2011-01-20smp: Allow on_each_cpu() to be called while early_boot_irqs_disabled status ↵Tejun Heo1-4/+7
to init/main.c percpu may end up calling vfree() during early boot which in turn may call on_each_cpu() for TLB flushes. The function of on_each_cpu() can be done safely while IRQ is disabled during early boot but it assumed that the function is always called with local IRQ enabled which ended up enabling local IRQ prematurely during boot and triggering a couple of warnings. This patch updates on_each_cpu() and smp_call_function_many() such on_each_cpu() can be used safely while early_boot_irqs_disabled is set.

2011-01-20lockdep: Move early boot local IRQ enable/disable status to init/main.cTejun Heo6-36/+15
During early boot, local IRQ is disabled until IRQ subsystem is properly initialized. During this time, no one should enable local IRQ and some operations which usually are not allowed with IRQ disabled, e.g. operations which might sleep or require communications with other processors, are allowed. lockdep tracked this with early_boot_irqs_off/on() callbacks. As other subsystems need this information too, move it to init/main.c and make it generally available. While at it, toggle the boolean to early_boot_irqs_disabled instead of enabled so that it can be initialized with %false and %true indicates the exceptional condition.

We sometimes need to map between the virtio device and the given pci device. One such use is OS installer that gets the boot pci device from BIOS and needs to find the relevant block device. Since it can't, installation fails. Instead of creating a top-level devices/virtio-pci directory, create each device under the corresponding pci device node. Symlinks to all virtio-pci devices can be found under the pci driver link in bus/pci/drivers/virtio-pci/devices, and all virtio devices under drivers/bus/virtio/devices.

2011-01-20lguest: example launcher to use guard pages, drop PROT_EXEC, fix limit logicPhilip Sanderson1-8/+15
PROT_EXEC seems to be completely unnecessary (as the lguest binary never executes there), and will allow it to work with SELinux (and more importantly, PaX :-) as they can/do forbid writable and executable mappings. Also, map PROT_NONE guard pages at start and end of guest memory for extra paranoia. I changed the length check to addr + size > guest_limit because >= is wrong (addr of 0, size of getpagesize() with a guest_limit of getpagesize() would false positive).

When NOHZ=y and high res timers are disabled (via cmdline or Kconfig) tick_nohz_switch_to_nohz() will notify the user about switching into NOHZ mode. Nothing is printed for the case where HIGH_RES_TIMERS=y. Fix this for the HIGH_RES_TIMERS=y case by duplicating the printk from the low res NOHZ path in the high res NOHZ path. This confused me since I was thinking 'dmesg | grep -i NOHZ' would tell me if NOHZ was enabled, but if I have hrtimers there is nothing.

2011-01-19perf: Fix find_get_context() vs perf_event_exit_task() raceOleg Nesterov1-14/+20
find_get_context() must not install the new perf_event_context if the task has already passed perf_event_exit_task(). If nothing else, this means the memory leak. Initially ctx->refcount == 2, it is supposed that perf_event_exit_task_context() should participate and do the necessary put_ctx(). find_lively_task_by_vpid() checks PF_EXITING but this buys nothing, by the time we call find_get_context() this task can be already dead. To the point, cmpxchg() can succeed when the task has already done the last schedule(). Change find_get_context() to populate task->perf_event_ctxp[] under task->perf_event_mutex, this way we can trust PF_EXITING because perf_event_exit_task() takes the same mutex. Also, change perf_event_exit_task_context() to use rcu_dereference(). Probably this is not strictly needed, but with or without this change find_get_context() can race with setup_new_exec()->perf_event_exit_task(), rcu_dereference() looks better.

In later patches, we're going to need to have finer-grained control over the addition and removal of these structs from the pending_mid_q and we'll need to be able to call the destructor while holding the spinlock.

2011-01-19cifs: don't fail writepages on -EAGAIN errorsJeff Layton1-12/+37
If CIFSSMBWrite2 returns -EAGAIN, then the error should be considered temporary. CIFS should retry the write instead of setting an error on the mapping and returning. For WB_SYNC_ALL, just retry the write immediately. In the WB_SYNC_NONE case, call redirty_page_for_writeback on all of the pages that didn't get written out and then move on. Also, fix up the handling of a short write with a successful return code. MS-CIFS says that 0 bytes_written means ENOSPC or EFBIG. It doesn't mention what a short, but non-zero write means, so for now treat it as we would an -EAGAIN return.

2011-01-19[media] hdpvr: reduce latency of i2c read/write w/recycled bufferJarod Wilson2-17/+16
The current hdpvr code kmalloc's a new buffer for every i2c read and write. Rather than do that, lets allocate a buffer in the driver's device struct and just use that every time. The size I've chosen for the buffer is the maximum size I could ascertain might be used by either ir-kbd-i2c or lirc_zilog, plus a bit of padding (lirc_zilog may use up to 100 bytes on tx, rounded that up to 128). Note that this might also remedy user reports of very sluggish behavior of IR receive with hdpvr hardware. v2: make sure (len <= (dev->i2c_buf)) [Jean Delvare] Reported-by: Jean Delvare <[email protected]> Acked-by: Jean Delvare <[email protected]> Signed-off-by: Jarod Wilson <[email protected]> Signed-off-by: Mauro Carvalho Chehab <[email protected]>
2011-01-19[media] hdpvr: enable IR partJarod Wilson5-77/+65
A number of things going on here, but the end result is that the IR part on the hdpvr gets enabled, and can be used with ir-kbd-i2c and/or lirc_zilog. First up, there are some conditional build fixes that come into play whether i2c is built-in or modular. Second, we're swapping out i2c_new_probed_device() for i2c_new_device(), as in my testing, probing always fails, but we *know* that all hdpvr devices have a z8 chip at 0x70 and 0x71. Third, we're poking at an i2c address directly without a client, and writing some magic bits to actually turn on this IR part (this could use some improvement in the future). Fourth, some of the i2c_adapter storage has been reworked, as the existing implementation used to lead to an oops following i2c changes c. 2.6.31. Earlier editions of this patch have been floating around the 'net for a while, including being patched into Fedora kernels, and they *do* work. This specific version isn't yet tested, beyond loading ir-kbd-i2c and confirming that it does bind to the RX address of the hdpvr. [[email protected]: I2C_CLASS_TV_ANALOG is not defined.

Fixes an egregious bug in mceusb driver, where the receiver was being put into idle mode far sooner than it should have, thanks to storing a timeout value that in us where it should be ns. Basically, the receiver kept going into idle mode before a trailing space had been fully received, which was causing problems for some protocols, most notably manifesting as lirc userspace never receiving a trailing space for any rc5 signals.

2011-01-19[media] v4l2-device: fix 'use-after-freed' oopsHans Verkuil1-0/+2
Fix a bug in v4l2_device_unregister where the sd pointer can be dereferenced after it was freed. Normally the i2c adapter is removed before this function is called. Removing the adapter will also unregister all subdevs on that adapter, so generally v4l2_device_unregister has nothing to do. However, in the case of a platform i2c bus that bus is generally not freed. In that case, after freeing the i2c subdevice the code will fall into the second block when it tests if the subdev is a SPI device. But by that time the subdev is already freed and the kernel oopses. The fix is trivial: continue with the loop after freeing the i2c or spi subdevice.
