Cards typically have 5-7 scratch registers; one of these is reserved for rdev->rptr_save_reg. Unfortunately the reservation is done in function r100_cp_init, which is called by all drivers except r600 - and this function is also invoked on resume from suspend. After several resumes, no scratch registers are free and graphics acceleration is disabled. Dmesg then reports either: *ERROR* radeon: cp failed to get scratch reg (-22). *ERROR* radeon: cp isn't working(-22). radeon 0000:01:00.0: failed initializing CP (-22). or: *ERROR* radeon: failed to get scratch reg (-22). *ERROR* radeon: failed testing IB on GFX ring (-22). *ERROR* ib ring test failed (-22). The chain of calls on boot for all except r600 is: radeon_init -> ... -> (rXXX_init) -> rXXX_startup -> r100_cp_init The chain of calls on resume for all except r600 is: rXXX_resume -> rXXX_startup -> r100_cp_init. R600 correctly allocates rptr_save_reg in r600_init (ie once only, not in resume). However moving the code into the init functions for all drivers means touching 4 drivers. So instead, this patch just adds a test in r100_cp_init to avoid reallocating on resume. As the rdev structure is allocated via kzalloc in radeon_driver_load_kms, and zero is not a valid registerid, zero safely implies not-yet-allocated.

Only increase the higher 32bits if we really detect a wrap around. v2: instead of increasing the higher 32bits just use the higher 32bits from the last emitted fence. v3: also use last emitted fence value as upper limit. The intention of this patch is to make fences as robust as they where before introducing 64bit fences. This is necessary because on older systems it looks like the fence value gets corrupted on initialization.

Pull workqueue fixes from Tejun Heo: "It's later than I'd like but well the timing just didn't work out this time. There are three bug fixes. One from before 3.6-rc1 and two from the new CPU hotplug code. Kudos to Lai for discovering all of them and providing fixes. * Atomicity bug when clearing a flag and setting another. The two operation should have been atomic but wasn't. This bug has existed for a long time but is unlikely to have actually happened. Fix is safe. Marked for -stable. * If CPU hotplug cycles happen back-to-back before workers finish the previous cycle, the states could get out of sync and it could get stuck. Fixed by waiting for workers to complete before finishing hotplug cycle. * While CPU hotplug is in progress, idle workers could be depleted which can then lead to deadlock. I think both happening together is highly unlikely but still better to fix it and the fix isn't too scary. There's another workqueue related regression which reported a few days ago: https://bugzilla.kernel.org/show_bug.cgi?id=47301 It's a bit of head scratcher but there is a semi-reliable reproduce case, so I'm hoping to resolve it soonish." * 'for-3.6-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq: workqueue: fix possible idle worker depletion across CPU hotplug workqueue: restore POOL_MANAGING_WORKERS workqueue: fix possible deadlock in idle worker rebinding workqueue: move WORKER_REBIND clearing in rebind_workers() to the end of the function workqueue: UNBOUND -> REBIND morphing in rebind_workers() should be atomic

The authenc code doesn't deal with zero-length associated data correctly and ends up constructing a zero-length sg entry which causes a crash when it's fed into the crypto system. This patch fixes this by avoiding the code-path that triggers the SG construction if we have no associated data. This isn't the most optimal fix as it means that we'll end up using the fallback code-path even when we could still execute the digest function. However, this isn't a big deal as nobody but the test path would supply zero-length associated data.

Commit 1f2bfbd0 ("kbuild: link of vmlinux moved to a script") introduced in v3.5-rc1 broke kallsyms on architectures which have symbol prefixes. The --symbol-prefix argument used to be added to the KALLSYMS command line from the architecture Makefile, however this isn't picked up by the new scripts/link-vmlinux.sh. This resulted in symbols like kallsyms_addresses being added which weren't correctly overriding the weak symbols such as _kallsyms_addresses. These could then trigger BUG_ONs in kallsyms code. This is fixed by removing the KALLSYMS addition from the architecture Makefile, and using CONFIG_SYMBOL_PREFIX in the link-vmlinux.sh script to determine whether to add the --symbol-prefix argument.

To simplify both normal and CPU hotplug paths, worker management is prevented while CPU hoplug is in progress. This is achieved by CPU hotplug holding the same exclusion mechanism used by workers to ensure there's only one manager per pool. If someone else seems to be performing the manager role, workers proceed to execute work items. CPU hotplug using the same mechanism can lead to idle worker depletion because all workers could proceed to execute work items while CPU hotplug is in progress and CPU hotplug itself wouldn't actually perform the worker management duty - it doesn't guarantee that there's an idle worker left when it releases management. This idle worker depletion, under extreme circumstances, can break forward-progress guarantee and thus lead to deadlock. This patch fixes the bug by using separate mechanisms for manager exclusion among workers and hotplug exclusion. For manager exclusion, POOL_MANAGING_WORKERS which was restored by the previous patch is used. pool->manager_mutex is now only used for exclusion between the elected manager and CPU hotplug. The elected manager won't proceed without holding pool->manager_mutex. This ensures that the worker which won the manager position can't skip managing while CPU hotplug is in progress. It will block on manager_mutex and perform management after CPU hotplug is complete. Note that hotplug may happen while waiting for manager_mutex. A manager isn't either on idle or busy list and thus the hoplug code can't unbind/rebind it. Make the manager handle its own un/rebinding. tj: Updated comment and description.
