        Most of them are for the new mlxbf driver which got more exposure
        after rc1. The sh_mobile patch should already have reached you during
        the merge window, but I accidently dropped it. However, since it fixes
        a problem with rebooting, it is still fine for rc3"

       "It's Friday here so that means another installment of drm fixes to
        distract you from the counting process.
      
        Changes all over the place, the amdgpu changes contain support for a
        new GPU that is close to current one already in the tree (Green
        Sardine) so it shouldn't have much side effects.
      
        Otherwise imx has a few cleanup patches and fixes, amdgpu and i915
        have around the usual smattering of fixes, fonts got constified, and
        vc4/panfrost has some minor fixes. All in all a fairly regular rc3.
      
        We have an outstanding nouveau regression, but the author is looking
        into the fix, so should be here next week.
      
        I now return you to counting.

      tpm: efi: Don't create binary_bios_measurements file for an empty log · 8ffd778a
      Tyler Hicks authored
      Mimic the pre-existing ACPI and Device Tree event log behavior by not
      creating the binary_bios_measurements file when the EFI TPM event log is
      empty.
      
      This fixes the following NULL pointer dereference that can occur when
      reading /sys/kernel/security/tpm0/binary_bios_measurements after the

      In this situation, the bios_event_log pointer in the tpm_bios_log struct
      was not NULL but was equal to the ZERO_SIZE_PTR (0x10) value. This was
      due to the following kmemdup() in tpm_read_log_efi():
      
      int tpm_read_log_efi(struct tpm_chip *chip)
      {
      ...
      	/* malloc EventLog space */
      	log->bios_event_log = kmemdup(log_tbl->log, log_size, GFP_KERNEL);
      	if (!log->bios_event_log) {
      		ret = -ENOMEM;
      		goto out;
      	}
      ...
      }
      
      When log_size is zero, due to an empty event log from firmware,
      ZERO_SIZE_PTR is returned from kmemdup(). Upon a read of the
      binary_bios_measurements file, the tpm2_bios_measurements_start()
      function does not perform a ZERO_OR_NULL_PTR() check on the
      bios_event_log pointer before dereferencing it.
      
      Rather than add a ZERO_OR_NULL_PTR() check in functions that make use of
      the bios_event_log pointer, simply avoid creating the
      binary_bios_measurements_file as is done in other event log retrieval
      backends.
      
      Explicitly ignore all of the events in the final event log when the main
      event log is empty. The list of events in the final event log cannot be
      accurately parsed without referring to the first event in the main event
      log (the event log header) so the final event log is useless in such a
      situation.
      
      Fixes: 58cc1e4f ("tpm: parse TPM event logs based on EFI table")

      tpm_tis: Disable interrupts on ThinkPad T490s · b154ce11
      Jerry Snitselaar authored
      There is a misconfiguration in the bios of the gpio pin used for the
      interrupt in the T490s. When interrupts are enabled in the tpm_tis
      driver code this results in an interrupt storm. This was initially
      reported when we attempted to enable the interrupt code in the tpm_tis
      driver, which previously wasn't setting a flag to enable it. Due to
      the reports of the interrupt storm that code was reverted and we went back
      to polling instead of using interrupts. Now that we know the T490s problem
      is a firmware issue, add code to check if the system is a T490s and
      disable interrupts if that is the case. This will allow us to enable
      interrupts for everyone else. If the user has a fixed bios they can
      force the enabling of interrupts with tpm_tis.interrupts=1 on the
      kernel command line.

      i2c: designware: slave should do WRITE_REQUESTED before WRITE_RECEIVED · 3b5f7f10
      Michael Wu authored
      Sometimes we would get the following flow when doing an i2cset:
      
      0x1 STATUS SLAVE_ACTIVITY=0x1 : RAW_INTR_STAT=0x514 : INTR_STAT=0x4
      I2C_SLAVE_WRITE_RECEIVED
      0x1 STATUS SLAVE_ACTIVITY=0x0 : RAW_INTR_STAT=0x714 : INTR_STAT=0x204
      I2C_SLAVE_WRITE_REQUESTED
      I2C_SLAVE_WRITE_RECEIVED
      
      Documentation/i2c/slave-interface.rst says that I2C_SLAVE_WRITE_REQUESTED,
      which is mandatory, should be sent while the data did not arrive yet. It
      means in a write-request I2C_SLAVE_WRITE_REQUESTED should be reported
      before any I2C_SLAVE_WRITE_RECEIVED.
      
      By the way, I2C_SLAVE_STOP didn't be reported in the above case because
      DW_IC_INTR_STAT was not 0x200.
      
      dev->status can be used to record the current state, especially Designware
      I2C controller has no interrupts to identify a write-request. This patch
      makes not only I2C_SLAVE_WRITE_REQUESTED been reported first when
      IC_INTR_RX_FULL is rising and dev->status isn't STATUS_WRITE_IN_PROGRESS
      but also I2C_SLAVE_STOP been reported when a STOP condition is received.

      i2c: designware: call i2c_dw_read_clear_intrbits_slave() once · 66b92313
      Michael Wu authored
      If some bits were cleared by i2c_dw_read_clear_intrbits_slave() in
      i2c_dw_isr_slave() and not handled immediately, those cleared bits would
      not be shown again by later i2c_dw_read_clear_intrbits_slave(). They
      therefore were forgotten to be handled.
      
      i2c_dw_read_clear_intrbits_slave() should be called once in an ISR and take
      its returned state for all later handlings.

      RISC-V: Fix the VDSO symbol generaton for binutils-2.35+ · c2c81bb2
      Palmer Dabbelt authored
      We were relying on GNU ld's ability to re-link executable files in order
      to extract our VDSO symbols.  This behavior was deemed a bug as of
      binutils-2.35 (specifically the binutils-gdb commit a87e1817a4 ("Have
      the linker fail if any attempt to link in an executable is made."), but
      as that has been backported to at least Debian's binutils-2.34 in may
      manifest in other places.
      
      The previous version of this was a bit of a mess: we were linking a
      static executable version of the VDSO, containing only a subset of the
      input symbols, which we then linked into the kernel.  This worked, but
      certainly wasn't a supported path through the toolchain.  Instead this
      new version parses the textual output of nm to produce a symbol table.
      Both rely on near-zero addresses being linkable, but as we rely on weak
      undefined symbols being linkable elsewhere I don't view this as a major
      issue.

      RISC-V: Use non-PGD mappings for early DTB access · 1074dd44
      Anup Patel authored
      Currently, we use PGD mappings for early DTB mapping in early_pgd
      but this breaks Linux kernel on SiFive Unleashed because on SiFive
      Unleashed PMP checks don't work correctly for PGD mappings.
      
      To fix early DTB mappings on SiFive Unleashed, we use non-PGD
      mappings (i.e. PMD) for early DTB access.

      riscv: Set text_offset correctly for M-Mode · 79605f13
      Sean Anderson authored
      M-Mode Linux is loaded at the start of RAM, not 2MB later. Perhaps this
      should be calculated based on PAGE_OFFSET somehow? Even better would be to
      deprecate text_offset and instead introduce something absolute.
