Add a default poll idle state with 0 latency. Provides an option to users
to use poll_idle by using 0 as the latency requirement.Signed-off-by: Venkatesh Pallipadi

Show C1 idle time in /sysfs cpuidle interface. C1 idle time may not
be entirely accurate in all cases. It includes the time spent
in the interrupt handler after wakeup with "hlt" based C1. But, it will
be accurate with "mwait" based C1.Signed-off-by: Venkatesh Pallipadi
Signed-off-by: Len Brown -
Add MWAIT idle for C1 state instead of halt, on platforms that support
C1 state with MWAIT.Renames cx->space_id to something more appropriate.

acpi_safe_halt() needs interrupts to be disabled for atomic
need_resched check and safe halt. Otherwise we may miss an
interrupt and go into halt.acpi_safe_halt() also does not enable interrupts on all return paths.
So the callers should handle enable and disable interrupts around it.

This merges the mux.c (including the connection interface) with trans_fd
in preparation for transport API changes. Ultimately, trans_fd will need
to be rewritten to clean it up and simplify the implementation, but this
reorganization is viewed as the first step.Signed-off-by: Eric Van Hensbergen

Request from rusty:
Just cleaning up patches for 2.6.25 merge, and noticed that
net/9p/trans_virtio.c doesn't have a remove function. This will crash when
removing the module (console doesn't have one because it can't really be
removed).Signed-off-by: Eric Van Hensbergen

When booting from v9fs, down_interruptible in p9_idpool_get() triggered a BUG
as it was being called with IRQs disabled. A spinlock seems like the right
thing to be using since the idr functions go out of their way not to sleep.This patch eliminates the BUG by converting the semaphore to a spinlock.

v9fs was allowing writable mmap which could lead to kernel BUG() cases.
This sets the mmap function to generic_file_readonly_mmap which (correctly)
returns an error to applications which open mmap for writing.Signed-off-by: Eric Van Hensbergen
-
GDM gets unhappy if /var/gdm doesn't have the sticky bit set. This patch adds
support for the sticky bit in much the same way setuid/setgid is supported.With this patch, I can launch X from a v9fs rootfs (although I quickly run out
of fds in the server once gnome starts up).Signed-off-by: Anthony Liguori

This fixes a poorly placed spinlock which could result in a
soft lockup condition.Signed-off-by: Eric Van Hensbergen
-
When a new user attached at a directory other than the root, he would end
up in the parent directory of the cwd. This was due to a logic error in
the code which attaches the user at the mount point and walks back to the
cwd. This patch fixes that.Signed-off-by: Eric Van Hensbergen

This replaces the console-based virto client with a block-based
client using a single request queue.Signed-off-by: Eric Van Hensbergen
-
Add a new transport function which allows a cut-thru directly to
the transport instead of processing request through the mux if the
cut-thru exists.Signed-off-by: Eric Van Hensbergen
