ince gfs2 writes the rindex file a block at a time, and releases the
exclusive lock after each block, it is possible that another process
will grab the lock in the middle of the write. Since rindex entries are
not an even divisor of blocks, that other process may see partial
entries. On grows, this is fine. The process can simply ignore the the
partial entires. Previously, the code withdrew when it saw partial
entries. Now it simply ignores them.Signed-off-by: Benjamin Marzinski

The list macros use LIST_POISON1 and LIST_POISON2 as undereferencable
pointers in order to trap erronous use of freed list_heads. Unfortunately
userspace can arrange for those pointers to actually be dereferencable,
potentially turning an oops to an expolit.To avoid this allow architectures (currently x86_64 only) to override
the default values for these pointers with truly-undereferencable values.
This is easy on x86_64 as the virtual address space is large and contains
areas that cannot be mapped.Other 64-bit architectures will likely find similar unmapped ranges.

Update the defconfig for the ASB2303 platform.

Signed-off-by: Linus Torvalds -
Access to the ASB2305's PCnet32 NIC doesn't work correctly because when
the NIC attempts to update the ring buffer flags by DMA, the change to RAM
crops up about 17uS after the interrupt line is asserted. This is almost
certainly due to a bug in the PCI bridge FPGA on that board.We can get around this by making dma_alloc_coherent() put the ring buffer
in the SRAM attached to the PCI bridge rather than in the SDRAM.Signed-off-by: David Howells

Insert PCI root bus resources for the MN10300-based ASB2305 development
kit motherboard. This is required because the CPU's window onto the PCI
bus address space is considerably smaller than the CPU's full address
space and non-PCI devices lie outside of the PCI window that we might want
to access.Without this patch, the PCI root bus uses the platform-level bus
resources, and these are then confined to the PCI window, thus making
platform_device_add() reject devices outside of this window.We also add a reservation for the PCI SRAM region.

Use the generic pci_enable_resources() instead of the arch-specific code.
Unlike this arch-specific code, the generic version:
- checks PCI_NUM_RESOURCES (11), not 6, resources
- skips resources that have neither IORESOURCE_IO nor IORESOURCE_MEM set
- skips ROM resources unless IORESOURCE_ROM_ENABLE is set
- checks for resource collisions with "!r->parent"Signed-off-by: Bjorn Helgaas

gcc 4.2.1 for MN10300 is more agressive than the older gcc in
reordering/moving other insns between an insn that sets flags and an insn
that uses those flags. This leads to trouble with asm statements which
are missing an explicit "cc" clobber. This patch adds the explicit "cc"
clobber to asm statements which do indeed clobber the condition flags.Signed-off-by: Mark Salter

This fixes a signal stack handling problem in the MN10300 arch. When new
threads are cloned with CLONE_VM, they don't inherit the alternate signal
stack. They do share the signal flags, though. When deciding whether to
use an alternate stack, the arch code needs to check to make sure the task
struct contains a valid alternate stack. This patch fixes the MN10300
arch by using the sas_ss_flags() test provided by sched.h rather than the
on_sig_stack() test which is insufficient by itself.Signed-off-by: Mark Salter

The main bug was that 'blk_cleanup_queue()' was called while the block
device could still be in use, for example, because the card was removed
while files were still open.In addition, to be sure that 'mmc_request()' will get called for all new
requests (so it can error them out), the queue is emptied during cleanup.
This is done after the worker thread is stopped to avoid racing with it.Finally, it is not a device error for this to be happening, so quiet the
(sometimes very many) error messages.Signed-off-by: Adrian Hunter

When a card is removed before mmc_blk_probe() has called add_disk(), then
the minor field is uninitialized and has value 0. This caused
mmc_blk_put() to always release devidx 0 even if 0 was still in use. Then
the next mmc_blk_probe() used the first free idx of 0, which oopses in
sysfs, since it is used by another card.Signed-off-by: Anna Lemehova

Commit d899bf7b (procfs: provide stack information for threads) introduced
to show stack information in /proc/{pid}/status. But it cause large
performance regression. Unfortunately /proc/{pid}/status is used ps
command too and ps is one of most important component. Because both to
take mmap_sem and page table walk are heavily operation.If many process run, the ps performance is,

2) Add StackUsage field to /proc/{pid}/status.I only revert (2), because I haven't seen (1) cause regression.

When print-fatal-signals is enabled it's possible to dump any memory
reachable by the kernel to the log by simply jumping to that address from
user space.Or crash the system if there's some hardware with read side effects.
The fatal signals handler will dump 16 bytes at the execution address,
which is fully controlled by ring 3.In addition when something jumps to a unmapped address there will be up to
16 additional useless page faults, which might be potentially slow (and at
least is not very efficient)Fortunately this option is off by default and only there on i386.
But fix it by checking for kernel addresses and also stopping when there's
a page fault.Signed-off-by: Andi Kleen
