Pull x86 fixes from Thomas Gleixner:
 "A few fixes for x86:

   - Fix a boot regression caused by the recent bootparam sanitizing
     change, which escaped the attention of all people who reviewed that
     code.

   - Address a boot problem on machines with broken E820 tables caused
     by an underflow which ended up placing the trampoline start at
     physical address 0.

   - Handle machines which do not advertise a legacy timer of any form,
     but need calibration of the local APIC timer gracefully by making
     the calibration routine independent from the tick interrupt. Marked
     for stable as well as there seems to be quite some new laptops
     rolled out which expose this.

   - Clear the RDRAND CPUID bit on AMD family 15h and 16h CPUs which are
     affected by broken firmware which does not initialize RDRAND
     correctly after resume. Add a command line parameter to override
     this for machine which either do not use suspend/resume or have a
     fixed BIOS. Unfortunately there is no way to detect this on boot,
     so the only safe decision is to turn it off by default.

   - Prevent RFLAGS from being clobbers in CALL_NOSPEC on 32bit which
     caused fast KVM instruction emulation to break.

   - Explain the Intel CPU model naming convention so that the repeating
     discussions come to an end"

c49a0a8013 x86/CPU/AMD: Clear RDRAND CPUID bit on AMD family 15h/16h
There have been reports of RDRAND issues after resuming from suspend on
some AMD family 15h and family 16h systems. This issue stems from a BIOS
not performing the proper steps during resume to ensure RDRAND continues
to function properly.

RDRAND support is indicated by CPUID Fn00000001_ECX[30]. This bit can be
reset by clearing MSR C001_1004[62]. Any software that checks for RDRAND
support using CPUID, including the kernel, will believe that RDRAND is
not supported.

Update the CPU initialization to clear the RDRAND CPUID bit for any family
15h and 16h processor that supports RDRAND. If it is known that the family
15h or family 16h system does not have an RDRAND resume issue or that the
system will not be placed in suspend, the "rdrand=force" kernel parameter
can be used to stop the clearing of the RDRAND CPUID bit.

Additionally, update the suspend and resume path to save and restore the
MSR C001_1004 value to ensure that the RDRAND CPUID setting remains in
place after resuming from suspend.

Note, that clearing the RDRAND CPUID bit does not prevent a processor
that normally supports the RDRAND instruction from executing it. So any
code that determined the support based on family and model won't #UD.

414776621d net/tls: prevent skb_orphan() from leaking TLS plain text with offload
sk_validate_xmit_skb() and drivers depend on the sk member of
struct sk_buff to identify segments requiring encryption.
Any operation which removes or does not preserve the original TLS
socket such as skb_orphan() or skb_clone() will cause clear text
leaks.

Make the TCP socket underlying an offloaded TLS connection
mark all skbs as decrypted, if TLS TX is in offload mode.
Then in sk_validate_xmit_skb() catch skbs which have no socket
(or a socket with no validation) and decrypted flag set.

Note that CONFIG_SOCK_VALIDATE_XMIT, CONFIG_TLS_DEVICE and
sk->sk_validate_xmit_skb are slightly interchangeable right now,
they all imply TLS offload. The new checks are guarded by
CONFIG_TLS_DEVICE because that's the option guarding the
sk_buff->decrypted member.

Second, smaller issue with orphaning is that it breaks
the guarantee that packets will be delivered to device
queues in-order. All TLS offload drivers depend on that
scheduling property. This means skb_orphan_partial()'s
trick of preserving partial socket references will cause
issues in the drivers. We need a full orphan, and as a
result netem delay/throttling will cause all TLS offload
skbs to be dropped.

Reusing the sk_buff->decrypted flag also protects from
leaking clear text when incoming, decrypted skb is redirected
(e.g. by TC).

See commit 0608c69c9a ("bpf: sk_msg, sock{map|hash} redirect
through ULP") for justification why the internal flag is safe.
The only location which could leak the flag in is tcp_bpf_sendmsg(),
which is taken care of by clearing the previously unused bit.

v2:
 - remove superfluous decrypted mark copy (Willem);
 - remove the stale doc entry (Boris);
 - rely entirely on EOR marking to prevent coalescing (Boris);
 - use an internal sendpages flag instead of marking the socket
   (Boris).
v3 (Willem):
 - reorganize the can_skb_orphan_partial() condition;
 - fix the flag leak-in through tcp_bpf_sendmsg.

Pull pti updates from Thomas Gleixner:
 "The performance deterioration departement is not proud at all to
  present yet another set of speculation fences to mitigate the next
  chapter in the 'what could possibly go wrong' story.

  The new vulnerability belongs to the Spectre class and affects GS
  based data accesses and has therefore been dubbed 'Grand Schemozzle'
  for secret communication purposes. It's officially listed as
  CVE-2019-1125.

  Conditional branches in the entry paths which contain a SWAPGS
  instruction (interrupts and exceptions) can be mis-speculated which
  results in speculative accesses with a wrong GS base.

  This can happen on entry from user mode through a mis-speculated
  branch which takes the entry from kernel mode path and therefore does
  not execute the SWAPGS instruction. The following speculative accesses
  are done with user GS base.

  On entry from kernel mode the mis-speculated branch executes the
  SWAPGS instruction in the entry from user mode path which has the same
  effect that the following GS based accesses are done with user GS
  base.

  If there is a disclosure gadget available in these code paths the
  mis-speculated data access can be leaked through the usual side
  channels.

  The entry from user mode issue affects all CPUs which have speculative
  execution. The entry from kernel mode issue affects only Intel CPUs
  which can speculate through SWAPGS. On CPUs from other vendors SWAPGS
  has semantics which prevent that.

  SMAP migitates both problems but only when the CPU is not affected by
  the Meltdown vulnerability.

  The mitigation is to issue LFENCE instructions in the entry from
  kernel mode path for all affected CPUs and on the affected Intel CPUs
  also in the entry from user mode path unless PTI is enabled because
  the CR3 write is serializing.

  The fences are as usual enabled conditionally and can be completely
  disabled on the kernel command line. The Spectre V1 documentation is
  updated accordingly.

  A big "Thank You!" goes to Josh for doing the heavy lifting for this
  round of hardware misfeature 'repair'. Of course also "Thank You!" to
  everybody else who contributed in one way or the other"

5d92e631b8 net/tls: partially revert fix transition through disconnect with close
Looks like we were slightly overzealous with the shutdown()
cleanup. Even though the sock->sk_state can reach CLOSED again,
socket->state will not got back to SS_UNCONNECTED once
connections is ESTABLISHED. Meaning we will see EISCONN if
we try to reconnect, and EINVAL if we try to listen.

Only listen sockets can be shutdown() and reused, but since
ESTABLISHED sockets can never be re-connected() or used for
listen() we don't need to try to clean up the ULP state early.

88c5083442 Wimplicit-fallthrough patches for 5.3-rc2
Hi Linus,
 
 Please, pull the following patches that mark switch cases where we are
 expecting to fall through. These patches are part of the ongoing efforts
 to enable -Wimplicit-fallthrough. Most of them have been baking in linux-next
 for a whole development cycle.
 
 Also, pull the Makefile patch that globally enables the
 -Wimplicit-fallthrough option.
 
 Finally, some missing-break fixes that have been tagged for -stable:
 
  - drm/amdkfd: Fix missing break in switch statement
  - drm/amdgpu/gfx10: Fix missing break in switch statement
 
 Notice that with these changes, we completely get rid of all the
 fall-through warnings in the kernel.
 
 Thanks

2bcbeaefde mm/hmm: always return EBUSY for invalid ranges in hmm_range_{fault,snapshot}
We should not have two different error codes for the same
condition. EAGAIN must be reserved for the FAULT_FLAG_ALLOW_RETRY retry
case and signals to the caller that the mmap_sem has been unlocked.

Use EBUSY for the !valid case so that callers can get the locking right.

as seen in the virt/ top-level directory.  Fix up the documentation
