This patch set changes a number of places where the kernel headers are
exported to user space and currently use explicit "long" or "unsigned
long" to use __kernel_[u]long_t in order to be compatible with the x32
user space ABI. These location are places where x32 uses the x86-64
ABI.
Has anybody checked how this affects MIPS n32 userspace?
I think it totally breaks it.
In addition, 109a1f32 (sysinfo: Use explicit types in <linux/sysinfo.h>)
is probably bad. I think it may need to be reverted, or somebody should
fix all the __kernel_{,u}long_t definitions for the ABI that may have
been broken by the change.
It is quite possible that some, or even all, of these locations should
really use dedicated types, but in the meantime this gives the correct
results which the current headers do not.
