The back and forth typecasting of restart_block->args is horrible. We
added a separate union member for futex already. Do the same for

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: Sergei Shtylyov

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.Cc: Oliver Neukum

commit 08f1c192c3c32797068bfe97738babb3295bbf42
Author: Muli Ben-Yehuda
Date: Sun Jul 22 00:23:39 2007 +0300x86-64: 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: Jan Kara

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: Nishanth Aravamudan

Since 43cc71eed1250755986da4c0f9898f9a635cb3bf, the platform
modalias is prefixed with "platform:". Add MODULE_ALIAS() to the
hotpluggable platform LED drivers, to re-enable auto loading.[dbrownell@users.sourceforge.net: more drivers, registration fixes]

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: Zhao Yakui

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<
