83e3966411 ARM: SoC fixes for 5.17
This is a fairly large set of bugfixes, most of which had
 been sent a while ago but only now made it into the soc tree:
 
 Maintainer file updates:
 
  - Claudiu Beznea now co-maintains the at91 soc family,
    replacing Ludovic Desroches.
 
  - Michael Walle maintains the sl28cpld drivers
 
  - Alain Volmat and Raphael Gallais-Pou take over some
    drivers for ST platforms
 
  - Alim Akhtar is an additional reviewer for Samsung platforms
 
 Code fixes:
 
  - Op-tee had a problem with object lifetime that needs
    a slightly complex fix, as well as another bug with
    error handling.
 
  - Several minor issues for the OMAP platform, including
    a regression with the timer
 
  - A Kconfig change to fix a build-time issue on Intel
    SoCFPGA
 
 Device tree fixes:
 
  - The Amlogic Meson platform fixes a boot regression on
    am1-odroid, a spurious interrupt, and a problem with
    reserved memory regions
 
  - In the i.MX platform, several bug fixes are needed to
    make devices work correctly: SD card detection,
    alarmtimer, and sound card on some board. One patch
    for the GPU got in there by accident and gets reverted
    again.
 
  - TI K3 needs a fix for J721S2 serial port numbers
 
  - ux500 needs a fix to mount the SD card as root on
    the Skomer phone.

Actual SGX systems have 128GB of enclave memory or more.  The
"unclobbered_vdso_oversubscribed" selftest creates one enclave which
consumes all of the enclave memory on the system. Tearing down such a
large enclave takes around a minute, most of it in the loop where
the EREMOVE instruction is applied to each individual 4k enclave page.

Spending one minute in a loop triggers the softlockup detector.

Add a cond_resched() to give other tasks a chance to run and placate
the softlockup detector.

riscv: fix build with binutils 2.38
From version 2.38, binutils default to ISA spec version 20191213. This
means that the csr read/write (csrr*/csrw*) instructions and fence.i
instruction has separated from the `I` extension, become two standalone
extensions: Zicsr and Zifencei. As the kernel uses those instruction,
this causes the following build failure:

  CC      arch/riscv/kernel/vdso/vgettimeofday.o
  <<BUILDDIR>>/arch/riscv/include/asm/vdso/gettimeofday.h: Assembler messages:
  <<BUILDDIR>>/arch/riscv/include/asm/vdso/gettimeofday.h:71: Error: unrecognized opcode `csrr a5,0xc01'
  <<BUILDDIR>>/arch/riscv/include/asm/vdso/gettimeofday.h:71: Error: unrecognized opcode `csrr a5,0xc01'

  <<BUILDDIR>>/arch/riscv/include/asm/vdso/gettimeofday.h:71: Error: unrecognized opcode `csrr a5,0xc01'

The fix is to specify those extensions explicitely in -march. However as
older binutils version do not support this, we first need to detect
that.

the Lenovo IdeaPad 3 15IIL05 and the Lenovo IdeaPad 5 14IIL05, as well as
fixing thunderbolt hotplug issues on the Lenovo Yoga C940.

Unfortunately it turns out that this is causing issues with suspend/resume

policy, rever this. Note I'm looking into another fix for the issues this
fixed.

Since "MIPS: DTS: CI20: Add DT nodes for HDMI setup" has already

riscv: extable: fix err reg writing in dedicated uaccess handler
Mayuresh reported commit 20802d8d47 ("riscv: extable: add a dedicated
uaccess handler") breaks the writev02 test case in LTP. This is due to
the err reg isn't correctly set with the errno(-EFAULT in writev02
case). First of all, the err and zero regs are reg numbers rather than
reg offsets in struct pt_regs; Secondly, regs_set_gpr() should write
the regs when offset isn't zero(zero means epc)

Fix it by correcting regs_set_gpr() logic and passing the correct reg
offset to it.

ARM: dts: spear320: Drop unused and undocumented 'irq-over-gpio' property
The property 'irq-over-gpio' is both unused and undocumented. It also
happens to collide with standard *-gpio properties. As it is not needed,
drop it.

486343d372 Fixes for omaps
A series of fixes for omap variants for minor issues, and a fix for a timer
 regression for some omap3 beagleboard versions.
 
 The timer fix needs to patch both the dts and the timer code because
 otherwise the timer quirk handling for old dtbs will prevent the dts fix
 from working.
 
 The other changes are for issues found by automated analysis, a macasp
 typo fix, and two cosmetic fixes for clocks.

3037b174b1 ARM: socfpga: fix missing RESET_CONTROLLER
The SocFPGA machine since commit b3ca9888f3 ("reset: socfpga: add an
early reset driver for SoCFPGA") uses reset controller, so it should
select RESET_CONTROLLER explicitly.  Selecting ARCH_HAS_RESET_CONTROLLER
is not enough because it affects only default choice still allowing a
non-buildable configuration:

  /usr/bin/arm-linux-gnueabi-ld: arch/arm/mach-socfpga/socfpga.o: in function `socfpga_init_irq':

- Intel/PT: filters could crash the kernel
 
  - Intel: default disable the PMU for SMM, some new-ish EFI firmware has
    started using CPL3 and the PMU CPL filters don't discriminate against
    SMM, meaning that CPL3 (userspace only) events now also count EFI/SMM

   - More cleanups to the boot initialization sequence, from Dominik.

   - A fix for an old shortcoming with the ZAP ioctl, from me.

   - A workaround for a still unfixed Clang CFI/FullLTO compiler bug,
     from me. On one hand, it's a bummer to commit workarounds for
     experimental compiler features that have bugs. But on the other, I
     think this actually improves the code somewhat, independent of the

riscv: Fix XIP_FIXUP_FLASH_OFFSET
There were several problems with the calculation. Not only was an 'and'
being computed into t1 but thrown away; but the 'and' itself would
cause problems if the granularity of the XIP physical address was less
than XIP_OFFSET - in my case I had the kernel image at 2MB in SPI flash.

d2a02e3c8b lib/crypto: blake2s: avoid indirect calls to compression function for Clang CFI
blake2s_compress_generic is weakly aliased by blake2s_compress. The
current harness for function selection uses a function pointer, which is
ordinarily inlined and resolved at compile time. But when Clang's CFI is
enabled, CFI still triggers when making an indirect call via a weak
symbol. This seems like a bug in Clang's CFI, as though it's bucketing
weak symbols and strong symbols differently. It also only seems to
trigger when "full LTO" mode is used, rather than "thin LTO".

Nonetheless, the function pointer method isn't so terrific anyway, so
this patch replaces it with a simple boolean, which also gets inlined
away. This successfully works around the Clang bug.

In general, I'm not too keen on all of the indirection involved here; it
clearly does more harm than good. Hopefully the whole thing can get
cleaned up down the road when lib/crypto is overhauled more
comprehensively. But for now, we go with a simple bandaid.

riscv: eliminate unreliable __builtin_frame_address(1)
I tried different pieces of code which uses __builtin_frame_address(1)
(with both gcc version 7.5.0 and 10.3.0) to verify whether it works as
expected on riscv64. The result is negative.

What the compiler had generated is as below:
31                      fp = (unsigned long)__builtin_frame_address(1);
   0xffffffff80006024 <+200>:   ld      s1,0(s0)

It takes '0(s0)' as the address of frame 1 (caller), but the actual address
should be '-16(s0)'.

          |       ...       | <-+
          +-----------------+   |
          | return address  |   |
          | previous fp     |   |
          | saved registers |   |
          | local variables |   |
  $fp --> |       ...       |   |
          +-----------------+   |
          | return address  |   |
          | previous fp --------+
          | saved registers |
  $sp --> | local variables |
          +-----------------+

This leads the kernel can not dump the full stack trace on riscv.

[    7.222126][    T1] Call Trace:
[    7.222804][    T1] [<ffffffff80006058>] dump_backtrace+0x2c/0x3a

This problem is not exposed on most riscv builds just because the '0(s0)'
occasionally is the address frame 2 (caller's caller), if only ra and fp
are stored in frame 1 (caller).

          |       ...       | <-+
          +-----------------+   |
          | return address  |   |
  $fp --> | previous fp     |   |
          +-----------------+   |
          | return address  |   |
          | previous fp --------+
          | saved registers |
  $sp --> | local variables |
          +-----------------+

This could be a *bug* of gcc that should be fixed. But as noted in gcc
manual "Calling this function with a nonzero argument can have
unpredictable effects, including crashing the calling program.", let's
remove the '__builtin_frame_address(1)' in backtrace code.

With this fix now it can show full stack trace:
