Fix the ps3_set_bookmark() routine of the PS3 logical performance
monitor driver.

To properly set a performance monitor bookmark the Cell processor
requires no instruction branches near the setting of the bookmark
SPR.  Testing showed that the use of the db10cyc instruction did
not work correctly.  This change replaces the db10cyc instruction
with 10 nop instructions.

select strikes again. ipwireless selects PPP which in turn tries to select
SLHC, both of which are technically "protected" by an if NETDEVICES
in drivers/net/Kconfig. This leads to .config hilarity, with net suddenly
ending up in the SCSI menu:

	#
	# SCSI device support
	#
	# CONFIG_SCSI_DMA is not set
	# CONFIG_SCSI_NETLINK is not set
	CONFIG_PPP=y
	# CONFIG_PHONE is not set

Curiously the SLHC select from PPP doesn't seem to happen, as there's no
CONFIG_SLHC=y (only CONFIG_PPP=y gets set) -- Kconfig bug? Caught with a
randconfig.

unconditionally fills in a 32-bit integer return value regardless of the

So claiming to take a "void *" is wrong, as is passing in a pointer to

It looks like there's been a bug in the module parameter setup forever.
The upshot doesn't really matter, because even if no parameters are ever
set, we just call sym53c416_setup() three times, but the zero values in
the arrays eventually cause nothing to happen.  Unfortunately gcc has
started to notice this now too:

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.
