2013-12-18s390/3270: fix allocation of tty3270_screen structureMartin Schwidefsky
The tty3270_alloc_screen function is called from tty3270_install with swapped arguments, the number of columns instead of rows and vice versa. The number of rows is typically smaller than the number of columns which makes the screen array too big but the individual cell arrays for the lines too small. Creating lines longer than the number of rows will clobber the memory after the end of the cell array. The fix is simple, call tty3270_alloc_screen with the correct argument order.

2013-12-18s390/smp: improve setup of possible cpu maskHeiko Carstens
Since under z/VM we cannot have more than 64 cpus, make sure the cpu_possible_mask does not contain more bits. This avoids wasting memory for dynamic per-cpu allocations if CONFIG_NR_CPUS is larger than 64.

2013-12-18drm/i915: grab a pages pin count for preallocate stolenDaniel Vetter
But only when we indeed set up a gtt mapping. We need this since the vma also holds a pages_pin_count, on top of the unconditional pages_pin_count we grab for all stolen objects (to avoid swap-out). This should avoid a pages_pin_count underrun when cleaning up framebuffers objects taken over from the BIOS. Chris mentioned in his review that this bug even predates the vma conversion.

Commit caaa4c804fae ("KVM: PPC: Book3S HV: Fix physical address calculations") unfortunately resulted in some low-order address bits getting dropped in the case where the guest is creating a 4k HPTE and the host page size is 64k. By getting the low-order bits from hva rather than gpa we miss out on bits 12 - 15 in this case, since hva is at page granularity. This puts the missing bits back in.

2013-12-17e1000e: fix compiler warning (maybe-unitialized variable)David Ertman
This patch is to fix a compiler warning of maybe-uininitialized-variable that is generated from gcc when the -O3 flag is used. In the function e1000_reset_hw_80003es2lan(), the variable krmn_reg_data is first given a value by being passed to a register read function as a pass-by-reference parameter. But, the return value of that read function was never checked to see if the read failed and the variable not given an initial value. The compiler was smart enough to spot this. This patch is to check the return value for that read function and return it, if an error occurs, without trying to utilize the value in kmrn_reg_data.

2013-12-18ext4: fix deadlock when writing in ENOSPC conditionsJan Kara
Akira-san has been reporting rare deadlocks of his machine when running xfstests test 269 on ext4 filesystem. The problem turned out to be in ext4_da_reserve_metadata() and ext4_da_reserve_space() which called ext4_should_retry_alloc() while holding i_data_sem. Since ext4_should_retry_alloc() can force a transaction commit, this is a lock ordering violation and leads to deadlocks. Fix the problem by just removing the retry loops. These functions should just report ENOSPC to the caller (e.g. ext4_da_write_begin()) and that function must take care of retrying after dropping all necessary locks.

2013-12-17net: allow netdev_all_upper_get_next_dev_rcu with rtnl lock heldJohn Fastabend
It is useful to be able to walk all upper devices when bringing a device online where the RTNL lock is held. In this case it is safe to walk the all_adj_list because the RTNL lock is used to protect the write side as well. This patch adds a check to see if the rtnl lock is held before throwing a warning in netdev_all_upper_get_next_dev_rcu(). Also because we now have a call site for lockdep_rtnl_is_held() outside COFIG_LOCK_PROVING an inline definition returning 1 is needed. Similar to the rcu_read_lock_is_held().

David Herrmann dutifully moved this locking along when moving the agp_init call out of the generic drm_dev_register into the pci specific load helpers. But afaict there's no need and the reason for that locking has been purely a historical accident - we need the lock around the driver dev node registration to paper over the midlayer init races, and the agp init simply ended up in there. The real fix for all this is of course to delay the dev (and sysfs/debugfs) interface registration until everything is fully set up. Until then stop the cargo-cult locking from spreading and remove the locking.
