Subject: asm-generic headers: uaccess.h to conditionally define segment_eq()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=10a6007bda48e3524e24ce1ad46dc7be1add6a0e;p=linux-beck.git

asm-generic headers: uaccess.h to conditionally define segment_eq()

This is because mm_segment_t is exported by arch code, while seqment_eq
assumes it will have .seg element.
