* [PATCH] powerpc iseries link error in allmodconfigJudith Lebzelter2006-12-301-0/+2

* [PATCH] getting rid of all casts of k[cmz]alloc() callsRobert P. J. Day2006-12-1311-16/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Run this: #!/bin/sh for f in $(grep -Erl "\([^\)]*\) *k[cmz]alloc" *) ; do echo "De-casting $f..." perl -pi -e "s/ ?= ?\([^\)]*\) *(k[cmz]alloc) *\(/ = \1\(/" $f done And then go through and reinstate those cases where code is casting pointers to non-pointers. And then drop a few hunks which conflicted with outstanding work.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | megaraid's MMIO RD*/WR* macros directly call readl() and writel() with an 'unsigned long' argument. This throws a warning, but is otherwise OK because the 'unsigned long' is really the result of ioremap(). This setup is also OK because the variable can hold an ioremap cookie /or/ a PCI I/O port (PIO). However, to fix the warning thrown when readl() and writel() are passed an unsigned long cookie, I introduce 'void __iomem *mmio_base', holding the same value as 'base'. This will silence the warnings, and also cause an oops whenever these MMIO-only functions are ever accidentally passed an I/O address.

Note, per the last review we moved almost all the fields we added to the scsi_cmnd to our internal data structure which we are going to try and kill off when we can replace it with support from other parts of the kernel. The one field we left on was the offset variable. This is needed to handle the case where the target gets request that is so large that it cannot execute it in one dma operation. So max_secotors or a segment limit may limit the size of the transfer. In this case our tgt core code will break up the command into managable transfers and send them to the LLD one at a time. The offset is then used to tell the LLD where in the command we are at. Is there another field on the scsi_cmd for that?

| | * [SCSI] qla2xxx: defer topology discovery to DPC thread during initialization.Andrew Vasquez2006-11-222-107/+16

Benefits: user does not have to wait 20+ seconds in case the FC cable is unplugged during driver load, code consolidation (removal of redundant link negotiation logic during initialize_adaoter()), and finilly, the driver no longer needs to defer the fc_remote_port_add() calls to hold off lun-scanning prior to returning from the probe() function.
