12 years agox86: Fix booting with "no387 nofxsr"
Linus Torvalds [Tue, 3 Oct 2006 16:45:46 +0000]
x86: Fix booting with "no387 nofxsr"

Jesper Juhl reported that testing the software math-emulation by forcing
"no387" doesn't work on modern CPU's.

The reason was two-fold:
 - you also need to pass in "nofxsr" to make sure that we not only don't
   touch the old i387 legacy hardware, it also needs to disable the
   modern XMM/FXSR sequences
 - "nofxsr" didn't actually clear the capability bits immediately,
   leaving the early boot sequence still using FXSR until we got to
   the identify_cpu() stage.

This fixes the "nofxsr" flag to take effect immediately on the boot CPU.

[PATCH] pr_debug: check pr_debug() arguments

check pr_debug() arguments

When DEBUG isn't defined pr_debug() is defined away as an empty macro.  By
throwing away the arguments we allow completely incorrect code to build.

Instead let's make it an empty inline which checks arguments and mark it so gcc
can check the format specification.

This results in a seemingly insignificant code size increase.  A x86-64

Paul Clements [Tue, 3 Oct 2006 08:16:01 +0000]
[PATCH] md: use ffz instead of find_first_set to convert multiplier to shift

find_first_set doesn't find the least-significant bit on bigendian machines,
so it is really wrong to use it.

ffs is closer, but takes an 'int' and we have a 'unsigned long'.  So use
ffz(~X) to convert a chunksize into a chunkshift.

[PATCH] md: remove MAX_MD_DEVS which is an arbitrary limit

Once upon a time we needed to fixed limit to the number of md devices,
probably because we preallocated some array.  This need no longer exists, but
we still have an arbitrary limit.

So remove MAX_MD_DEVS and allow as many devices as we can fit into the 'minor'
part of a device number.

Also remove some useless noise at init time (which reports MAX_MD_DEVS) and

It is possible to request a 'check' of an md/raid array where the whole array
is read and consistancies are reported.

This uses the same mechanisms as 'resync' and so reports in the kernel logs
that a resync is being started.  This understandably confuses/worries people.

Also the text in /proc/mdstat suggests a 'resync' is happen when it is just a
check.

This patch changes those messages to be more specific about what is happening.

raid1 read_balance should be modified to prefer devices where

than the '|' branch.  However that should would need some benchmarking first

Paul Clements [Tue, 3 Oct 2006 08:15:49 +0000]
[PATCH] md: new sysfs interface for setting bits in the write-intent-bitmap

Add a new sysfs interface that allows the bitmap of an array to be dirtied.
The interface is write-only, and is used as follows:

echo "1000" > /sys/block/md2/md/bitmap

(dirty the bit for chunk 1000 [offset 0] in the in-memory and on-disk
bitmaps of array md2)

echo "1000-2000" > /sys/block/md1/md/bitmap

(dirty the bits for chunks 1000-2000 in md1's bitmap)

This is useful, for example, in cluster environments where you may need to
combine two disjoint bitmaps into one (following a server failure, after a
secondary server has taken over the array).  By combining the bitmaps on
the two servers, a full resync can be avoided (This was discussed on the
list back on March 18, 2005, "[PATCH 1/2] md bitmap bug fixes" thread).

   not on spares
MD_CHANGE_PENDING
   A superblock update is underway.

We wait for an update to complete by waiting for all flags to be clear.  A
flag can be set at any time, even during an update, without risk that the

[PATCH] dm: use private biosets

I found a problem within device-mapper that occurs in low-mem situations.  It
was found using a mirror target but I think in theory it would hit any setup
that stacks device-mapper devices (like LVM on top of multipath).

Since device-mapper core uses the common fs_bioset in clone_bio(), and a
private, but still global, bio_set in split_bvec() it is possible that the
filesystem and the first level target successfully get bios but the lower
level target doesn't because there is no more memory and the pool was drained
by upper layers.  So the remapping will be stuck forever.  To solve this
device-mapper core needs to use a private bio_set for each device.

[PATCH] dm snapshot: fix freeing pending exception

If a snapshot became invalid while there are outstanding pending_exceptions,
when pending_complete() processes each one it forgets to remove the
corresponding exception from its exception table before freeing it.

Fix this by moving the 'out:' label up one statement so that
remove_exception() is always called.  Then __invalidate_exception() no longer
needs to call it and its 'pe' argument become superfluous.

When suspending a device-mapper device, dm_suspend() sleeps until all

[PATCH] dm: support ioctls on mapped devices: fix with fake file

The new ioctl code passes the wrong file pointer to the underlying device.
No file pointer is available so make a temporary fake one.

ioctl_by_bdev() does set_fs(KERNEL_DS) so it's for ioctls originating
within the kernel and unsuitable here.  We are processing ioctls that
originated in userspace and mapping them to different devices.  Fixing the
existing callers that pass a NULL file struct and consolidating the
fake_file users are separate matters to solve in later patches.

to 1, the output frequency is lower than it should be (divided by 2), giving
