Re: [PATCH 0/2] Allow scsi_prep_fn to occur for retried commands

The following two patches address the hang issue being observed
with Bart's patch on powerpc. The first patch moves the initialization
of jiffies_at_alloc from scsi_init_command to scsi_init_rq, and ensures
we don't zero jiffies_at_alloc in scsi_init_command. The second patch
saves / restores the retry counter in scsi_init_command which lets us
go through scsi_init_command for retries and not forget why we were
there. 

These patches have only been boot tested on my Power machine with ipr
to ensure they fix the issue I was seeing.

Thank you Brian and Bart, for your efforts to fix this bug.

I tested these patches on my PowerPC machine and system booted fine.

allocation time
