      ACPI: x86: Add ACPI_QUIRK_UART1_SKIP for Lenovo Yoga Book yb1-x90f/l · f91280f3
      Hans de Goede authored 
      The Lenovo Yoga Book yb1-x90f/l 2-in-1 which ships with Android as
Factory OS has (another) bug in its DSDT where the UART resource for
the BTH0 ACPI device contains "\\_SB.PCIO.URT1" as path to the UART.

Note that is with a letter 'O' instead of the number '0' which is wrong.

This causes Linux to instantiate a standard /dev/ttyS? device for
the UART instead of a /sys/bus/serial device, which in turn causes
bluetooth to not work.

Similar DSDT bugs have been encountered before and to work around those
the acpi_quirk_skip_serdev_enumeration() helper exists.

Previous devices had the broken resource pointing to the first UART, while
the BT HCI was on the second UART, which ACPI_QUIRK_UART1_TTY_UART2_SKIP
deals with. Add a new ACPI_QUIRK_UART1_SKIP quirk for skipping enumeration
of UART1 instead for the Yoga Book case and add this quirk to the
existing DMI quirk table entry for the yb1-x90f/l .

This leaves the UART1 controller unbound allowing the x86-android-tablets
module to manually instantiate a serdev for it fixing bluetooth.

      ACPI: button: Add lid disable DMI quirk for Nextbook Ares 8A · 4fd55566
      Hans de Goede authored 
      The LID0 device on the Nextbook Ares 8A tablet always reports lid
closed causing userspace to suspend the device as soon as booting
is complete.

Add a DMI quirk to disable the broken lid functionality.

      ACPI: x86: Add skip i2c clients quirk for Nextbook Ares 8A · 69d6b376
      Hans de Goede authored 
      The Nextbook Ares 8A is a x86 ACPI tablet which ships with Android x86
as factory OS. Its DSDT contains a bunch of I2C devices which are not
actually there (the Android x86 kernel fork ignores I2C devices described
in the DSDT).

On this specific model this just not cause resource conflicts, one of
the probe() calls for the non existing i2c_clients actually ends up
toggling a GPIO or executing a _PS3 after a failed probe which turns
the tablet off.

Add a ACPI_QUIRK_SKIP_I2C_CLIENTS for the Nextbook Ares 8 to the
acpi_quirk_skip_dmi_ids table to avoid the bogus i2c_clients and
to fix the tablet turning off during boot because of this.

Also add the "10EC5651" HID for the RealTek ALC5651 codec used
in this tablet to the list of HIDs for which not to skipi2c_client
instantiation, since the Intel SST sound driver relies on
the codec being instantiated through ACPI.

      x86/retbleed: Fix return thunk alignment · 9a48d604
      Borislav Petkov (AMD) authored 
      SYM_FUNC_START_LOCAL_NOALIGN() adds an endbr leading to this layout
(leaving only the last 2 bytes of the address):

  3bff <zen_untrain_ret>:
  3bff:       f3 0f 1e fa             endbr64
  3c03:       f6                      test   $0xcc,%bl

  3c04 <__x86_return_thunk>:
  3c04:       c3                      ret
  3c05:       cc                      int3
  3c06:       0f ae e8                lfence

However, "the RET at __x86_return_thunk must be on a 64 byte boundary,
for alignment within the BTB."

Use SYM_START instead.

   free-space-tree instead of temporarily disabling it that would lead
   to a forced read-only mount

 - fix alignment check for offset when printing extent item
