scst: Switch from the cpu_*() to the cpumask_*() API
The cpus_*() functions were deprecated via patch "cpumask:
introduce new API, without changing anything" (November 2008,
commit ID 2d3854a37e8b). Hence switch from the cpus_*() API to
the cpumask_*() API.
This patch has the intended side effect of not adding the "[key]"
property to cpumask sysfs attributes that contain the default
cpumask. The current code namely reads uninitialized bits on
systems where nr_cpu_ids < NR_CPUS because cpus_equal() compares
more bits than those that were set by cpumask_copy().

iSCSI-SCST: A huge improvements in errors recovery and iSCSI RFC complaince as well as performance. Also:
- Fixes and improvements for MaxOutstandingR2T>1
- Flow control tracing added.
- Cleanups
SCST core:
- Now for scst_cmd_init_stage1_done() commands preprocessing_done() is always called before xmit_response(), even in case of abort or error.
- Fixed recently introduced bug, which can lead to sending responses for aborted commands after reply on the corresponding TM command already sent.
- Flow control tracing added.
- Now it is possible to call functions setting commands execution status (e.g., scst_set_cmd_error_status()) several times for the same command. Only the first call will be completed, other calls - ignored.
- All commands are counted and shown in proc/sysfs now. Before only active, i.e. not yet executed commands, were counted and shown there.

for checkpatch errors before being committed.
This patch has been tested as follows:
- Reread the patch below carefully.
- Verified that make -s clean && make -s iscsi scst && make -s -C srpt
still works and does not trigger any compiler warnings.
- Verified that checkpatch does no longer report any errors.
- Checked that the patch generated by generate-kernel-patch still applies
cleanly to the 2.6.25.4 kernel, and that the patched kernel tree still
compiles, installs and boots fine, and that the iscsi-scst, ib_srpt,
scst_disk and scst_vdisk modules still load.
- Tested that iSCSI login/logout still works from a remote system, and that
iSCSI I/O still works.

While all warnings on mismatches between printf-style format strings and
argument lists were fixed on i386 and x86_64, gcc prints a large number of
warnings about mismatches when compiling SCST on ppc64. The patch below
fixes these by casting integer arguments to the type (long long unsigned int)
where appropriate.
This patch has been tested as follows:
- Verified the patch by reading it.
- Checked that make -s clean && make -s iscsi scst && make -s -C srpt did not
trigger any compiler warnings about format strings on i386, x86_64 and ppc.
- Checked that no previously fixed checkpatch warnings were reintroduced in
the patch generated by generate-kernel-patch.
- Checked that the patch generated by generate-kernel-patch still applies
cleanly to the 2.6.25.4 kernel, and that the patched kernel tree still
compiles, installs and boots fine.
Additionally, this patch splits a kernel version preprocessor test from one into two lines, such that
the generate-kernel-patch script can process the version check properly.

The patch below implements the following changes:
- Fixes the remaining warnings reported by checkpatch.pl with regard to the use
of whitespace in C code.
- Adds double qoutes around some #warning messages, such that checkpatch.pl
does no longer try to interprete the text behind the #warning preprocessor
directive.
- Adds an extra conversion to the generate-kernel-patch script that removes
the single space from before goto-labels while generating the kernel patch.
This patch has been tested as follows:
- Verified that svn diff -x -w only shows changes in the #warning preprocessor directives.
- Verified the output of svn diff by reading it.
- Verified that checkpatch.pl does no longer complain on the use of whitespace
(searched through the checkpatch.pl output for the text ' space').
- Verified that the patch generated by the generate-kernel-patch script still
applies cleanly to the 2.6.24 kernel, and that the patched kernel still compiles cleanly.
Please let me know if I have to resubmit parts of this patch to other SCST authors.

One of the Linux kernel patch submission requirements is that source files do
not contain trailing whitespace. The patch below removes trailing whitespace
from .c and .h source files.
Note: it might be more convenient to run the script I used to generate this
patch than to review and apply the patch below. This is how I generated and
verified the patch below:
cat <<EOF >./strip-trailing-whitespace
#!/bin/bash
trap "rm -f $t" EXIT
t=/tmp/temporary-file.$$
for f in "$@"
do
sed 's/[ ]*$//' <"$f" >"$t" && mv "$t" "$f"
done
EOF
chmod a+x ./strip-trailing-whitespace
find -name '*.[ch]' | xargs ./strip-trailing-whitespace
svn diff -x -w

- "RECEIVE DIAGNOSTIC RESULTS" command handling fixed
- Obtaining device queue parameters in scst_obtain_device_parameters() changed to handle NOT READY sense
- Fixed possible dev_cmd_count underflow
- Minor iSCSI-SCST connection closing cleanups and fixes
- Semantic of other *_atomic flags changed a bit. Now they are intended only to allow SCST to optimize execution context. The corresponing functions now can *always* be called on atomic context and, if necessary, should manually determine that using scst_cmd_atomic() function and restart using corresponding *_NEED_THREAD_* return value.
- scst_cmd_get_tgt_resp_flags() and SCST_TSC_FLAG_STATUS flag made obsolete and replaced by scst_cmd_get_is_send_status(). All in-tree drivers updated accordingly
- Cleanup: preprocessing_done_atomic removed, now preprocessing_done() callback always called on thread context
- 64-bit cleanups
- Documented that iscsi-scst-adm is currently broken and explained why
- In user space Makefile's added possibility to specify external linker flags
- Minor performance optimizations
- Other minor cleanups

- Connection close improved to be less agressive and honor TCP TIME_WATE state
- Docs updates
