Xiaoting Liu 6f4a46f0eb hwmon: (pmbus) associate PMBUS_SKIP_STATUS_CHECK with driver data
Current code compares device name with name in i2c_device_id to decide
whether PMBUS_SKIP_STATUS_CHECK should be set in pmbus_platform_data,
which makes adding new devices with PMBUS_SKIP_STATUS_CHECK should also
modify code in pmbus_probe().

This patch adds pmbus_device_info to save pages and flags. Its pointer
is put in driver_data of i2c_device_id, which makes adding new device
more straightforward.

Fix tps53679_probe() by using dynamically allocated "pmbus_driver_info"
structure instead of static. Usage of static structures causes
overwritten of the field "vrm_version", in case the system is equipped
with several tps53679 devices with the different "vrm_version".
In such case the last probed device overwrites this field for all
others.

Now that LEDs core allows "blocking" flavor of "set brightness" method we
can use it and get rid of private work item. As a bonus, we are no longer
forgetting to cancel it when we unbind the driver.

Michael Ellerman a58007621b powerpc/64s: Fix possible corruption on big endian due to pgd/pud_present()
In v4.20 we changed our pgd/pud_present() to check for _PAGE_PRESENT
rather than just checking that the value is non-zero, e.g.:

  static inline int pgd_present(pgd_t pgd)
  {
 -       return !pgd_none(pgd);
 +       return (pgd_raw(pgd) & cpu_to_be64(_PAGE_PRESENT));
  }

Unfortunately this is broken on big endian, as the result of the
bitwise & is truncated to int, which is always zero because
_PAGE_PRESENT is 0x8000000000000000ul. This means pgd_present() and
pud_present() are always false at compile time, and the compiler
elides the subsequent code.

Remarkably with that bug present we are still able to boot and run
with few noticeable effects. However under some work loads we are able
to trigger a warning in the ext4 code:

  WARNING: CPU: 11 PID: 29593 at fs/ext4/inode.c:3927 .ext4_set_page_dirty+0x70/0xb0
  CPU: 11 PID: 29593 Comm: debugedit Not tainted 4.20.0-rc1 #1
  ...
  NIP .ext4_set_page_dirty+0x70/0xb0
  LR  .set_page_dirty+0xa0/0x150
  Call Trace:
   .set_page_dirty+0xa0/0x150
   .unmap_page_range+0xbf0/0xe10
   .unmap_vmas+0x84/0x130

   .__vm_munmap+0x80/0x110
   .__se_sys_munmap+0x14/0x30
   system_call+0x5c/0x70

The fix is simple, we need to convert the result of the bitwise & to
an int before returning it.

Thanks to Erhard, Jan Kara and Aneesh for help with debugging.
