I found a serious performance bug in packet schedulers using hrtimers.

sch_htb and sch_fq are definitely impacted by this problem.

We constantly rearm high resolution timers if some packets are throttled
in one (or more) class, and other packets are flying through qdisc on
another (non throttled) class.

hrtimer_start() does not have the mod_timer() trick of doing nothing if
expires value does not change :

	if (timer_pending(timer) &&
            timer->expires == expires)
                return 1;

This issue is particularly visible when multiple cpus can queue/dequeue
packets on the same qdisc, as hrtimer code has to lock a remote base.

I used following fix :

1) Change htb to use qdisc_watchdog_schedule_ns() instead of open-coding
it.

2) Cache watchdog prior expiration. hrtimer might provide this, but I
prefer to not rely on some hrtimer internal.

One timer, whose handler keeps reading on MMIO register for EEH
core to detect error in time, is started when the PCI device driver
is loaded. MMIO register can't be accessed during PE reset in EEH
recovery. Otherwise, the unexpected recursive error is triggered.
The timer isn't closed that time if the interface isn't brought
up. So the unexpected recursive error is seen during EEH recovery
when the interface is down.

This avoids the unexpected recursive EEH error by closing the timer
in qlge_io_error_detected() before EEH PE reset unconditionally. The
timer is started unconditionally after EEH PE reset in qlge_io_resume().
Also, the timer should be closed unconditionally when the device is
removed from the system permanently in qlge_io_error_detected().

Follow-up to commit e27f4a94 ("bpf: Use mount_nodev not mount_ns
to mount the bpf filesystem"), which removes the FS_USERNS_MOUNT flag.

The original idea was to have a per mountns instance instead of a
single global fs instance, but that didn't work out and we had to
switch to mount_nodev() model. The intent of that middle ground was
that we avoid users who don't play nice to create endless instances
of bpf fs which are difficult to control and discover from an admin
point of view, but at the same time it would have allowed us to be
more flexible with regard to namespaces.

Therefore, since we now did the switch to mount_nodev() as a fix
where individual instances are created, we also need to remove userns
mount flag along with it to avoid running into mentioned situation.
I don't expect any breakage at this early point in time with removing
the flag and we can revisit this later should the requirement for
this come up with future users. This and commit e27f4a94 have
been split to facilitate tracking should any of them run into the
unlikely case of causing a regression.

Commit fa50d974 ("ipv4: Namespaceify ip_default_ttl sysctl knob")
moves the default TTL assignment, and as side-effect IPv4 TTL now
has a default value only if sysctl support is enabled (CONFIG_SYSCTL=y).

The sysctl_ip_default_ttl is fundamental for IP to work properly,
as it provides the TTL to be used as default. The defautl TTL may be
used in ip_selected_ttl, through the following flow:

  ip_select_ttl
    ip4_dst_hoplimit
      net->ipv4.sysctl_ip_default_ttl

This commit fixes the issue by assigning net->ipv4.sysctl_ip_default_ttl
in net_init_net, called during ipv4's initialization.

Without this commit, a kernel built without sysctl support will send
all IP packets with zero TTL (unless a TTL is explicitly set, e.g.
with setsockopt).

Given a similar issue might appear on the other knobs that were
namespaceify, this commit also moves them.

The sk_err and sk_err_soft fields are positive errno values and
userspace applications rely on this when using getsockopt(SO_ERROR).

ATM code places an -errno into sk_err_soft in sigd_send() and returns it
from svc_addparty()/svc_dropparty().

Although I am not familiar with ATM code I came to this conclusion
because:

1. sigd_send() msg->type cases as_okay and as_error both have:

   sk->sk_err = -msg->reply;

   while the as_addparty and as_dropparty cases have:

   sk->sk_err_soft = msg->reply;

   This is the source of the inconsistency.

2. svc_addparty() returns an -errno and assumes sk_err_soft is also an
   -errno:

       if (flags & O_NONBLOCK) {
           error = -EINPROGRESS;
           goto out;
       }
       ...
       error = xchg(&sk->sk_err_soft, 0);
   out:
       release_sock(sk);
       return error;

   This shows that sk_err_soft is indeed being treated as an -errno.

This patch ensures that sk_err_soft is always a positive errno.

   - Soumya PN sent me a clean up patch to not disable interrupts when
     taking the tasklist_lock for read, as it's unnecessary because that
     lock is never taken for write in irq context.

   - Newer gcc's can cause the jump in the function_graph code to the
     global ftrace_stub label to be a short jump instead of a long one.
     As that jump is dynamically converted to jump to the trace code to
     do function graph tracing, and that conversion expects a long jump
     it can corrupt the ftrace_stub itself (it's directly after that
     call).  One way to prevent gcc from using a short jump is to
     declare the ftrace_stub as a weak function, which we do here to

Commit b3c1be1b ("base: isa: Remove X86_32 dependency") made ISA
support available on x86-64 too.  That's not right - while there are
some LPC-style devices that might be useful still and be based on
ISA-like IP blocks, that is *not* an excuse to try to enable any random
legacy drivers.

Such drivers should be individually enabled and made to perhaps depend
on ISA_DMA_API instead (which we have continued to support on x86-64).
Or we could add another "ISA_XYZ_API" that we support that doesn't
enable random old drivers that aren't even 64-bit clean nor do we have
any test coverage for.

Turning off ISA will now also turn off some drivers that have been
marked as depending on it as part of this series, and that used to work
on modern platforms.

See for example commits ad7afc38..cc736607, which may also need
to be reverted.

This commit means that the warnings that came in due to enabling ISA
widely are now gone again.

Pull clk updates from Stephen Boyd:
 "It's the usual big pile of driver updates and additions, but we do
  have a couple core changes in here as well.

  Core:

   - CLK_IS_CRITICAL support has been added.  This should allow drivers
     to properly express that a certain clk should stay on even if their
     prepare/enable count drops to 0 (and in turn the parents of these
     clks should stay enabled).

   - A clk registration API has been added, clk_hw_register(), and an OF
     clk provider API has been added, of_clk_add_hw_provider().  These
     APIs have been put in place to further split clk providers from clk
     consumers, with the goal being to have clk providers never deal
     with struct clk pointers at all.  Conversion of provider drivers is
     on going.  clkdev has also gained support for registering clk_hw
     pointers directly so we can convert drivers that don't use
     devicetree.

  New Drivers:

   - Marvell ap806 and cp110 system controllers (with clks inside!)
   - Hisilicon Hi3519 clock and reset controller
   - Axis ARTPEC-6 clock controllers
   - Oxford Semiconductor OXNAS clock controllers
   - AXS10X I2S PLL
   - Rockchip RK3399 clock and reset controller

  Updates:

   - MMC2 and UART2 clks on Samsung Exynos 3250, ACLK on Samsung Exynos
     542x SoCs, and some more clk ID exporting for bus frequency scaling
   - Proper BCM2835 PCM clk support and various other clks
   - i.MX clk updates for i.MX6SX, i.MX7, and VF610
   - Renesas updates for R-Car H3
   - Tegra210 got updates for DisplayPort and HDMI 2.0
   - Rockchip driver refactorings and fixes due to adding RK3399 support"
