Commit bdc807871d broke the build
for this config because the sim_defconfig selects CONFIG_HZ=250
but include/asm-ia64/param.h has an ifdef for the simulator to
force HZ to 32. So we ended up with a kernel/timeconst.h set
for HZ=250 ... which then failed the check for the right HZ
value and died with:
Drop the #ifdef magic from param.h and make force CONFIG_HZ=32
directly for the simulator.

Since the sg chaining patches went in, our current value of 255 for
SG_ALL excites chaining on some drivers which cannot support it (and
would thus oops). Redefine SG_ALL to mean no sg table size
preference, but use the single allocation (non chained) limit. This
also helps for drivers that use it to size an internal table.
We'll do an opt in system later where truly chaining supporting
drivers can define their sg_tablesize to be anything up to
SCSI_MAX_SG_CHAIN_ELEMENTS.

The MegaRAID driver's common management module (megaraid_mm.c) creates a
char device used by the management tool "megarc" from LSI Logic (and
possibly other management tools).
In 2.6 with udev, this device doesn't get created because it is not
registered in sysfs.
I first fixed this by registering a class "megaraid_mm", but realized that
this should probably be moved to misc devices, instead of taking up a char
major. This is because only 1 device is used, even if there are multiple
adapters - the minor is never used (the adapter info is in the ioctl block
sent to the driver, not detected based on the minor number as one might
think). So it is a complete waste to have an entire major taken by this.
So it now uses a misc device which I named "megadev0" (the name that megarc
expects), and has a dynamic minor (previoulsy a dynamic major was used).
I have tested this on my own system with the megarc tool, and it works just
as fine as before (only now the device gets created correctly by udev).

struct asc_dvc_var needs overrun buffer to be placed on an 8 byte
boundary. advansys defines struct asc_dvc_var:
struct asc_dvc_var {
...
uchar overrun_buf[ASC_OVERRUN_BSIZE] __aligned(8);
The problem is that struct asc_dvc_var is placed on
shost->hostdata. So if the hostdata is not on an 8 byte boundary, the
advansys crashes. The hostdata is placed on a sizeof(unsigned long)
boundary so the 8 byte boundary is not garanteed with x86_32.
With 2.6.23 and 2.6.24, the hostdata is on an 8 byte boundary by
chance, but with the current git, it's not.
This patch removes overrun_buf static array and use kzalloc.

Since we may not have a pci_dev for the device we need to access, we can't
use pci_read_config_word. But raw_pci_read is an internal implementation
detail; it's better to use the architected pci_bus_read_config_word
interface. Using PCI_DEVFN instead of a mysterious constant helps
reassure everyone that we really do intend to access device 8.

what the write immediately above this is doing -- enabling device 8 to

ide: switch idedisk_prepare_flush() to use REQ_TYPE_ATA_TASKFILE requests
...
broke flush requests.
Allocating IDE command structure on the stack for flush requests is not
a very brilliant idea:
- idedisk_prepare_flush() only prepares the request and it doesn't wait
for it to be completed
- there are can be multiple flush requests queued in the queue
Fix the problem (per hints from James Bottomley) by:
- dynamically allocating ide_task_t instance using kmalloc(..., GFP_ATOMIC)
- adding new taskfile flag (IDE_TFLAG_DYN)
- calling kfree() in ide_end_drive_command() if IDE_TFLAG_DYN is set
(while at it rename 'args' to 'task' and fix whitespace damage)
[ This will be fixed properly before 2.6.25 but this bug is rather
critical and the proper solution requires some more work + testing. ]

problem and testing patches (extra thanks to Sebastian for bisecting

I have reviewed all blk-end-request patches again to confirm whether
there are any similar problems with the last week's ide-cd panic:
http://lkml.org/lkml/2008/1/29/140
And I found a possible similar bug in ide-io change:
ide_end_drive_cmd() could be called for blk_pc_request() which could
have bios. To complete such requests correctly, we need to pass
the actual size of the request.
Otherwise, __blk_end_request() returns 1 because the request still has
bios, and the system will BUG() unnecessarily.
The following patch fixes the bug and should be applied on top of
