[IA64] perfmon.c: cleanup system-wide context when closed from another cpu
- fix pfm_stop() and pfm_flush_pmds() to correctly cleanup
in case of a system-wide context which is closed while running
from another processor. This was leading to an assertion failure
in pfm_loads_regs() for the next user of the PMU on the monitored

NFSv2: In the NFSv3 RFC, the sattr3 structure passed in the SETATTR
call allows for the client to request that the mtime and/or atime
of an inode be set to the current server time, the given (client)

when you run "touch file" on the client.
The NFSv2 RFC defines no such encoding for the sattr structure.
However Solaris and Irix machine obey a convention where passing
the invalid value mtime.useconds=1000000 means "set both mtime and
atime to the current server time". The convention is documented
in the book "NFS Illustrated" by Brent Callaghan. The patch below
implements this convention for the Linux client and server (hence

NFS: In 2.4, NFS O_DIRECT used the VFS's O_DIRECT logic to provide
direct I/O support for NFS files. The 2.4 VFS O_DIRECT logic was
block based, thus the NFS client had to provide a minimum
allowable blocksize for O_DIRECT reads and writes on NFS files.
For various reasons we chose 512 bytes. In 2.6, there is no
requirement for a minimum blocksize. NFS O_DIRECT reads and
writes can go to any byte at any offset in a file. Thus we revert
the blocksize setting for NFS file systems to the previous
behavior, which was to advertise the "wsize" setting as the
optimal I/O block size. This improves the performance of
applications like 'cp' which use this value as their transfer
size.
This patch also exposes the server's reported disk block size in the
f_frsize of the vfsstat structure.
