ATA: convert GSI to irq on ia64

2007-03-09T18:50:32+00:00

If an ATA drive uses legacy mode, ata driver will choose 14 and 15 as the
fixed irq number.  On ia64 platform, such numbers are GSI and should be
converted to irq vector.

throttle_vm_writeout(): don't loop on GFP_NOFS and GFP_NOIO allocations

2007-03-09T18:50:31+00:00

throttle_vm_writeout() is designed to wait for the dirty levels to subside. 
But if the caller holds IO or FS locks, we might be holding up that writeout.

So change it to take a single nap to give other devices a chance to clean some
memory, then return.

ufs: restore back support of openstep

2007-03-09T18:50:29+00:00

This is a fix of regression, which triggered by ~2.6.16.

Patch with name ufs-directory-and-page-cache-from-blocks-to-pages.patch: in
additional to conversation from block to page cache mechanism added new
checks of directory integrity, one of them that directory entry do not
across directory chunks.

But some kinds of UFS: OpenStep UFS and Apple UFS (looks like these are the
same filesystems) have different directory chunk size, then common
UFSes(BSD and Solaris UFS).

So this patch adds ability to works with variable size of directory chunks,
and set it for ufstype=openstep to right size.

Tested on darwin ufs.

Revert "[PATCH] LOG2: Alter get_order() so that it can make use of ilog2() on a constant"

2007-03-09T18:50:28+00:00

Revert "[PATCH] LOG2: Alter get_order() so that it can make use of ilog2() on a constant"

This reverts commit 39d61db0edb34d60b83c5e0d62d0e906578cc707.

The commit was buggy in multiple ways:
 - the conversion to ilog2() was incorrect to begin with
 - it tested the wrong #defines, so on all architectures but FRV you'd
   never see the bug except for constant arguments.
 - the new "get_order()" macro used its arguments multiple times, and
   didn't even parenthesize them properly
 - despite the comments, it was not true that you could use it for
   constant initializers, since not all architectures even use the
   generic page.h header file.

All of the problems are individually fixable, but it all boils down to:
better just revert it, and re-do it from scratch.

mmc: Power quirk for ENE controllers

mmc: Power quirk for ENE controllers

Support for these devices was broken for 2.6.18-rc1 and later by commit
146ad66eac836c0b976c98f428d73e1f6a75270d, which added voltage level support.

This restores the previous behaviour for these devices by ensuring that when
the voltage is changed, only one write to set the voltage is performed.

It may be that both writes are needed if the voltage is being changed between
two non-zero values or that it's safe to ensure that only one write is done
if the hardware only supports one voltage; I don't know whether either is the
case nor can I test since I have only the one SD reader (1524:0550), and it
supports just the one voltage.

Fix recently introduced problem with shutting down a busy NFS server.

2007-03-09T18:50:21+00:00

When the last thread of nfsd exits, it shuts down all related sockets.
It currently uses svc_close_socket to do this, but that only is
immediately effective if the socket is not SK_BUSY.

If the socket is busy - i.e. if a request has arrived that has not yet
been processes - svc_close_socket is not effective and the shutdown
process spins.

So create a new svc_force_close_socket which removes the SK_BUSY flag
is set and then calls svc_close_socket.

Also change some open-codes loops in svc_destroy to use
list_for_each_entry_safe.
