ARM: kernel: avoid brute force search on PLT generation
(2016-08-30 17:45:34 +0100)
----------------------------------------------------------------
This series of 4 patches optimizes the ARM PLT generation code that
is invoked at module load time, to get rid of the O(n^2) algorithm
that results in pathological load times of 10 seconds or more for
large modules on certain STB platforms
----------------------------------------------------------------
Ard Biesheuvel (4):
ARM: kernel: merge core and init PLTs
ARM: kernel: allocate PLT entries only for external symbols
ARM: kernel: sort relocation sections before allocating PLTs
ARM: kernel: avoid brute force search on PLT generation
