    a long idle sleep it drops the update jiffies duty so
    another CPU which is not idle can pick it up and keep

Using the same value for both situations is wrong, as the CPU online
code can see the -1 state when the timer of the newly onlined CPU is
setup. The setup for a newly onlined CPU goes through periodic mode

As its close to the final release just move the hack so it works out,

sparc64: Fix disappearing PCI devices on e3500.

The OF device layer builds properties by matching bus types and
applying 'range' properties as appropriate, up to the root.

The match for "PCI" busses is looking at the 'device_type' property,
and this does work %99 of the time.

But on an E3500 system with a PCI QFE card, the DEC 21153 bridge
sitting above the QFE network interface devices has a 'name' of "pci",
but it completely lacks a 'device_type' property.  So we don't match
it as a PCI bus, and subsequently we end up with no resource values at
all for the devices sitting under that DEC bridge.

bnx2: Promote vector field in bnx2_irq structure from u16 to unsigned int

The bnx2 driver stores/uses the irq value from the pci_dev internally.
But when it stores the irq value, it has been performing an
integer demotion.  Because of the recent changes made to
arch/x86/kernel/io_apic.c, the new method in creating the irq value
(using build_irq_for_pci_dev()) has exposed this bug on x86 systems.

Because of this demotion when calling request_irq() from
bnx2_request_irq(), the driver would get a return code of -EINVAL.
This is because the kernel could not find the requested irq descriptor.
By storing the irq value properly, the kernel can find the correct
irq descriptor and the bnx2 driver can operate normally.

[XFS] Prevent direct I/O from mapping extents beyond eof

With the help from some tracing I found that we try to map extents beyond
eof when doing a direct I/O read. It appears that the way to inform the
generic direct I/O path (ie do_direct_IO()) that we have breached eof is
to return an unmapped buffer from xfs_get_blocks_direct(). This will cause
do_direct_IO() to jump to the hole handling code where is will check for
eof and then abort.

This problem was found because a direct I/O read was trying to map beyond
eof and was encountering delayed allocations. The delayed allocations
beyond eof are speculative allocations and they didn't get converted when
the direct I/O flushed the file because there was only enough space in the
current AG to convert and write out the dirty pages within eof. Note that
xfs_iomap_write_allocate() wont necessarily convert all the delayed
allocation passed to it - it will return after allocating the first extent
- so if the delayed allocation extends beyond eof then it will stay that
way.

[XFS] Fix regression introduced by remount fixup

Logically we would return an error in xfs_fs_remount code to prevent users
from believing they might have changed mount options using remount which
can't be changed.

But unfortunately mount(8) adds all options from mtab and fstab to the
mount arguments in some cases so we can't blindly reject options, but have
to check for each specified option if it actually differs from the
currently set option and only reject it if that's the case.

Until that is implemented we return success for every remount request, and
silently ignore all options that we can't actually change.

16 years ago[XFS] Move memory allocations for log tracing out of the critical path

[XFS] Move memory allocations for log tracing out of the critical path

Memory allocations for log->l_grant_trace and iclog->ic_trace are done on
demand when the first event is logged. In xlog_state_get_iclog_space() we
call xlog_trace_iclog() under a spinlock and allocating memory here can
cause us to sleep with a spinlock held and deadlock the system.

For the log grant tracing we use KM_NOSLEEP but that means we can lose
trace entries. Since there is no locking to serialize the log grant
tracing we could race and have multiple allocations and leak memory.

So move the allocations to where we initialize the log/iclog structures.
Use KM_NOFS to avoid recursing into the filesystem and drop log->l_trace
since it's not even used.
