2013-12-28ARM: pxa: fix USB gadget driver compilation regressionLinus Walleij1-0/+2
After commit 88f718e3fa4d67f3a8dbe79a2f97d722323e4051 "ARM: pxa: delete the custom GPIO header" a compilation error was introduced in the PXA25x gadget driver. An attempt to fix the problem was made in commit b144e4ab1ef130e8bf30bcd3e529b7f35112c503 "usb: gadget: fix pxa25x compilation problems" by explictly stating the driver needs the <mach/hardware.h> header, which solved the compilation for a few boards, such as the pxa255-idp and its defconfig. However the Lubbock board has this special clause in drivers/usb/gadget/pxa25x_udc.c: This include file has an implicit dependency on <mach/irqs.h> having been included before <mach/lubbock.h> was included. Before commit 88f718e3fa4d67f3a8dbe79a2f97d722323e4051 "ARM: pxa: delete the custom GPIO header" this implicit dependency for the pxa25x_udc compile on the Lubbock was satisfied by <linux/gpio.h> implicitly including <mach/gpio.h> which was in turn including <mach/irqs.h>, apart from the earlier added <mach/hardware.h>. Fix this by having the PXA25x <mach/lubbock.h> explicitly include <mach/irqs.h>.

2013-12-27ARM: OMAP2+: Fix LCD panel backlight regression for LDP legacy bootingTony Lindgren1-1/+6
Looks like the LCD panel on LDP has been broken quite a while, and recently got fixed by commit 0b2aa8bed3e1 (gpio: twl4030: Fix regression for twl gpio output). However, there's still an issue left where the panel backlight does not come on if the LCD drivers are built into the kernel. Fix the issue by registering the DPI LCD panel only after the twl4030 GPIO has probed.

2013-12-25ARM: OMAP2+: hwmod_data: fix missing OMAP_INTC_START in irq dataSuman Anna2-5/+5
Commit 7d7e1eb (ARM: OMAP2+: Prepare for irqs.h removal) and commit ec2c082 (ARM: OMAP2+: Remove hardcoded IRQs and enable SPARSE_IRQ) updated the way interrupts for OMAP2/3 devices are defined in the HWMOD data structures to being an index plus a fixed offset (defined by OMAP_INTC_START). Couple of irqs in the OMAP2/3 hwmod data were misconfigured completely as they were missing this OMAP_INTC_START relative offset. Add this offset back to fix the incorrect irq data for the following modules: OMAP2 - GPMC, RNG OMAP3 - GPMC, ISP MMU & IVA MMU Signed-off-by: Suman Anna <s-anna@ti.com> Fixes: 7d7e1eba7e92 ("ARM: OMAP2+: Prepare for irqs.h removal") Fixes: ec2c0825ca31 ("ARM: OMAP2+: Remove hardcoded IRQs and enable SPARSE_IRQ") Cc: Tony Lindgren <tony@atomide.com> Signed-off-by: Paul Walmsley <paul@pwsan.com>

It's an ugly hack working around a deadlock condition between driver core resume and block layer device removal paths through freezer which was made more reproducible by writeback being converted to workqueue some releases ago. The bug has nothing to do with libata but it's just an workaround which is easy to backport. After discussion, Rafael and I seem to agree that we don't really need kernel freezables - both kthread and workqueue. There are few specific workqueues which constitute PM operations and require freezing, which will be converted to use workqueue_set_max_active() instead. All other kernel freezer uses are planned to be removed, followed by the removal of kthread and workqueue freezer support, hopefully. Others are device-specific fixes.

selinux_setprocattr() does ptrace_parent(p) under task_lock(p), but task_struct->alloc_lock doesn't pin ->parent or ->ptrace, this looks confusing and triggers the "suspicious RCU usage" warning because ptrace_parent() does rcu_dereference_check().

2013-12-22aio: clean up and fix aio_setup_ring page mappingLinus Torvalds1-35/+23
Since commit 36bc08cc01709 ("fs/aio: Add support to aio ring pages migration") the aio ring setup code has used a special per-ring backing inode for the page allocations, rather than just using random anonymous pages. However, rather than remembering the pages as it allocated them, it would allocate the pages, insert them into the file mapping (dirty, so that they couldn't be free'd), and then forget about them. And then to look them up again, it would mmap the mapping, and then use "get_user_pages()" to get back an array of the pages we just created. Now, not only is that incredibly inefficient, it also leaked all the pages if the mmap failed (which could happen due to excessive number of mappings, for example). So clean it all up, making it much more straightforward. Also remove some left-overs of the previous (broken) mm_populate() usage that was removed in commit d6c355c7dabc ("aio: fix race in ring buffer page lookup introduced by page migration support") but left the pointless and now misleading MAP_POPULATE flag around.

2013-12-22cpufreq: Use CONFIG_CPU_FREQ_DEFAULT_* to set initial policy for setpolicy ↵Jason Baron1-0/+6
drivers When configuring a default governor (via CONFIG_CPU_FREQ_DEFAULT_*) with the intel_pstate driver, the desired default policy is not properly set. For example, setting 'CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE' ends up with the 'powersave' policy being set. Fix by configuring the correct default policy, if either 'powersave' or 'performance' are requested. Otherwise, fallback to what the driver originally set via its 'init' routine.

2013-12-22cpufreq: remove sysfs files for CPUs which failed to come back after resumeViresh Kumar1-32/+31
There are cases where cpufreq_add_dev() may fail for some CPUs during system resume. With the current code we will still have sysfs cpufreq files for those CPUs and struct cpufreq_policy would be already freed for them. Hence any operation on those sysfs files would result in kernel warnings. Example of problems resulting from resume errors (from Bjørn Mork): WARNING: CPU: 0 PID: 6055 at fs/sysfs/file.c:343 sysfs_open_file+0x77/0x212() missing sysfs attribute operations for kobject: (null) Modules linked in: [stripped as irrelevant] CPU: 0 PID: 6055 Comm: grep Tainted: G D 3.13.0-rc2 #153 Hardware name: LENOVO 2776LEG/2776LEG, BIOS 6EET55WW (3.15 ) 12/19/2011 0000000000000009 ffff8802327ebb78 ffffffff81380b0e 0000000000000006 ffff8802327ebbc8 ffff8802327ebbb8 ffffffff81038635 0000000000000000 ffffffff811823c7 ffff88021a19e688 ffff88021a19e688 ffff8802302f9310 Call Trace: [<ffffffff81380b0e>] dump_stack+0x55/0x76 [<ffffffff81038635>] warn_slowpath_common+0x7c/0x96 [<ffffffff811823c7>] ? sysfs_open_file+0x77/0x212 [<ffffffff810386e3>] warn_slowpath_fmt+0x41/0x43 [<ffffffff81182dec>] ? sysfs_get_active+0x6b/0x82 [<ffffffff81182382>] ? sysfs_open_file+0x32/0x212 [<ffffffff811823c7>] sysfs_open_file+0x77/0x212 [<ffffffff81182350>] ? sysfs_schedule_callback+0x1ac/0x1ac [<ffffffff81122562>] do_dentry_open+0x17c/0x257 [<ffffffff8112267e>] finish_open+0x41/0x4f [<ffffffff81130225>] do_last+0x80c/0x9ba [<ffffffff8112dbbd>] ? inode_permission+0x40/0x42 [<ffffffff81130606>] path_openat+0x233/0x4a1 [<ffffffff81130b7e>] do_filp_open+0x35/0x85 [<ffffffff8113b787>] ? __alloc_fd+0x172/0x184 [<ffffffff811232ea>] do_sys_open+0x6b/0xfa [<ffffffff811233a7>] SyS_openat+0xf/0x11 [<ffffffff8138c812>] system_call_fastpath+0x16/0x1b To fix this, remove those sysfs files or put the associated kobject in case of such errors. Also, to make it simple, remove the cpufreq sysfs links from all the CPUs (except for the policy->cpu) during suspend, as that operation won't result in a loss of sysfs file permissions and we can create those links during resume just fine.

2013-12-21aio/migratepages: make aio migrate pages saneBenjamin LaHaise3-15/+53
The arbitrary restriction on page counts offered by the core migrate_page_move_mapping() code results in rather suspicious looking fiddling with page reference counts in the aio_migratepage() operation. To fix this, make migrate_page_move_mapping() take an extra_count parameter that allows aio to tell the code about its own reference count on the page being migrated. While cleaning up aio_migratepage(), make it validate that the old page being passed in is actually what aio_migratepage() expects to prevent misbehaviour in the case of races.

In the case of both the submit_queues param and use_per_node_hctx param are used. We limit the number af submit_queues to the number of online nodes. If the submit_queues is a multiple of nr_online_nodes, its trivial. Simply map them to the nodes. For example: 8 submit queues are mapped as node0[0,1], node1[2,3], ... If uneven, we are left with an uneven number of submit_queues that must be mapped. These are mapped toward the first node and onward. E.g. 5 submit queues mapped onto 4 nodes are mapped as node0[0,1], node1[2], ... Signed-off-by: Matias Bjorling <m@bjorling.me> Signed-off-by: Jens Axboe <axboe@kernel.dk>

2013-12-20Don't set the INITRD_COMPRESS environment variable automaticallyLinus Torvalds1-1/+3
Commit 1bf49dd4be0b ("./Makefile: export initial ramdisk compression config option") started setting the INITRD_COMPRESS environment variable depending on which decompression models the kernel had available. That is completely broken. For example, we by default have CONFIG_RD_LZ4 enabled, and are able to decompress such an initrd, but the user tools to *create* such an initrd may not be availble. So trying to tell dracut to generate an lz4-compressed image just because we can decode such an image is completely inappropriate.
