Pull x86 cache flush updates from Thomas Gleixner:
"A reworked version of the opt-in L1D flush mechanism.
This is a stop gap for potential future speculation related hardware
vulnerabilities and a mechanism for truly security paranoid
applications.
It allows a task to request that the L1D cache is flushed when the
kernel switches to a different mm. This can be requested via prctl().
Changes vs the previous versions:
- Get rid of the software flush fallback
- Make the handling consistent with other mitigations
- Kill the task when it ends up on a SMT enabled core which defeats
the purpose of L1D flushing obviously"

After the recent ixp4xx cleanups, the ptp driver has gained a
build failure in some configurations:
drivers/net/ethernet/xscale/ptp_ixp46x.c: In function 'ptp_ixp_init':
drivers/net/ethernet/xscale/ptp_ixp46x.c:290:51: error: 'IXP4XX_TIMESYNC_BASE_VIRT' undeclared (first use in this function)
Avoid the last bit of hardcoded constants from platform headers
by turning the ptp driver bit into a platform driver and passing
the IRQ and MMIO address as resources.
This is a bit tricky:
- The interface between the two drivers is now the new
ixp46x_ptp_find() function, replacing the global
ixp46x_phc_index variable. The call is done as late
as possible, in hwtstamp_set(), to ensure that the
ptp device is fully probed.
- As the ptp driver is now called by the network driver, the
link dependency is reversed, which in turn requires a small
Makefile hack
- The GPIO number is still left hardcoded. This is clearly not
great, but it can be addressed later. Note that commit 98ac0cc270b7
("ARM: ixp4xx: Convert to MULTI_IRQ_HANDLER") changed the
IRQ number to something meaningless. Passing the correct IRQ
in a resource fixes this.
- When the PTP driver is disabled, ethtool .get_ts_info()
now correctly lists only software timestamping regardless
of the hardware.

Like the implementation of AESNI/AVX, this patch adds an accelerated
implementation of AESNI/AVX2. In terms of code implementation, by
reusing AESNI/AVX mode-related codes, the amount of code is greatly
reduced. From the benchmark data, it can be seen that when the block
size is 1024, compared to AVX acceleration, the performance achieved
by AVX2 has increased by about 70%, it is also 7.7 times of the pure
software implementation of sm4-generic.
The main algorithm implementation comes from SM4 AES-NI work by
libgcrypt and Markku-Juhani O. Saarinen at:
https://github.com/mjosaarinen/sm4ni
This optimization supports the four modes of SM4, ECB, CBC, CFB,
and CTR. Since CBC and CFB do not support multiple block parallel
encryption, the optimization effect is not obvious.
Benchmark on Intel i5-6200U 2.30GHz, performance data of three
implementation methods, pure software sm4-generic, aesni/avx
acceleration, and aesni/avx2 acceleration, the data comes from
the 218 mode and 518 mode of tcrypt. The abscissas are blocks of
different lengths. The data is tabulated and the unit is Mb/s:

Pull arm64 fix from Will Deacon:
"We received a report this week that the generic version of
pfn_valid(), which we switched to this merge window in 16c9afc77660
("arm64/mm: drop HAVE_ARCH_PFN_VALID"), interacts badly with
dma_map_resource() due to the following check:
/* Don't allow RAM to be mapped */
if (WARN_ON_ONCE(pfn_valid(PHYS_PFN(phys_addr))))
return DMA_MAPPING_ERROR;
Since the ongoing saga to determine the semantics of pfn_valid() is
unlikely to be resolved this week (does it indicate valid memory, or
just the presence of a struct page, or whether that struct page has
been initialised?), just revert back to our old version of pfn_valid()
for 5.14.

The secondary CPU start C routine uses nodat_stack as a
interim stack before finally switching to kernel_stack.
Such scheme is superfluous, since the assembler restart
interrupt handler (that secondary CPU starter is called
from) does not need to use any stack for switching into
DAT mode. Once DAT is on, any stack including virtually-
mapped one could be used.
Avoid the use of nodat_stack and smp_start_secondary()
helper. Instead, initiate kernel_stack directly from
the restart interrupt handler.

The restart interrupt is triggered whenever a secondary CPU is
brought online, a remote function call dispatched from another
CPU or a manual PSW restart is initiated and causes the system
to kdump. The handling routine is always called with DAT turned
off. It then initializes the stack frame and invokes a callback.
The existing callbacks handle DAT as follows:
* __do_restart() and __machine_kexec() turn in on upon entry;
* __ipl_run(), __reipl_run() and __dump_run() do not turn it
right away, but all of them call diag308() - which turns DAT
on, but only if kasan is enabled;
In addition to the described complexity all callbacks (and the
functions they call) should avoid kasan instrumentation while
DAT is off.
This update enables DAT in the assembler restart handler and
relieves any callbacks (which are mostly C functions) from
dealing with DAT altogether.
There are four types of CPU restart that initialize control
registers in different ways:
1. Start of secondary CPU on boot - control registers are
inherited from the IPL CPU;
2. Restart of online CPU - control registers of the CPU being
restarted are kept;
3. Hotplug of offline CPU - control registers are inherited
from the starting CPU;
4. Start of offline CPU triggered by manual PSW restart -
the control registers are read from the absolute lowcore
and contain the boot time IPL CPU values updated with all
follow-up calls of smp_ctl_set_bit() and smp_ctl_clear_bit()
routines;
In first three cases contents of the control registers is the
most recent. In the latter case control registers are good
enough to facilitate successful completion of kdump operation.

The u32 variable pci_dword is being masked with 0x1fffffff and then left
shifted 23 places. The shift is a u32 operation,so a value of 0x200 or
more in pci_dword will overflow the u32 and only the bottow 32 bits
are assigned to addr. I don't believe this was the original intent.
Fix this by casting pci_dword to a resource_size_t to ensure no
overflow occurs.
Note that the mask and 12 bit left shift operation does not need this
because the mask SNR_IMC_MMIO_MEM0_MASK and shift is always a 32 bit
value.
