The header files for the Pb1200/DBAu1200 boards have wrong definition for the IDE interface's decoded range length -- it should be 512 bytes according to what the IDE driver does. In addition, the IDE platform device claims 1 byte too many for its memory resource -- fix the platform code and the IDE driver in accordance. Signed-off-by:

The num_interrupt_in, num_bulk_in, and other checks in the usb-serial code are just wrong, there are too many different devices out there with different numbers of endpoints. We need to just be sticking with the device ids instead of trying to catch this kind of thing. It broke too many different devices. This fixes a large number of usb-serial devices to get them working properly again.

http://bugzilla.kernel.org/show_bug.cgi?id=10124 this change: commit 08f1c192 Author: Muli Ben-Yehuda <muli@il.ibm.com> Date: Sun Jul 22 00:23:39 2007 +0300 x86-64: introduce struct pci_sysdata to facilitate sharing of ->sysdata This patch introduces struct pci_sysdata to x86 and x86-64, and converts the existing two users (NUMA, Calgary) to use it. This lays the groundwork for having other users of sysdata, such as the PCI domains work. The Calgary bits are tested, the NUMA bits just look ok. replaces pcibios_scan_root by pci_scan_bus_parented... but in pcibios_scan_root we have a check about scanned busses.

mb_cache_entry_alloc() was allocating cache entries with GFP_KERNEL. But filesystems are calling this function while holding xattr_sem so possible recursion into the fs violates locking ordering of xattr_sem and transaction start / i_mutex for ext2-4. Change mb_cache_entry_alloc() so that filesystems can specify desired gfp mask and use GFP_NOFS from all of them. Signed-off-by:

As shown by Gurudas Pai recently, we can put hugepages into the surplus state (by echo 0 > /proc/sys/vm/nr_hugepages), even when /proc/sys/vm/nr_overcommit_hugepages is 0. This is actually correct, to allow the original goal (shrink the static pool to 0) to succeed (we are converting hugepages to surplus because they are in use). However, the documentation does not accurately reflect this case. Update it. Signed-off-by:

Since 43cc71ee, the platform modalias is prefixed with "platform:". Add MODULE_ALIAS() to the hotpluggable serial platform drivers, to re-enable auto loading. NOTE that Kconfig for some of these drivers doesn't allow modular builds, and thus doesn't match the driver source's unload support. Presumably their unload code is buggy and/or weakly tested...

There is a bug in the function of cmos_set_alarm. RTC alarm time for October can't be set correctly. For October: 0x0A will be written into the RTC region (MONTH_ALARM) in current kernel. But in fact 0x10 should be written. Wildcards are also not handled correctly. Signed-off-by:

Fix memory corruption and crash on 32-bit x86 systems. If a !PAE x86 kernel is booted on a 32-bit system with more than 4GB of RAM, then we call memory_present() with a start/end that goes outside the scope of MAX_PHYSMEM_BITS. That causes this loop to happily walk over the limit of the sparse memory section map: for (pfn = start; pfn < end; pfn += PAGES_PER_SECTION) { unsigned long section = pfn_to_section_nr(pfn); struct mem_section *ms; sparse_index_init(section, nid); set_section_nid(section, nid); ms = __nr_to_section(section); if (!ms->section_mem_map) ms->section_mem_map = sparse_encode_early_nid(nid) | SECTION_MARKED_PRESENT; 'ms' will be out of bounds and we'll corrupt a small amount of memory by encoding the node ID and writing SECTION_MARKED_PRESENT (==0x1) over it. The corruption might happen when encoding a non-zero node ID, or due to the SECTION_MARKED_PRESENT which is 0x1: mmzone.h:#define SECTION_MARKED_PRESENT (1UL<<0) The fix is to sanity check anything the architecture passes to sparsemem. This bug seems to be rather old (as old as sparsemem support itself), but the exact incarnation depended on random details like configs, which made this bug more prominent in v2.6.25-to-be. An additional enhancement might be to print a warning about ignored or trimmed memory ranges. Signed-off-by:Ingo Molnar <mingo@elte.hu> Tested-by:
