2013-09-17HSI: omap_ssi: Introducing OMAP SSI driverCarlos Chinea
Introduces the OMAP SSI driver in the kernel. The Synchronous Serial Interface (SSI) is a legacy version of HSI. As in the case of HSI, it is mainly used to connect Application engines (APE) with cellular modem engines (CMT) in cellular handsets. It provides a multichannel, full-duplex, multi-core communication with no reference clock. The OMAP SSI block is capable of reaching speeds of 110 Mbit/s.

2013-09-15partitions/efi: loosen check fot pmbr size in lbaDavidlohr Bueso
Matt found that commit 27a7c642174e ("partitions/efi: account for pmbr size in lba") caused his GPT formatted eMMC device not to boot. The reason is that this commit enforced Linux to always check the lesser of the whole disk or 2Tib for the pMBR size in LBA. While most disk partitioning tools out there create a pMBR with these characteristics, Microsoft does not, as it always sets the entry to the maximum 32-bit limitation - even though a drive may be smaller than that[1]. Loosen this check and only verify that the size is either the whole disk or 0xFFFFFFFF. No tool in its right mind would set it to any value other than these.

2013-09-13vfs: fix dentry LRU list handling and nr_dentry_unused accountingLinus Torvalds
The LRU list changes interacted badly with our nr_dentry_unused accounting, and even worse with the new DCACHE_LRU_LIST bit logic. This introduces helper functions to make sure everything follows the proper dcache d_lru list rules: the dentry cache is complicated by the fact that some of the hotpaths don't even want to look at the LRU list at all, and the fact that we use the same list entry in the dentry for both the LRU list and for our temporary shrinking lists when removing things from the LRU. The helper functions temporarily have some extra sanity checking for the flag bits that have to match the current LRU state of the dentry. We'll remove that before the final 3.12 release, but considering how easy it is to get wrong, this first cleanup version has some very particular sanity checking.

2013-09-13cifs: Avoid calling unlock_page() twice in cifs_readpage() when using fscacheSachin Prabhu
When reading a single page with cifs_readpage(), we make a call to fscache_read_or_alloc_page() which once done, asynchronously calls the completion function cifs_readpage_from_fscache_complete(). This completion function unlocks the page once it has been populated from cache. The module then attempts to unlock the page a second time in cifs_readpage() which leads to warning messages. In case of a successful call to fscache_read_or_alloc_page() we should skip the second unlock_page() since this will be called by the cifs_readpage_from_fscache_complete() once the page has been populated by fscache. With the modifications to cifs_readpage_worker(), we will need to re-grab the page lock in cifs_write_begin(). The problem was first noticed when testing new fscache patches for cifs. https://bugzilla.redhat.com/show_bug.cgi?id=1005737 Signed-off-by: Sachin Prabhu <sprabhu@redhat.com> Reviewed-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Steve French <smfrench@gmail.com>

2013-09-13MIPS: DECstation I/O ASIC DMA interrupt handling fixMaciej W. Rozycki
This change complements commit d0da7c002f7b2a93582187a9e3f73891a01d8ee4 and brings clear_ioasic_irq back, renaming it to clear_ioasic_dma_irq at the same time, to make I/O ASIC DMA interrupts functional. Unlike ordinary I/O ASIC interrupts DMA interrupts need to be deasserted by software by writing 0 to the respective bit in I/O ASIC's System Interrupt Register (SIR), similarly to how CP0.Cause.IP0 and CP0.Cause.IP1 bits are handled in the CPU (the difference is SIR DMA interrupt bits are R/W0C so there's no need for an RMW cycle). Otherwise the handler is reentered over and over again. The only current user is the DEC LANCE Ethernet driver and its extremely uncommon DMA memory error handler that does not care when exactly the interrupt is cleared. Anticipating the use of DMA interrupts by the Zilog SCC driver this change however exports clear_ioasic_dma_irq for device drivers to choose the right application-specific sequence to clear the request explicitly rather than calling it implicitly in the .irq_eoi handler of `struct irq_chip'. Previously these interrupts were cleared in the .end handler of the said structure, before it was removed. Signed-off-by: Maciej W.

2013-09-13MIPS: DECstation HRT initialization rearrangementMaciej W. Rozycki
Not all I/O ASIC versions have the free-running counter implemented, an early revision used in the 5000/1xx models aka 3MIN and 4MIN did not have it. Therefore we cannot unconditionally use it as a clock source. Fortunately if not implemented its register slot has a fixed value so it is enough if we check for the value at the end of the calibration period being the same as at the beginning. This also means we need to look for another high-precision clock source on the systems affected. The 5000/1xx can have an R4000SC processor installed where the CP0 Count register can be used as a clock source. Unfortunately all the R4k DECstations suffer from the missed timer interrupt on CP0 Count reads erratum, so we cannot use the CP0 timer as a clock source and a clock event both at a time. However we never need an R4k clock event device because all DECstations have a DS1287A RTC chip whose periodic interrupt can be used as a clock source. This gives us the following four configuration possibilities for I/O ASIC DECstations: 1. No I/O ASIC counter and no CP0 timer, e.g. R3k 5000/1xx (3MIN). 2. No I/O ASIC counter but the CP0 timer, i.e. R4k 5000/150 (4MIN). 3. The I/O ASIC counter but no CP0 timer, e.g. R3k 5000/240 (3MAX+). 4. The I/O ASIC counter and the CP0 timer, e.g. R4k 5000/260 (4MAX+). For #1 and #2 this change stops the I/O ASIC free-running counter from being installed as a clock source of a 0Hz frequency. For #2 it also arranges for the CP0 timer to be used as a clock source rather than a clock event device, because having an accurate wall clock is more important than a high-precision interval timer. For #3 there is no change. For #4 the change makes the I/O ASIC free-running counter installed as a clock source so that the CP0 timer can be used as a clock event device. Unfortunately the use of the CP0 timer as a clock event device relies on a succesful completion of c0_compare_interrupt. That never happens, because while waiting for a CP0 Compare interrupt to happen the function spins in a loop reading the CP0 Count register. This makes the CP0 Count erratum trigger reliably causing the interrupt waited for to be lost in all cases. As a result #4 resorts to using the CP0 timer as a clock source as well, just as #2. However we want to keep this separate arrangement in case (hope) c0_compare_interrupt is eventually rewritten such that it avoids the erratum. Signed-off-by: Maciej W.

git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending Pull SCSI target updates from Nicholas Bellinger: "Lots of activity again this round for I/O performance optimizations (per-cpu IDA pre-allocation for vhost + iscsi/target), and the addition of new fabric independent features to target-core (COMPARE_AND_WRITE + EXTENDED_COPY). The main highlights include: - Support for iscsi-target login multiplexing across individual network portals - Generic Per-cpu IDA logic (kent + akpm + clameter) - Conversion of vhost to use per-cpu IDA pre-allocation for descriptors, SGLs and userspace page pointer list - Conversion of iscsi-target + iser-target to use per-cpu IDA pre-allocation for descriptors - Add support for generic COMPARE_AND_WRITE (AtomicTestandSet) emulation for virtual backend drivers - Add support for generic EXTENDED_COPY (CopyOffload) emulation for virtual backend drivers. - Add support for fast memory registration mode to iser-target (Vu) The patches to add COMPARE_AND_WRITE and EXTENDED_COPY support are of particular significance, which make us the first and only open source target to support the full set of VAAI primitives.

2013-09-12mm, thp: count thp_fault_fallback anytime thp fault failsDavid Rientjes
Currently, thp_fault_fallback in vmstat only gets incremented if a hugepage allocation fails. If current's memcg hits its limit or the page fault handler returns an error, it is incorrectly accounted as a successful thp_fault_alloc. Count thp_fault_fallback anytime the page fault handler falls back to using regular pages and only count thp_fault_alloc when a hugepage has actually been faulted.
