On 32-bit machines, mount -t hugetlbfs -o size=4G gave a 0GB filesystem, size=5G gave a 1GB filesystem etc: there's no point in masking size with HPAGE_MASK just before shifting its lower bits away, and since HPAGE_MASK is a UL, that removed all the higher bits of the unsigned long long size.

If __vmalloc is called to allocate memory with GFP_ATOMIC in atomic context, the chain of calls results in __get_vm_area_node allocating memory for vm_struct with GFP_KERNEL, causing the 'sleeping from invalid context' warning. This patch fixes it by passing the gfp flags along so __get_vm_area_node allocates memory for vm_struct with the same flags. Signed-off-by:

Add __GFP_NOWARN flag to calling of __alloc_pages() in __kmalloc_section_memmap(). It can reduce noisy failure message. In ia64, section size is 1 GB, this means that order 8 pages are necessary for each section's memmap. It is often very hard requirement under heavy memory pressure as you know. So, __alloc_pages() gives up allocation and shows many noisy stack traces which means no page for each sections. (Current my environment shows 32 times of stack trace....) But, __kmalloc_section_memmap() calls vmalloc() after failure of it, and it can succeed allocation of memmap. So, its stack trace warning becomes just noisy. I suppose it shouldn't be shown.

When "mdadm --grow --size=xxx" is used to resize an array (use more or less of each device), we check the new siza against the available space in each device. We already have that number recorded in rdev->size, so calculating it is pointless (and wrong in one obscure case). Signed-off-by:

When running several fsx's and other filesystem stress tests, we found cases where an unmapped buffer was still being sent to submit_bh by the ext3 dirty data journaling code. I saw this happen in two ways, both related to another thread doing a truncate which would unmap the buffer in question. Either we would get into journal_dirty_data with a bh which was already unmapped (although journal_dirty_data_fn had checked for this earlier, the state was not locked at that point), or it would get unmapped in the middle of journal_dirty_data when we dropped locks to call sync_dirty_buffer. By re-checking for mapped state after we've acquired the bh state lock, we should avoid these races. If we find a buffer which is no longer mapped, we essentially ignore it, because journal_unmap_buffer has already decided that this buffer can go away. I've also added tracepoints in these two cases, and made a couple other tracepoint changes that I found useful in debugging this. Signed-off-by:

If try_to_free_pages / balance_pgdat are called with a gfp_mask specifying GFP_IO and/or GFP_FS, they will reclaim the requisite number of pages, and the reset prev_priority to DEF_PRIORITY (or to some other high (ie: unurgent) value). However, another reclaimer without those gfp_mask flags set (say, GFP_NOIO) may still be struggling to reclaim pages. The concurrent overwrite of zone->prev_priority will cause this GFP_NOIO thread to unexpectedly cease deactivating mapped pages, thus causing reclaim difficulties. Fix this is to key the distress calculation not off zone->prev_priority, but also take into account the local caller's priority by using min(zone->prev_priority, sc->priority) Signed-off-by:

The temp_priority field in zone is racy, as we can walk through a reclaim path, and just before we copy it into prev_priority, it can be overwritten (say with DEF_PRIORITY) by another reclaimer. The same bug is contained in both try_to_free_pages and balance_pgdat, but it is fixed slightly differently. In balance_pgdat, we keep a separate priority record per zone in a local array. In try_to_free_pages there is no need to do this, as the priority level is the same for all zones that we reclaim from. Impact of this bug is that temp_priority is copied into prev_priority, and setting this artificially high causes reclaimers to set distress artificially low. They then fail to reclaim mapped pages, when they are, in fact, under severe memory pressure (their priority may be as low as 0). This causes the OOM killer to fire incorrectly. From: Andrew Morton <akpm@osdl.org> __zone_reclaim() isn't modifying zone->prev_priority. But zone->prev_priority is used in the decision whether or not to bring mapped pages onto the inactive list. Hence there's a risk here that __zone_reclaim() will fail because zone->prev_priority ir large (ie: low urgency) and lots of mapped pages end up stuck on the active list. Fix that up by decreasing (ie making more urgent) zone->prev_priority as __zone_reclaim() scans the zone's pages. This bug perhaps explains why ZONE_RECLAIM_PRIORITY was created. It should be possible to remove that now, and to just start out at DEF_PRIORITY?

The multithreaded-probing code has a problem: after one initcall level (eg, core_initcall) has been processed, we will then start processing the next level (postcore_initcall) while the kernel threads which are handling core_initcall are still executing. This breaks the guarantees which the layered initcalls previously gave us. IOW, we want to be multithreaded _within_ an initcall level, but not between different levels. Fix that up by causing the probing code to wait for all outstanding probes at one level to complete before we start processing the next level. Cc: Greg KH <greg@kroah.com> Signed-off-by:

Considering below scenario: 1.Unload a PCI device's driver, the device ->current remains in PCI_D0. 2.Do suspend/resume circle. After that, BIOS puts the device to D3. 3.Reload the device driver. The calling pci_set_power_state in the driver can't change the state to D0, as set_power_state thinks the device is already in D0. A bug is reported at http://bugzilla.kernel.org/show_bug.cgi?id=6024 Pat attached a patch at http://marc.theaimsgroup.com/?l=linux-pci&m=114049761428561&w=2 for this issue, but it's lost. As pci_set_power_state can handle D3 -> D0 correctly (restore config space), I simplified Patrick's patch. Signed-off-by:

1) probe_other_fhcs() wants to see only non-central FHC busses, so skip FHCs that don't sit off the root 2) Like SBUS, FHC can lack the appropriate address and size cell count properties, so add an of_busses[] entry and handlers for that. 3) Central FHC irq translator probing was buggy. We were trying to use dp->child in irq_trans_init but that linkage is not setup at this point. So instead, pass in the parent of "dp" and look for the child "fhc" with parent "central".

The read[bwl] and write[bwl] functions are meant for accessing PCI devices. How this is achieved on AVR32 is unknown, as there are no systems with a PCI bridge available yet. On-chip peripheral access, however, should not depend on how we end up implementing PCI access, so using __raw_read[bwl]/__raw_write[bwl] is the right thing to do for on-chip peripherals. This patch converts the drivers for the static memory controller, interrupt controller, PIO controller and system manager to use __raw MMIO access. Signed-off-by:
