mm, memcg: partially revert "mm/memcontrol.c: keep local VM counters in sync with the hierarchical ones"

Commit 766a4c19 ("mm/memcontrol.c: keep local VM counters in sync
with the hierarchical ones") effectively decreased the precision of
per-memcg vmstats_local and per-memcg-per-node lruvec percpu counters.

That's good for displaying in memory.stat, but brings a serious
regression into the reclaim process.

One issue I've discovered and debugged is the following:
lruvec_lru_size() can return 0 instead of the actual number of pages in
the lru list, preventing the kernel to reclaim last remaining pages.
Result is yet another dying memory cgroups flooding.  The opposite is
also happening: scanning an empty lru list is the waste of cpu time.

Also, inactive_list_is_low() can return incorrect values, preventing the
active lru from being scanned and freed.  It can fail both because the
size of active and inactive lists are inaccurate, and because the number
of workingset refaults isn't precise.  In other words, the result is
pretty random.

I'm not sure, if using the approximate number of slab pages in
count_shadow_number() is acceptable, but issues described above are
enough to partially revert the patch.

Let's keep per-memcg vmstat_local batched (they are only used for
displaying stats to the userspace), but keep lruvec stats precise.  This
change fixes the dead memcg flooding on my setup.

I've noticed that the "slab" value in memory.stat is sometimes 0, even
if some children memory cgroups have a non-zero "slab" value.  The
following investigation showed that this is the result of the kmem_cache
reparenting in combination with the per-cpu batching of slab vmstats.

At the offlining some vmstat value may leave in the percpu cache, not
being propagated upwards by the cgroup hierarchy.  It means that stats
on ancestor levels are lower than actual.  Later when slab pages are
released, the precise number of pages is substracted on the parent
level, making the value negative.  We don't show negative values, 0 is
printed instead.

To fix this issue, let's flush percpu slab memcg and lruvec stats on
memcg offlining.  This guarantees that numbers on all ancestor levels
are accurate and match the actual number of outstanding slab pages.

The IP datasheet says this controller is compatible with SD Host
Specification Version v4.00.

As it turned out, the ADMA of this IP does not work with 64-bit mode
when it is in the Version 3.00 compatible mode; it understands the
old 64-bit descriptor table (as defined in SDHCI v2), but the ADMA
System Address Register (SDHCI_ADMA_ADDRESS) cannot point to the
64-bit address.

I noticed this issue only after commit bd2e7563 ("dma-contiguous:
use fallback alloc_pages for single pages"). Prior to that commit,
dma_set_mask_and_coherent() returned the dma address that fits in
32-bit range, at least for the default arm64 configuration
(arch/arm64/configs/defconfig). Now the host->adma_addr exceeds the
32-bit limit, causing the real problem for the Socionext SoCs.
(As a side-note, I was also able to reproduce the issue for older
kernels by turning off CONFIG_DMA_CMA.)

Call sdhci_enable_v4_mode() to fix this.

The OCR register defines the supported range of VDD voltages for SD cards.
However, it has turned out that some SD cards reports an invalid voltage
range, for example having bit7 set.

When a host supports MMC_CAP2_FULL_PWR_CYCLE and some of the voltages from
the invalid VDD range, this triggers the core to run a power cycle of the
card to try to initialize it at the lowest common supported voltage.
Obviously this fails, since the card can't support it.

Let's fix this problem, by clearing invalid bits from the read OCR register
for SD cards, before proceeding with the VDD voltage negotiation.

Pull arm64 fixes from Will Deacon:
 "Hot on the heels of our last set of fixes are a few more for -rc7.

  Two of them are fixing issues with our virtual interrupt controller
  implementation in KVM/arm, while the other is a longstanding but
  straightforward kallsyms fix which was been acked by Masami and
  resolves an initialisation failure in kprobes observed on arm64.

   - Fix GICv2 emulation bug (KVM)

   - Fix deadlock in virtual GIC interrupt injection code (KVM)

   - Fix kprobes blacklist init failure due to broken kallsyms lookup"

* tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux:
  KVM: arm/arm64: vgic-v2: Handle SGI bits in GICD_I{S,C}PENDR0 as WI
  KVM: arm/arm64: vgic: Fix potential deadlock when ap_list is long
  kallsyms: Don't let kallsyms_lookup_size_offset() fail on retrieving the first symbol

The de-init routine should be doing the following in order:-
1. Unregister the drm device
2. Shut down the crtcs - failing to do this might cause a connector leakage
See the 'commit 109c4d18 ("drm/arm/malidp: Ensure that the crtcs are
shutdown before removing any encoder/connector")'
3. Disable the interrupts
4. Unbind the components
5. Free up DRM mode_config info

Changes from v1:-
1. Re-ordered the header files inclusion
2. Rebased on top of the latest drm-misc-fixes

Walking the address list of an inet6_dev requires
appropriate locking. Since the called function
siw_listen_address() may sleep, we have to use
rtnl_lock() instead of read_lock_bh().

Also introduces sanity checks if we got a device
from in_dev_get() or in6_dev_get().

The parent image is read only up to the overlap point, the rest of
the buffer should be zeroed.  This snuck in because as it turns out
the overlap test case has not been triggering this code path for
a while now.

In set_secret(), key->tfm is assigned to NULL on line 55, and then
ceph_crypto_key_destroy(key) is executed.

ceph_crypto_key_destroy(key)
  crypto_free_sync_skcipher(key->tfm)
    crypto_free_skcipher(&tfm->base);

This happens to work because crypto_sync_skcipher is a trivial wrapper
around crypto_skcipher: &tfm->base is still 0 and crypto_free_skcipher()
handles that.  Let's not rely on the layout of crypto_sync_skcipher.

This bug is found by a static analysis tool STCheck written by us.

A guest is not allowed to inject a SGI (or clear its pending state)
by writing to GICD_ISPENDR0 (resp. GICD_ICPENDR0), as these bits are
defined as WI (as per ARM IHI 0048B 4.3.7 and 4.3.8).

Make sure we correctly emulate the architecture.

Using strscpy is cleaner, and avoids some problems with
handling maximum length strings.  Linus noticed the
original problem and Aurelien pointed out some additional
problems. Fortunately most of this is SMB1 code (and
in particular the ASCII string handling older, which
is less common).
