current limit to max low memory address") sets the limit to low wrongly. max_low_pfn_mapped is different from max_pfn_mapped. max_low_pfn_mapped is always under 4G. That will memblock_alloc_nid all go under 4G. Revert 5b6e529521d3 to fix a no-boot regression which was triggered by 457ff1de2d24 ("lib/swiotlb.c: use memblock apis for early memory allocations").

Nothing needs to be extracted from the device tree node by the PWM device. Client devices need only specify the period; the per-chip index is implicitly zero because one device node must be present for each PWM output in use. This approach is more convenient due to the wide variability in the number of PWM channels present across the various PXA variants, and is made possible by the fact that the register sets for each PWM channel are segregated from each other. An of_xlate() method is added to parse this single-cell node. The existing ID table is reused for the match table data. Tested on a Palm Treo 680 (both platform data and DT cases).

This requires actual support by the controller. The only ones currently known to support it are Agere/LSI FW643. Most if not all other OHCI-1394 controllers do not implement the optional Physical Upper Bound register. With them, RDMA will continue to be limited to the lowermost 4 GB. firewire-ohci's startup message in the kernel log is augmented to tell whether the controller does expose more than 4 GB to RDMA. While OHCI-1394 allows for a maximum Physical Upper Bound of 0xffff'0000'0000 (near 256 TB), this implementation sets it to 0x8000'0000'0000 (128 TB) in order to avoid interference with applications that require interrupt-served asynchronous request reception at respectively low addresses. Note, this change does not switch remote DMA on. It only increases the range of remote access to all memory (instead of just 4 GB) whenever remote DMA was switched on by other means. The latter is achieved by setting firewire-ohci's remote_dma parameter, or if the physical DMA filter is opened through firewire-sbp2.

It's a NOOP since 2.6.35 and it will be removed one day. Comments mentioning IRQF_DISABLED are also updated, knowing that all interrupts are now "fast interrupts", their handlers running with interrupts disabled. Don't hesitate to let me know if you have other ways of rephrasing the comments!

If that GPIO is not configured, then the host controller will not wake up. Fix that for the affected devices by not enabling runtime PM unless the GPIO is successfully set up. This affects BYT sd card host controller which had runtime PM enabled from v3.11. For completeness, the MFD sd card host controller is flagged also. The original patch before rebasing (see link below) was tested on v3.11.10 and v3.12.4 although the patch applied with some offsets and fuzz.

However it is possible for commands to take even longer than that. Change the timer timeout to reflect the command timeout.

Add a quirk to handle this case. The fixup here is to issue a dummy CMD52 read to function 0 register 0xff, and this dummy read must be right after SDIO_CCCR_INTx is read. Patch has been verified on a dw_mmc controller (Samsung Chromebook) with MMC_CAP_SDIO_IRQ disabled.
