Subject: [MIPS] Fix struct sigcontext for N32 userland
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=269dd2b2526d046d8b43554ff27b486e2ddb3f08;p=linux-beck.git

[MIPS] Fix struct sigcontext for N32 userland

The kernel use 64-bit for sc_regs[0], and both N32/N64 userland
expects it was 64-bit.  But size of 'long' on N32 is actually 32-bit.
So this definition make some confusion.  Use __u32 and __u64 for
N32/N64 sigcontext to get rid of this confusion.
