Queueing a per-sta work item from the tx free path can become very expensive
under load. This work is only supposed to pull rate control stats every
second and deal with rate control changes.
Additionally, the rate control update code was wrong, because it was
confusing bit masks and bit numbers in test_bit.
Fix this by introducing a dedicated device work item for rate control
updates, and by polling station stats from the phy mac work.
Stations requiring polling or rate control updates are added to lists
protected by dev->sta_poll_lock.

PowerPC allmodconfig often fails to build as follows:
LD .tmp_vmlinux.kallsyms1

LD .tmp_vmlinux.kallsyms2
KSYM .tmp_vmlinux.kallsyms2.o
LD .tmp_vmlinux.kallsyms3
KSYM .tmp_vmlinux.kallsyms3.o
LD vmlinux
SORTTAB vmlinux
SYSMAP System.map
Inconsistent kallsyms data
Try make KALLSYMS_EXTRA_PASS=1 as a workaround
make[2]: *** [../Makefile:1162: vmlinux] Error 1
Setting KALLSYMS_EXTRA_PASS=1 does not help.
This is caused by the compiler inserting stubs such as *.long_branch.*
and *.plt_branch.*
$ powerpc-linux-nm -n .tmp_vmlinux.kallsyms2
[ snip ]
c00000000210c010 t 00000075.plt_branch.da9:19
c00000000210c020 t 00000075.plt_branch.1677:5

c00000000210c044 t 00000075.plt_branch.free_initrd_mem
...
Actually, the problem mentioned in scripts/link-vmlinux.sh comments;
"In theory it's possible this results in even more stubs, but unlikely"
is happening here, and ends up with another kallsyms step required.
scripts/kallsyms.c already ignores various compiler stubs. Let's do
similar to make kallsysms for PowerPC always succeed in 2 steps.

Commit 09854ba94c ("mm: do_wp_page() simplification") reorganized all
the code around the page re-use vs copy, but in the process also moved
the final unlock_page() around to after the wp_page_reuse() call.
That normally doesn't matter - but it means that the unlock_page() is
now done after releasing the page table lock. Again, not a big deal,
you'd think.
But it turns out that it's very wrong indeed, because once we've
released the page table lock, we've basically lost our only reference to
the page - the page tables - and it could now be free'd at any time. We
do hold the mmap_sem, so no actual unmap() can happen, but madvise can
come in and a MADV_DONTNEED will zap the page range - and free the page.
So now the page may be free'd just as we're unlocking it, which in turn
will usually trigger a "Bad page state" error in the freeing path. To
make matters more confusing, by the time the debug code prints out the
page state, the unlock has typically completed and everything looks fine
again.
This all doesn't happen in any normal situations, but it does trigger
with the dirtyc0w_child LTP test. And it seems to trigger much more
easily (but not expclusively) on s390 than elsewhere, probably because
s390 doesn't do the "batch pages up for freeing after the TLB flush"
that gives the unlock_page() more time to complete and makes the race
harder to hit.

Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
Previously, when you double-clicked the "int", "hex", or "string" menus,
a line-edit gadget showed up to allow you to input the value, which
looked clumsy.
Also, it was buggy; the editor opened even if the config option was not
editable. For example, just try to double-click CC_VERSION_TEXT, which
has no prompt.
This commit sub-classes QStyleItemDelegate to allow users to edit
"int", "hex", "string" menus in-place. Just double-click (or press
the F2 key) in the data column. Then, an editor widget is placed on
top of the item view.
The two methods are overridden:
createEditor - process only when the data column is being accessed
and the menu is visible. Otherwise, return nullptr to disallow editing.
setModelData - take the new data from the editor, and set it to the
addressed symbol. If it was successful, update all the list windows.
Otherwise, (the reason for the failure is possibly the input data was
out of range), set the old value back to the editor.
