The irqdomain semantics were supposed to be such that a linear domain would be used if the passed first_irq was zero or negative, but I got it wrong so only passing zero as first_irq will work properly.

2012-10-23pinctrl/nomadik: use irq_create_mapping()Linus Walleij
Since in the DT case, the linear domain path will not allocate descriptors for the IRQs, we need to use irq_create_mapping() for mapping hwirqs to Linux IRQs, so these descriptors get created on-the-fly in this case. ChangeLog v1->v2: - Just use irq_create_mapping() in the .to_irq function since this is called before unmasking or enabling any interrupt lines, so irq_find_mapping() should be sufficient for the IRQ handler function.

2012-10-23drm/ttm: Fix a theoretical race in ttm_bo_cleanup_refs()Thomas Hellstrom
In theory, that function could release the lru lock between checking for bo on ddestroy list and a successful reserve if the bo was already reserved, and the function was called with waiting reserves allowed. However, all current reservers of a bo on the ddestroy list would atomically take the bo off the list after a successful reserve so this race should not have been hit, so no need to backport for stable. This patch also fixes a case found by Maarten Lankhorst where ttm_mem_evict_first called with no_wait_gpu would incorrectly spin waiting for bo idle if trying to evict a busy buffer that also sits on the ddestroy list.

2012-10-22ARM: 7559/1: smp: switch away from the idmap before updating init_mm.mm_countWill Deacon
When booting a secondary CPU, the primary CPU hands two sets of page tables via the secondary_data struct: (1) swapper_pg_dir: a normal, cacheable, shared (if SMP) mapping of the kernel image (i.e. the tables used by init_mm). (2) idmap_pgd: an uncached mapping of the .idmap.text ELF section. The idmap is generally used when enabling and disabling the MMU, which includes early CPU boot. In this case, the secondary CPU switches to swapper as soon as it enters C code: struct mm_struct *mm = &init_mm; unsigned int cpu = smp_processor_id(); /* * All kernel threads share the same mm context; grab a * reference and switch to it. */ atomic_inc(&mm->mm_count); current->active_mm = mm; cpumask_set_cpu(cpu, mm_cpumask(mm)); cpu_switch_mm(mm->pgd, mm); This causes a problem on ARMv7, where the identity mapping is treated as strongly-ordered leading to architecturally UNPREDICTABLE behaviour of exclusive accesses, such as those used by atomic_inc. This patch re-orders the secondary_start_kernel function so that we switch to swapper before performing any exclusive accesses.

Commit 7f8d4cad1e4e ("Input: extend the number of event (and other) devices") made evdev, joydev and mousedev to embed struct cdev into their respective structures representing input devices. Unfortunately character device structure may outlive the parent structure unless we do not set it up as parent of character device so that it will stay pinned until character device is freed. Also, now that parent structure is pinned while character device exists we do not need to pin and unpin it every time user opens or closes it.

2012-10-22char_dev: pin parent kobjectDmitry Torokhov
In certain cases (for example when a cdev structure is embedded into another object whose lifetime is controlled by a separate kobject) it is beneficial to tie lifetime of another object to the lifetime of character device so that related object is not freed until after char_dev object is freed. To achieve this let's pin kobject's parent when doing cdev_add() and unpin when last reference to cdev structure is being released.

In mke2fs, we only checksum the whole bitmap block and it is right. While in the kernel, we use EXT4_BLOCKS_PER_GROUP to indicate the size of the checksumed bitmap which is wrong when we enable bigalloc. The right size should be EXT4_CLUSTERS_PER_GROUP and this patch fixes it. Also as every caller of ext4_block_bitmap_csum_set and ext4_block_bitmap_csum_verify pass in EXT4_BLOCKS_PER_GROUP(sb)/8, we'd better removes this parameter and sets it in the function itself.

2012-10-20arm64: fix alignment padding in assembly codeMarc Zyngier
An interesting effect of using the generic version of linkage.h is that the padding is defined in terms of x86 NOPs, which can have even more interesting effects when the assembly code looks like this: ENTRY(func1) mov x0, xzr ENDPROC(func1) // fall through ENTRY(func2) mov x0, #1 ret ENDPROC(func2) Admittedly, the code is not very nice. But having code from another architecture doesn't look completely sane either. The fix is to add arm64's version of linkage.h, which causes the insertion of proper AArch64 NOPs.
