Subject: [PATCH v2 0/2] Switching ARC to optimized generic strncpy_from_user
Date: Wed, 15 Jan 2020 16:21:22 -0800
Message-ID: <> (raw)


This series switches ARC to generic word-at-a-time interface.

I understand that going fwd, we may drop the inline versions altogether but this
helps ARC code in the interim.

v2 <- v1
 - Moved __strnlen_user/__strncpy_from_user to under ifdef gaurd [Arnd]
 - Dropped the broken optimization patch [Linus]
 - Folded 2 ARC patches into 1


Vineet Gupta (2):
  asm-generic/uaccess: don't define inline functions if noinline lib/*
    in use
  ARC: uaccess: use optimized generic __strnlen_user/__strncpy_from_user
