2a0ff3fbe3 cgroup: warn about mismatching options of a new mount of an existing hierarchy
With the new __DEVEL__sane_behavior mount option was introduced,
if the root cgroup is alive with no xattr function, to mount a
new cgroup with xattr will be rejected in terms of design which
just fine.  However, if the root cgroup does not mounted with
__DEVEL__sane_hehavior, to create a new cgroup with xattr option
will succeed although after that the EA function does not works
as expected but will get ENOTSUPP for setting up attributes under
either cgroup. e.g.

setfattr: /cgroup2/test: Operation not supported

Instead of keeping silence in this case, it's better to drop a log
entry in warning level.  That would be helpful to understand the
reason behind the scene from the user's perspective, and this is
essentially an improvement does not break the backward compatibilities.

With this fix, above mount attemption will keep up works as usual but
the following line cound be found at the system log:

[ ...] cgroup: new mount options do not match the existing superblock

tj: minor formatting / message updates.

e9d0626ed4 x86-64, init: Fix a possible wraparound bug in switchover in head_64.S
In head_64.S, a switchover has been used to handle kernel crossing
1G, 512G boundaries.

And commit 8170e6bed4
    x86, 64bit: Use a #PF handler to materialize early mappings on demand
said:
    During the switchover in head_64.S, before #PF handler is available,
    we use three pages to handle kernel crossing 1G, 512G boundaries with
    sharing page by playing games with page aliasing: the same page is
    mapped twice in the higher-level tables with appropriate wraparound.

But from the switchover code, when we set up the PUD table:
114         addq    $4096, %rdx
115         movq    %rdi, %rax
116         shrq    $PUD_SHIFT, %rax
117         andl    $(PTRS_PER_PUD-1), %eax
118         movq    %rdx, (4096+0)(%rbx,%rax,8)
119         movq    %rdx, (4096+8)(%rbx,%rax,8)

It seems line 119 has a potential bug there. For example,
if the kernel is loaded at physical address 511G+1008M, that is
    000000000 111111111 111111000 000000000000000000000
and the kernel _end is 512G+2M, that is
    000000001 000000000 000000001 000000000000000000000
So in this example, when using the 2nd page to setup PUD (line 114~119),
rax is 511.
In line 118, we put rdx which is the address of the PMD page (the 3rd page)
into entry 511 of the PUD table. But in line 119, the entry we calculate from
(4096+8)(%rbx,%rax,8) has exceeded the PUD page. IMO, the entry in line
119 should be wraparound into entry 0 of the PUD table.

The patch fixes the bug.

b161c14440 svcrpc: implement O_NONBLOCK behavior for use-gss-proxy
Somebody noticed LTP was complaining about O_NONBLOCK opens of
/proc/net/rpc/use-gss-proxy succeeding and then a following read
hanging.

I'm not convinced LTP really has any business opening random proc files
and expecting them to behave a certain way.  Maybe this isn't really a
bug.

But in any case the O_NONBLOCK behavior could be useful for someone that
wants to test whether gss-proxy is up without waiting.

e3bf756eb9 Two more fixes:
The first one was reported by Mauro Carvalho Chehab, where if a poll()
 is done against a trace buffer for a CPU that has never been online,
 it will crash the kernel, as buffers are only created when a CPU comes
 on line, but the trace files are for all possible CPUs.
 
 This fix is to check if the buffer was allocated and if not return -EINVAL.
 
 That was the simple fix, the real fix is a bit more complex and not for
 a -rc release. We could have the files created when the CPUs come online.
 That would require some design changes.
 
 The second one was reported by Peter Zijlstra. If the kernel command line
 has ftrace=nop, it will lock up the system on boot up. This is because
 the new design for 3.10 has the nop tracer bootstrap the tracing subsystem.
 When ftrace=<trace> is defined, when a that tracer is registered, it
 starts the tracing, but uses the nop tracer to clear things out.
 What happened here was that ftrace=nop caused the registering of nop
 to start it and use nop before it was initialized.
 
 The only thing nop needs to have done to initialize it is to have the
 tracer point its current_tracer structure member to the nop tracer.
 Doing that before registering the nop tracer makes everything work.

During recent refactoring the code to report removal when MICDET reports
an absent microphone was removed, causing problems for systems which rely
solely on the MICDET for this functionality. Restore it.

In the (not so useful) kernel configuration where CONFIG_SWAP
is undefined and CONFIG_XEN_SELFBALLOONING is defined,
xen_tmem_init would use undefined variable 'static bool frontswap'.

Added #else to have #define frontswap (0) in the case where
CONFIG_FRONTSWAP is not defined.

f96ef988cc ipv4: fix redirect handling for TCP packets
Unlike ipv4_redirect() and ipv4_sk_redirect(), ip_do_redirect()
doesn't call __build_flow_key() directly but via
ip_rt_build_flow_key() wrapper. This leads to __build_flow_key()
getting pointer to IPv4 header of the ICMP redirect packet
rather than pointer to the embedded IPv4 header of the packet
initiating the redirect.

As a result, handling of ICMP redirects initiated by TCP packets
is broken. Issue was introduced by

de614e561b crypto: sha256_ssse3 - fix stack corruption with SSSE3 and AVX implementations
The _XFER stack element size was set too small, 8 bytes, when it needs to be
16 bytes. As _XFER is the last stack element used by these implementations,
the 16 byte stores with 'movdqa' corrupt the stack where the value of register
%r12 is temporarily stored. As these implementations align the stack pointer
to 16 bytes, this corruption did not happen every time.

Patch corrects this issue.

The GPIO states need to be restored after s2r and this is not currently
supported in the pinctrl driver. This patch saves the gpio states before
suspend and restores them after resume.

Saving and restoring is done very early using syscore_ops and must
happen before pins are released from their powerdown state.
