Allow to modify the low-level unbound workqueues cpumask through
sysfs. This is performed by traversing the entire workqueue list
and calling apply_wqattrs_prepare() on the unbound workqueues
with the new low level mask. Only after all the preparation are done,
we commit them all together.
Ordered workqueues are ignored from the low level unbound workqueue
cpumask, it will be handled in near future.
All the (default & per-node) pwqs are mandatorily controlled by
the low level cpumask. If the user configured cpumask doesn't overlap
with the low level cpumask, the low level cpumask will be used for the
wq instead.
The comment of wq_calc_node_cpumask() is updated and explicitly
requires that its first argument should be the attrs of the default
pwq.
The default wq_unbound_cpumask is cpu_possible_mask. The workqueue
subsystem doesn't know its best default value, let the system manager
or the other subsystem set it when needed.
Changed from V8:
merge the calculating code for the attrs of the default pwq together.
minor change the code&comments for saving the user configured attrs.
remove unnecessary list_del().
minor update the comment of wq_calc_node_cpumask().
update the comment of workqueue_set_unbound_cpumask();

When compiling the kernel for GCOV (CONFIG_GCOV_KERNEL,-fprofile-arcs),
gcc allocates a lot of stack space because of the large switch statement
in bpf_jit_insn().
This leads to the following compile warning:
arch/s390/net/bpf_jit_comp.c: In function 'bpf_jit_prog':
arch/s390/net/bpf_jit_comp.c:1144:1: warning: frame size of

half the stack size. The dynamic check would not be reliable.
No check emitted for this function.
arch/s390/net/bpf_jit_comp.c:1144:1: warning: the frame size of 12504
bytes is larger than 1024 bytes [-Wframe-larger-than=]
And indead gcc allocates 12592 bytes of stack space:
# objdump -d arch/s390/net/bpf_jit_comp.o

This reverts commit feba40362b.
Although the principle of this change is good, the implementation has a
few issues.
Firstly we can sometimes fail to abort a syscall because r12 may have
been clobbered by C code if we went down the virtual CPU accounting
path, or if syscall tracing was enabled.
Secondly we have decided that it is safer to abort the syscall even
earlier in the syscall entry path, so that we avoid the syscall tracing
path when we are transactional.
So that we have time to thoroughly test those changes we have decided to
revert this for this merge window and will merge the fixed version in
the next window.
NB. Rather than reverting the selftest we just drop tm-syscall from
TEST_PROGS so that it's not run by default.
