git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging 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.

2012-02-08pcmcia: fix socket refcount decrementing on each resumeRussell King
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.

2012-02-08drivers/leds/leds-lm3530.c: fix setting pltfm->als_vmaxAxel Lin
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. Both als_vmin and als_vmax local variables will be set to pltfm->als_vmin and pltfm->als_vmax by a few lines latter. Thus also remove a redundant assignment for als_vmin and als_vmax in this patch.

Error path for bridge_open was also fixed since the same variables could result in memory leaking due to missing handling of failure scenarios.

2012-02-08zcache: Set SWIZ_BITS to 8 to reduce tmem bucket lock contention.Dan Magenheimer
SWIZ_BITS > 8 results in a much larger number of "tmem_obj" allocations, likely one per page-placed-in-frontswap. The tmem_obj is not huge (roughly 100 bytes), but it is large enough to add a not-insignificant memory overhead to zcache. The SWIZ_BITS=8 will get roughly the same lock contention without the space wastage. The effect of SWIZ_BITS can be thought of as "2^SWIZ_BITS is the number of unique oids that be generated" (This concept is limited to frontswap's use of tmem).

2012-02-08zcache: fix deadlock conditionDan Magenheimer
I discovered this deadlock condition awhile ago working on RAMster but it affects zcache as well. The list spinlock must be locked prior to the page spinlock and released after. As a result, the page copy must also be done while the locks are held. Applies to 3.2. Konrad, please push (via GregKH?)... this is definitely a bug fix so need not be pushed during a -rc0 window.

2012-02-08staging: drm/omap: fix locking issueRob Clark
The create/free mmap offset code must be synchronized. Yet only some callers of omap_gem_mmap_offset() held struct_mutex. Leading to various crashes around drm_mm_insert_helper_range(). (In the free-object path, which is currently the only place we drm_gem_free_mmap_offset(), struct_mutex is already held.)

2012-02-08staging: drm/omap: multiplanar and YUV supportRob Clark
Add support in framebuffer objects for other color formats and multi- planar YUV (NV12). Since this requires changing the API between the plane and fb for getting scanout information (paddr, etc), take advantage of the opportunity and put in place a way to allow fb's to be unpinned when they are not being scanned out. Now, before start of scanout the plane calls omap_framebuffer_pin() which takes care to pin all the backing bo's, then omap_framebuffer_update_scanout() however many times to update the scanout address(es), etc, and then when finished omap_framebuffer_unpin().

2012-02-08staging: drm/omap: add drm_plane supportRob Clark
Because framebuffer layer and overlay scanout video pipes are basically thing in OMAP display subsystem (the only difference being that the first video pipe does not support scaling or YUV formats), much of the CRTC code is pulled into the plane implementation, and a private plane object is used by the CRTC object. This avoids code duplication between the plane and CRTC. Signed-off-by: Rob Clark <rob@ti.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

Use IP_FREEBIND socket option so that iscsi portal configuration with explicit IP addresses can happen during boot, before network interfaces have been assigned IPs. This is especially important on systemd based Linux boxes where system boot happens asynchronously and non-trivial configuration must be done to get targetcli.service to start synchronously after the network is configured.
