The Huawei E173 will normally appear as 12d1:1436 in Linux. But the modem has another mode with different device ID and a slightly different set of descriptors. This is the mode used by Windows like this: 3Modem: USB\VID_12D1&PID_140C&MI_00\6&3A1D2012&0&0000 Networkcard: USB\VID_12D1&PID_140C&MI_01\6&3A1D2012&0&0001 Appli.Inter: USB\VID_12D1&PID_140C&MI_02\6&3A1D2012&0&0002 PC UI Inter: USB\VID_12D1&PID_140C&MI_03\6&3A1D2012&0&0003 All interfaces have the same ff/ff/ff class codes in this mode. Blacklisting the network interface to allow it to be picked up by the network driver.

This patch (as1636) is a partial workaround for a hardware bug affecting OHCI controllers by NVIDIA at least, maybe others too. When the controller retires a Transfer Descriptor, it is supposed to add the TD onto the Done Queue. But sometimes this doesn't happen, with the result that ohci-hcd never realizes the corresponding transfer has finished. Symptoms can vary; a typical result is that USB audio stops working after a while. The patch works around the problem by recognizing that TDs are always processed in order. Therefore, if a later TD is found on the Done Queue than all the earlier TDs for the same endpoint must be finished as well. Unfortunately this won't solve the problem in cases where the missing TD is the last one in the endpoint's queue. A complete fix would require a signficant amount of change to the driver.

Switch to the more efficient generic read implementation. Note that the generic implementation is not required to hold the tty port mutex during resume due to the read-urb free mask and write start flag. Note also that the generic resume implementation will call generic write start if there is a bulk-out end-point, but that nothing will be submitted as the write fifo is not used and is empty.

Revert commit 7f1290f2 ("mm: fix-up zone present pages") That patch tried to fix a issue when calculating zone->present_pages, but it caused a regression on 32bit systems with HIGHMEM. With that change, reset_zone_present_pages() resets all zone->present_pages to zero, and fixup_zone_present_pages() is called to recalculate zone->present_pages when the boot allocator frees core memory pages into buddy allocator. Because highmem pages are not freed by bootmem allocator, all highmem zones' present_pages becomes zero. Various options for improving the situation are being discussed but for now, let's return to the 3.6 code.

Under a particular load on one machine, I have hit shmem_evict_inode()'s BUG_ON(inode->i_blocks), enough times to narrow it down to a particular race between swapout and eviction. It comes from the "if (freed > 0)" asymmetry in shmem_recalc_inode(), and the lack of coherent locking between mapping's nrpages and shmem's swapped count. There's a window in shmem_writepage(), between lowering nrpages in shmem_delete_from_page_cache() and then raising swapped count, when the freed count appears to be +1 when it should be 0, and then the asymmetry stops it from being corrected with -1 before hitting the BUG. One answer is coherent locking: using tree_lock throughout, without info->lock; reasonable, but the raw_spin_lock in percpu_counter_add() on used_blocks makes that messier than expected. Another answer may be a further effort to eliminate the weird shmem_recalc_inode() altogether, but previous attempts at that failed. So far undecided, but for now change the BUG_ON to WARN_ON: in usual circumstances it remains a useful consistency check.

kmap_to_page returns the corresponding struct page for a virtual address of an arbitrary mapping. This works by checking whether the address falls in the pkmap region and using the pkmap page tables instead of the linear mapping if appropriate. Unfortunately, the bounds checking means that PKMAP_ADDR(LAST_PKMAP) is incorrectly treated as a highmem address and we can end up walking off the end of pkmap_page_table and subsequently passing junk to pte_page. This patch fixes the bound check to stay within the pkmap tables.

Jiri Slaby reported the following: (It's an effective revert of "mm: vmscan: scale number of pages reclaimed by reclaim/compaction based on failures".) Given kswapd had hours of runtime in ps/top output yesterday in the morning and after the revert it's now 2 minutes in sum for the last 24h, I would say, it's gone. The intention of the patch in question was to compensate for the loss of lumpy reclaim. Part of the reason lumpy reclaim worked is because it aggressively reclaimed pages and this patch was meant to be a sane compromise. When compaction fails, it gets deferred and both compaction and reclaim/compaction is deferred avoid excessive reclaim. However, since commit c6543459 ("mm: remove __GFP_NO_KSWAPD"), kswapd is woken up each time and continues reclaiming which was not taken into account when the patch was developed. Attempts to address the problem ended up just changing the shape of the problem instead of fixing it. The release window gets closer and while a THP allocation failing is not a major problem, kswapd chewing up a lot of CPU is. This patch reverts commit 83fde0f2 ("mm: vmscan: scale number of pages reclaimed by reclaim/compaction based on failures") and will be revisited in the future.
