Karicheri, Muralidharan 9ecfe875c4 net: ti: netcp: restore get/set_pad_info() functionality ... The commit 8990777914 ("netcp: try to reduce type confusion in descriptors") introduces a regression in Kernel 4.5-rc1 and it breaks get/set_pad_info() functionality. The TI NETCP driver uses pad0 and pad1 fields of knav_dma_desc to store DMA/MEM buffer pointer and buffer size respectively. And in both cases for Keystone 2 the pointer type size is 32 bit regardless of LAPE enabled or not, because CONFIG_ARCH_DMA_ADDR_T_64BIT originally is not expected to be defined. Unfortunately, above commit changed buffer's pointers save/restore code (get/set_pad_info()) and added intermediate conversation to u64 which works incorrectly on 32bit Keystone 2 and causes TI NETCP driver crash in RX/TX path due to "Unable to handle kernel NULL pointer" exception. This issue was reported and discussed in [1]. Hence, fix it by partially reverting above commit and restoring get/set_pad_info() functionality as it was before.
