2009-01-29[CIFS] Make socket retry timeouts consistent between blocking and ↵Steve French
nonblocking cases We have used approximately 15 second timeouts on nonblocking sends in the past, and also 15 second SMB timeout (waiting for server responses, for most request types). Now that we can do blocking tcp sends, make blocking send timeout approximately the same (15 seconds). Signed-off-by: Steve French <sfrench@us.ibm.com>

2009-01-29[CIFS] revalidate parent inode when rmdir done within that directorySteve French
When a search is pending of a parent directory, and a child directory within it is removed, we need to reset the parent directory's time so that we don't reuse the (now stale) search results.

2009-01-29cifs: turn smb_send into a wrapper around smb_sendvJeff Layton
cifs: turn smb_send into a wrapper around smb_sendv Rename smb_send2 to smb_sendv to make it consistent with kernel naming conventions for functions that take a vector. There's no need to have 2 functions to handle sending SMB calls. Turn smb_send into a wrapper around smb_sendv. This also allows us to properly mark the socket as needing to be reconnected when there's a partial send from smb_send. Also, in practice we always use the address and noblocksnd flag that's attached to the TCP_Server_Info. There's no need to pass them in as separate args to smb_sendv.

2009-01-28ACPI: remove BM_RLD access from idle entry pathLen Brown
It is true that BM_RLD needs to be set to enable bus master activity to wake an older chipset (eg PIIX4) from C3. This is contrary to the erroneous wording the ACPI 2.0, 3.0 specifications that suggests that BM_RLD is an indicator rather than a control bit. ACPI 1.0's correct wording should be restored in ACPI 4.0: http://www.acpica.org/bugzilla/show_bug.cgi?id=689 But the kernel should not have to clear BM_RLD when entering a non C3-type state just to set it again when entering a C3-type C-state. We should be able to set BM_RLD at boot time and leave it alone -- removing the overhead of accessing this IO register from the idle entry path. Signed-off-by: Len Brown <len.brown@intel.com>

2009-01-28Btrfs: fix readdir on 32 bit machinesChris Mason
After btrfs_readdir has gone through all the directory items, it sets the directory f_pos to the largest possible int. This way applications that mix readdir with creating new files don't end up in an endless loop finding the new directory items as they go. It was a workaround for a bug in git, but the assumption was that if git could make this looping mistake than it would be a common problem. The largest possible int chosen was INT_LIMIT(typeof(file->f_pos), and it is possible for that to be a larger number than 32 bit glibc expects to come out of readdir. This patches switches that to INT_LIMIT(off_t), which should keep applications happy on 32 and 64 bit machines. Signed-off-by: Chris Mason <chris.mason@oracle.com>

2009-01-28ieee1394: sbp2: don't assume zero model_id or firmware_revision if there is noneStefan Richter
This makes sbp2 behave more like firewire-sbp2 which reports 0xff000000 as immediate value if there are no unit directory entries for model_id or firmware_revision. It does not reduce matches with the currently existing quirks table; the only zero entry there is for a device which actually does have a zero model_id. It only changes how model_id and firmware_revision are logged if they are missing. Other functionally unrelated changes: The model_id member of quirks list entries is renamed to model; the value (but not the effect) of SBP2_ROM_VALUE_WILDCARD is changed. Now this part of the source is identical with firewire-sbp2 for easier maintenance. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

2009-01-28ACPI: remove locking from PM1x_STS register readsLen Brown
PM1a_STS and PM1b_STS are twins that get OR'd together on reads, and all writes are repeated to both. The fields in PM1x_STS are single bits only, there are no multi-bit fields. So it is not necessary to lock PM1x_STS reads against writes because it is impossible to read an intermediate value of a single bit. It will either be 0 or 1, even if a write is in progress during the read. Reads are asynchronous to writes no matter if a lock is used or not. Signed-off-by: Len Brown <len.brown@intel.com>

2009-01-28[ARM] 5366/1: fix shared memory coherency with VIVT L1 + L2 cachesNicolas Pitre
When there are multiple L1-aliasing userland mappings of the same physical page, we currently remap each of them uncached, to prevent VIVT cache aliasing issues. (E.g. writes to one of the mappings not being immediately visible via another mapping.) However, when we do this remapping, there could still be stale data in the L2 cache, and an uncached mapping might bypass L2 and go straight to RAM. This would cause reads from such mappings to see old data (until the dirty L2 line is eventually evicted.) This issue is solved by forcing a L2 cache flush whenever the shared page is made L1 uncacheable. Ideally, we would make L1 uncacheable and L2 cacheable as L2 is PIPT. But Feroceon does not support that combination, and the TEX=5 C=0 B=0 encoding for XSc3 doesn't appear to work in practice.
