Staging tree patches for 3.3-rc3 Big things here is the deletion of the Android pmem driver, as it's obsolete and no one uses it, the gma500 driver as it's already in the drm portion of the kernel tree, and the pohmelfs filesystem as it's obsolete and a rewritten version is being proposed for the fs/ section of the kernel. Other than that, a smattering of different bugfixes and regressions, and some omap drm api merge fixups that were needed due to api changes in the main portion of the drm tree, allowing this code to build properly again.

The receive FIFO wakeup latency estimate in the omap-serial driver is three orders of magnitude too small. This effectively prevents the MPU from going to a low-power state when CONFIG_CPU_IDLE=y. This is a major power management regression and masks some other FIFO-related bugs in the driver. Fix by correcting the most egregious problem in the RX wakeup latency estimate. There are several other flaws in the estimator; these will be fixed by a separate patch series intended for 3.4. The difference in low-power states with this patch can be observed via debugfs in pm_debug/count. This estimate does not have any effect when CONFIG_CPU_IDLE=n. Signed-off-by:

Prevent OMAP UARTs from going idle while they are still transferring data in PIO mode. This works around an oversight in the OMAP UART hardware present in OMAP34xx and earlier: an idle UART won't send a wakeup when the TX FIFO threshold is reached. This causes long delays during data transmission when the MPU powerdomain enters a low-power mode. The MPU interrupt controller is not able to respond to interrupts when it's in a low-power state, so the TX buffer is not refilled until another wakeup event occurs. This fix changes the erratum i291 DMA idle workaround. Rather than toggling between force-idle and no-idle, it will toggle between smart-idle and no-idle. The important part of the workaround is the no-idle part, so this shouldn't result in any change in behavior. This fix should work on all OMAP UARTs. Future patches intended for the 3.4 merge window will make this workaround conditional on a "feature" flag, and will use the OMAP36xx+ TX event wakeup support. Thanks to Kevin Hilman <khilman@ti.com> for mentioning the erratum i291 workaround, which led to the development of this approach. Signed-off-by:

In the (default) PIO mode, use a one-byte RX FIFO threshold. The OMAP UART IP blocks do not appear to be capable of waking the system under an RX timeout condition. Since the previous RX FIFO threshold was 16 bytes, this meant that omap-serial.c did not become aware of any received data until all those bytes arrived or until another UART interrupt occurred. This made the serial console and presumably other serial applications (GPS, serial Bluetooth) unusable or extremely slow. A 1-byte RX FIFO threshold also allows the MPU to enter a low-power consumption state while waiting for the FIFO to fill. This can be verified using the serial console by comparing the behavior when "0123456789abcde" is pasted in from another window, with the behavior when "0123456789abcdef" is pasted in. Since the former string is less than sixteen bytes long, the string is not echoed for some time, while the latter string is echoed immediately. DMA operation is unaffected by this patch. Thanks to Russell King - ARM Linux <linux@arm.linux.org.uk> for some additional information on the standard behavior of the RX timeout event, which was used to improve this commit description.

_parse_integer() does one or two division instructions (which are slow) per digit parsed to perform the overflow check. Furthermore, these are particularly expensive examples of division instruction as the number of clock cycles required to complete them may go up with the position of the most significant set bit in the dividend: if (*res > div_u64(ULLONG_MAX - val, base)) which is as maximal as possible. Worse, on 32-bit arches, more than one of these division instructions may be required per digit. So, assuming we don't support a base of more than 16, skip the check if the top nibble of the result is not set at this point. Signed-off-by:
David Howells <dhowells@redhat.com> [ Changed it to not dereference the pointer all the time - even if the compiler can and does optimize it away, the code just looks cleaner.

This fixes a memory-corrupting bug: not only does it cause the warning, but as a result of dropping the refcount to zero, it causes the pcmcia_socket0 device structure to be freed while it still has references, causing slab caches corruption. A fatal oops quickly follows this warning - often even just a 'dmesg' following the warning causes the kernel to oops. While testing suspend/resume on an ARM device with PCMCIA support, and a CF card inserted, I found that after five suspend and resumes, the kernel would complain, and shortly die after with slab corruption. WARNING: at include/linux/kref.h:41 kobject_get+0x28/0x50() As the message doesn't give a clue about which kobject, and the built-in debugging in drivers/base/power/main.c happens too late, this was added right before each get_device(): printk("%s: %p [%s] %u\n", __func__, dev, kobject_name(&dev->kobj), atomic_read(&dev->kobj.kref.refcount)); and on the 3rd s2ram cycle, the following behaviour observed: On the 3rd suspend/resume cycle: dpm_prepare: c1a0d998 [pcmcia_socket0] 3 dpm_suspend: c1a0d998 [pcmcia_socket0] 3 dpm_suspend_noirq: c1a0d998 [pcmcia_socket0] 3 dpm_resume_noirq: c1a0d998 [pcmcia_socket0] 3 dpm_resume: c1a0d998 [pcmcia_socket0] 3 dpm_complete: c1a0d998 [pcmcia_socket0] 2 4th: dpm_prepare: c1a0d998 [pcmcia_socket0] 2 dpm_suspend: c1a0d998 [pcmcia_socket0] 2 dpm_suspend_noirq: c1a0d998 [pcmcia_socket0] 2 dpm_resume_noirq: c1a0d998 [pcmcia_socket0] 2 dpm_resume: c1a0d998 [pcmcia_socket0] 2 dpm_complete: c1a0d998 [pcmcia_socket0] 1 5th: dpm_prepare: c1a0d998 [pcmcia_socket0] 1 dpm_suspend: c1a0d998 [pcmcia_socket0] 1 dpm_suspend_noirq: c1a0d998 [pcmcia_socket0] 1 dpm_resume_noirq: c1a0d998 [pcmcia_socket0] 1 dpm_resume: c1a0d998 [pcmcia_socket0] 1 dpm_complete: c1a0d998 [pcmcia_socket0] 0 ------------[ cut here ]------------ WARNING: at include/linux/kref.h:41 kobject_get+0x28/0x50() Modules linked in: ucb1x00_core Backtrace: [<c0212090>] (dump_backtrace+0x0/0x110) from [<c04799dc>] (dump_stack+0x18/0x1c) [<c04799c4>] (dump_stack+0x0/0x1c) from [<c021cba0>] (warn_slowpath_common+0x50/0x68) [<c021cb50>] (warn_slowpath_common+0x0/0x68) from [<c021cbdc>] (warn_slowpath_null+0x24/0x28) [<c021cbb8>] (warn_slowpath_null+0x0/0x28) from [<c0335374>] (kobject_get+0x28/0x50) [<c033534c>] (kobject_get+0x0/0x50) from [<c03804f4>] (get_device+0x1c/0x24) [<c0388c90>] (dpm_complete+0x0/0x1a0) from [<c0389cc0>] (dpm_resume_end+0x1c/0x20) ...

This creates an imbalance in the refcounting. Testing with pcmcia_put_socket() put removed shows that the bug is gone: dpm_suspend: c1a10998 [pcmcia_socket0] 5 dpm_suspend_noirq: c1a10998 [pcmcia_socket0] 5 dpm_resume_noirq: c1a10998 [pcmcia_socket0] 5 dpm_resume: c1a10998 [pcmcia_socket0] 5 dpm_complete: c1a10998 [pcmcia_socket0] 5 Tested-by:Russell King <rmk+kernel@arm.linux.org.uk> Signed-off-by:

In current code, pltfm->als_vmin is set to LM3530_ALS_WINDOW_mV and pltfm->als_vmax is 0. This does not make sense. I think what we want here is setting pltfm->als_vmax to LM3530_ALS_WINDOW_mV.

When isolating pages for migration, migration starts at the start of a zone while the free scanner starts at the end of the zone. Migration avoids entering a new zone by never going beyond the free scanned. Unfortunately, in very rare cases nodes can overlap. When this happens, migration isolates pages without the LRU lock held, corrupting lists which will trigger errors in reclaim or during page free such as in the following oops BUG: unable to handle kernel NULL pointer dereference at 0000000000000008 IP: [<ffffffff810f795c>] free_pcppages_bulk+0xcc/0x450 PGD 1dda554067 PUD 1e1cb58067 PMD 0 Oops: 0000 [#1] SMP CPU 37 Pid: 17088, comm: memcg_process_s Tainted: G X RIP: free_pcppages_bulk+0xcc/0x450 Process memcg_process_s (pid: 17088, threadinfo ffff881c2926e000, task ffff881c2926c0c0) Call Trace: free_hot_cold_page+0x17e/0x1f0 __pagevec_free+0x90/0xb0 release_pages+0x22a/0x260 pagevec_lru_move_fn+0xf3/0x110 putback_lru_page+0x66/0xe0 unmap_and_move+0x156/0x180 migrate_pages+0x9e/0x1b0 compact_zone+0x1f3/0x2f0 compact_zone_order+0xa2/0xe0 try_to_compact_pages+0xdf/0x110 __alloc_pages_direct_compact+0xee/0x1c0 __alloc_pages_slowpath+0x370/0x830 __alloc_pages_nodemask+0x1b1/0x1c0 alloc_pages_vma+0x9b/0x160 do_huge_pmd_anonymous_page+0x160/0x270 do_page_fault+0x207/0x4c0 page_fault+0x25/0x30 The "X" in the taint flag means that external modules were loaded but but is unrelated to the bug triggering.

The stub_probe function can be called as soon as the stub_driver is registered. This can lead to the busid_table_lock being used before it is initialized. Moved calling the init_busid_table function (which initalizes this spinlock) to be called earlier in the init function to prevent this from happening. Signed-off-by:

When this driver was upgraded to the vendor 20100831 version in commit 93c55dda et al,, one listhead initialization was missed. This broke complete operation of the driver whenever AP mode was enabled. This patch fixes https://bugs.archlinux.org/task/27996. Signed-off-by:

This structure is still used after it has been freed, since it is being allocated in probe, calls to free it have been moved to module's remove routine. This should fix the follwoing messages when attempting to remove the module: drv_get_first_dev_extension: Failed to retrieve the object handle drv_get_first_dev_extension: Failed to retrieve the object handle drv_destroy: Failed to store DRV object mgr_destroy: Failed to store MGR object Signed-off-by:

There are two members of pr_ctxt allocated during bridge_open that are never freed resulting in memory leaks, these are stream_id and node_id, they are now freed on release of the handle (bridge_release) right before freeing pr_ctxt. Error path for bridge_open was also fixed since the same variables could result in memory leaking due to missing handling of failure scenarios. While at it, the indentation changes were introduced to avoid interleaved goto statements inside big if blocks. Signed-off-by:

If a process forked and the child process was killed by the lowmemorykiller, the lowmemory killer would be disabled until the parent process reaped the child or it died itself. Signed-off-by:

In a multithreaded workload, the zv_curr_dist_counts and zv_cumul_dist_counts statistics are being corrupted because the increments and decrements in zv_create and zv_free are not atomic. This patch converts these statistics and their corresponding increments/decrements/reads to atomic operations. Signed-off-by:
