For recent ISPs, software during CS_UNDERRUN handling must

the driver to catch this condition, and clear the

9p: attach-per-user
The 9P2000 protocol requires the authentication and permission checks to be
done in the file server. For that reason every user that accesses the file
server tree has to authenticate and attach to the server separately.
Multiple users can share the same connection to the server.
Currently v9fs does a single attach and executes all I/O operations as a
single user. This makes using v9fs in multiuser environment unsafe as it
depends on the client doing the permission checking.
This patch improves the 9P2000 support by allowing every user to attach
separately. The patch defines three modes of access (new mount option
'access'):
- attach-per-user (access=user) (default mode for 9P2000.u)
If a user tries to access a file served by v9fs for the first time, v9fs
sends an attach command to the server (Tattach) specifying the user. If
the attach succeeds, the user can access the v9fs tree.
As there is no uname->uid (string->integer) mapping yet, this mode works
only with the 9P2000.u dialect.
- allow only one user to access the tree (access=<uid>)
Only the user with uid can access the v9fs tree. Other users that attempt
to access it will get EPERM error.
- do all operations as a single user (access=any) (default for 9P2000)
V9fs does a single attach and all operations are done as a single user.
If this mode is selected, the v9fs behavior is identical with the current
one.

depends on this magic offset, or that should care at all about the
particular location of of the .data section (all from vvar.c) in the
vDSO image. If it is really desireable to place .data at 0x900, then it
should be after all the other sections so they fill in the space up to
0x900.
This removes the 0x900 magic and cleans up the output sections generally
in the vDSO linker script. This saves a few hundred bytes in the size
of the vDSO file, bringing it back well under 4kb total so that its vma
only needs one page.

x86: expand /proc/interrupts to include missing vectors, v2
Add missing IRQs and IRQ descriptions to /proc/interrupts.
/proc/interrupts is most useful when it displays every IRQ vector in use by
the system, not just those somebody thought would be interesting.
This patch inserts the following vector displays to the i386 and x86_64
platforms, as appropriate:
rescheduling interrupts
TLB flush interrupts
function call interrupts
thermal event interrupts
threshold interrupts
spurious interrupts
A threshold interrupt occurs when ECC memory correction is occuring at too
high a frequency. Thresholds are used by the ECC hardware as occasional
ECC failures are part of normal operation, but long sequences of ECC
failures usually indicate a memory chip that is about to fail.
Thermal event interrupts occur when a temperature threshold has been
exceeded for some CPU chip. IIRC, a thermal interrupt is also generated
when the temperature drops back to a normal level.
A spurious interrupt is an interrupt that was raised then lowered by the
device before it could be fully processed by the APIC. Hence the apic sees
the interrupt but does not know what device it came from. For this case
the APIC hardware will assume a vector of 0xff.
Rescheduling, call, and TLB flush interrupts are sent from one CPU to
another per the needs of the OS. Typically, their statistics would be used
to discover if an interrupt flood of the given type has been occuring.
AK: merged v2 and v4 which had some more tweaks
AK: replace Local interrupts with Local timer interrupts
AK: Fixed description of interrupt types.

x86: call cache_add_dev() from cache_sysfs_init() explicitly
Call cache_add_dev() from cache_sysfs_init() explicitly, instead of
referencing the CPU notifier callback directly from generic startup
code. Looks cleaner (to me at least) this way, and also makes it
possible to use other tricks to replace __cpuinit{data} annotations, as
recently discussed on this list.

x86: vdso put vars in rodata
This adds a const to the definitions vvar.c makes, so that the vdso_*
variables go into .rodata instead of .data. This is essentially a
cosmetic change, just giving the section headers in the vDSO file more
pleasing flags. These variables are read-only from the perspective of
the vDSO itself and user mode, even though the contents of the DSO image
were adjusted at boot.
