      x86: fix error handling for 32-bit compat out-of-range system call numbers · cd88ec23
      Linus Torvalds authored
      Commit 3f5159a9 ("x86/asm/entry/32: Update -ENOSYS handling to match
      the 64-bit logic") broke the ENOSYS handling for the 32-bit compat case.
      The proper error return value was never loaded into %rax, except if
      things just happened to go through the audit paths, which ended up
      reloading the return value.
      
      This moves the loading or %rax into the normal system call path, just to
      make sure the error case triggers it.  It's kind of sad, since it adds a
      useless instruction to reload the register to the fast path, but it's
      not like that single load from the stack is going to be noticeable.

      Revert x86 sigcontext cleanups · ed596cde
      Linus Torvalds authored
      This reverts commits 9a036b93 ("x86/signal/64: Remove 'fs' and 'gs'
      from sigcontext") and c6f20629 ("x86/signal/64: Fix SS handling for
      signals delivered to 64-bit programs").
      
      They were cleanups, but they break dosemu by changing the signal return
      behavior (and removing 'fs' and 'gs' from the sigcontext struct - while
      not actually changing any behavior - causes build problems).

      HID: wacom: Report correct device resolution when using the wireless adapater · 0be01712
      Jason Gerecke authored
      The 'wacom_wireless_work' function does not recalculate the tablet's
      resolution, causing the value contained in the 'features' struct to
      always be reported to userspace. This value is valid only for the pen
      interface, meaning that the value will be incorrect for the touchpad (if
      present). This in particular causes problems for libinput which relies
      on the reported resolution being correct.
      
      This patch adds the necessary calls to recalculate the resolution for
      each interface. This requires a little bit of code shuffling since both
      the 'wacom_set_default_phy' and 'wacom_calculate_res' are declared below
      their new first point of use in 'wacom_wireless_work'.

      bnx2x: Free NVRAM lock at end of each page · 0ea853df
      Yuval Mintz authored
      Writing each 4Kb page into flash might take up-to ~100 miliseconds,
      during which time management firmware cannot acces the nvram for its
      own uses.
      
      Firmware upgrade utility use the ethtool API to burn new flash images
      for the device via the ethtool API, doing so by writing several page-worth
      of data on each command. Such action might create problems for the
      management firmware, as the nvram might not be accessible for a long time.
      
      This patch changes the write implementation, releasing the nvram lock on
      the completion of each page, allowing the management firmware time to
      claim it and perform its own required actions.
