209ad53 Linus Torvalds 30 October 2006, 01:31:49 UTC Revert "r8169: mac address change support" This reverts commit a2b98a697fa4e7564f78905b83db122824916cf9. As per Guennadi Liakhovetski, the mac address change support code breaks some normal uses (_without_ any address changes), and until it's all sorted out, we're better off without it. Says Francois: "Go revert it. Despite what I claimed, I can not find a third-party confirmation by email that it works elsewhere. It would probably be enough to remove the call to __rtl8169_set_mac_addr() in rtl8169_hw_start() though."

5211e6e Giridhar Pemmasani 29 October 2006, 12:46:55 UTC [PATCH] Fix GFP_HIGHMEM slab panic As reported by Martin J. Bligh <mbligh@google.com>, we let through some non-slab bits to slab allocation through __get_vm_area_node when doing a vmalloc. I haven't been able to reproduce this, although I understand why it happens: vmalloc allocates memory with GFP_KERNEL | __GFP_HIGHMEM and commit 52fd24ca1db3a741f144bbc229beefe044202cac resulted in the same flags are passed down to cache_alloc_refill, causing the BUG. The following patch fixes it. Note that when calling kmalloc_node, I am masking off __GFP_HIGHMEM with GFP_LEVEL_MASK, whereas __vmalloc_area_node does the same with ~(__GFP_HIGHMEM | __GFP_ZERO). IMHO, using GFP_LEVEL_MASK is preferable, but either should fix this problem. Signed-off-by: Giridhar Pemmasani (pgiri@yahoo.com) Cc: Martin J.

0c6cb97 Mel Gorman 28 October 2006, 17:38:59 UTC [PATCH] Calculation fix for memory holes beyong the end of physical memory absent_pages_in_range() made the assumption that users of the arch-independent zone-sizing API would not care about holes beyound the end of physical memory. This was not the case and was "fixed" in a patch called "Account for holes that are outside the range of physical memory". However, when given a range that started before a hole in "real" memory and ended beyond the end of memory, it would get the result wrong. The bug is in mainline but a patch is below. It has been tested successfully on a number of machines and architectures. Additional credit to Keith Mannthey for discovering the problem, helping identify the correct fix and confirming it Worked For Him.

6eac3f9 Vasily Averin 28 October 2006, 17:38:44 UTC [PATCH] missing unused dentry in prune_dcache()? On the the following patch: http://linux.bkbits.net:8080/linux-2.6/gnupatch@449b144ecSF1rYskg3q-SeR2vf88zg # ChangeSet # 2006/06/22 15:05:57-07:00 neilb@suse.de # [PATCH] Fix dcache race during umount # If prune_dcache finds a dentry that it cannot free, it leaves it where it # is (at the tail of the list) and exits, on the assumption that some other # thread will be removing that dentry soon. However as far as I see this comment is not correct: when we cannot take s_umount rw_semaphore (for example because it was taken in do_remount) this dentry is already extracted from dentry_unused list and we do not add it into the list again.

856fc29 Hugh Dickins 28 October 2006, 17:38:43 UTC [PATCH] hugetlb: fix prio_tree unit hugetlb_vmtruncate_list was misconverted to prio_tree: its prio_tree is in units of PAGE_SIZE (PAGE_CACHE_SIZE) like any other, not HPAGE_SIZE (whereas its radix_tree is kept in units of HPAGE_SIZE, otherwise slots would be absurdly sparse). At first I thought the error benign, just calling __unmap_hugepage_range on more vmas than necessary; but on 32-bit machines, when the prio_tree is searched correctly, it happens to ensure the v_offset calculation won't overflow. As it stood, when truncating at or beyond 4GB, it was liable to discard pages COWed from lower offsets; or even to clear pmd entries of preceding vmas, triggering exit_mmap's BUG_ON(nr_ptes).

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.

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.

bbdb396 Martin Bligh 28 October 2006, 17:38:25 UTC [PATCH] Use min of two prio settings in calculating distress for reclaim 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: Martin J.

3bb1a85 Martin Bligh 28 October 2006, 17:38:24 UTC [PATCH] vmscan: Fix temp_priority race 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?

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.

4130a4b David S. Miller 26 October 2006, 05:31:06 UTC [SPARC64]: Fix central/FHC bus handling on Ex000 systems. 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".

452976b Haavard Skinnemoen 24 October 2006, 08:12:45 UTC [PATCH] AVR32: Use __raw MMIO access for internal peripherals 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.

065834a Ben Nizette 24 October 2006, 08:12:43 UTC [PATCH] AVR32: add io{read,write}{8,16,32}{be,} support A number of new drivers require io{read,write}{8,16,32}{be,} family of io operations. These are provided for the AVR32 by this patch in the form of a series of macros. Access to the (memory mapped) io space through these macros is defined to be little endian only as little endian devices (such as PCI) are the main consumer of IO access. If high speed access is required, io{read,write}{16,32}be macros are supplied to perform native big endian access to this io space.
