The failure to map user-space pages leads to scsi command leak. It can
happens mostly because of user-space daemon bugs (or OOM). This patch
makes tgt just notify a LLD of the failure with sense when
blk_rq_map_user() fails.

This patch simplify the way to notify LLDs of the command completion
and addresses the following sense buffer problems:
- can't handle both data and sense.
- forces user-space to use aligned sense buffer
tgt copies sense_data from userspace to cmnd->sense_buffer (if
necessary), maps user-space pages (if necessary) and then calls
host->transfer_response (host->transfer_data is removed).

scsi tgt breaks up a command into multple scatterlists
if we cannot fit all the data in one. This was because
the block rq helpers did not support large requests and
because we can get a command of any old size so it is
hard to preallocate pages for scatterlist large enough
(we cannot really preallocate pages with the bio map
user path). In 2.6.20, we added large request support to
the block layer helper, blk_rq_map_user. And at LSF,
we talked about increasing SCSI_MAX_PHYS_SEGMENTS for
scsi tgt if we want to support really really :) large
(greater than 256 * PAGE_SIZE in the worst mapping case)
requests.
The only target currently implemented does not even support
the multiple scatterlists stuff and only supports smaller
requests, so this patch just coverts scsi tgt to use
blk_rq_map_user.

For a while now, the block layer has seperated max sectors
and max hw sectors. Software iscsi has no limit so this patch
increases max hw sectors, so we can support large pass through

Dave Miller meantioned that the data buffer in a past
sense fixup patch was not gauranteed to be aligned
properly for ia64. This patch has libiscsi use get_unalinged

of fixing that code for big endien systems so just the sense

- Refactor the command and sense functions so that the actual

- Replace scsi_print_hostbyte() and scsi_print_driverbyte() with
scsi_print_result() which is verbose when CONFIG_SCSI_CONSTANTS is

Recent alterations to the gdth_fill_raw_cmd() path no longer set the
sg_ranz field for zero transfer commands. However, this field is used
lower down in the function to initialise ha->cmd_len to the size of
the firmware packet. If this uninitialised field contains a bogus
value, ha->cmd_len can become much larger than the actual firmware
packet and end up oopsing in gdth_copy_cmd() as it tries to copy this
huge packet to the device (usually because it runs into an unallocated
page).
The fix is to initialise the sg_ranz field to zero at the start of
gdth_fill_raw_cmd().

This fix's an oops during driver load time. mptsas_probe calls
mpt_attach(over in mptbase.c). Inside that call, we read some
manufacturing config pages to setup some defaults. While reading the
config pages, the firmware doesn't complete the reply in time, and we
have a timeout. The timeout results in hardreset handler being called.
The hardreset handler calls all the fusion upper layer driver reset
callback handlers. The mptsas_ioc_reset function is the callback
handler in mptsas.c. So where I'm getting to, is mptsas_ioc_reset is
getting called before scsi_host_alloc is called, and the pointer ioc->sh
is NULL as well as the hostdata.

remove. This patch eliminates the first call; its un-needed.

The overflows could lead to the AGP aperture overlapping the framebuffer are in the card's address space when the latter is located at the very end of th 32 bit address space, which would result in a freeze on X server startup,
probably because the card read commands from the framebuffer instead of from AGP.

Not only does "irq" not even exist in that scope, but we obviously need

Fix atomicity of TIF update in flush_thread() for sparc64
Fixes correctly the race by using *_ti_thread_flag.

arch_ptrace()
ptrace_detach()
ptrace_disable(child);
clear_singlestep(child);

And at the same time, in the child process :
