Remove references to private kernel header and defines from exported
ib_user_verb.h file.
The code snippet below is used to reproduce the issue:
#include <stdio.h>
#include <rdma/ib_user_verb.h>
int main(void)
{
printf("IB_USER_VERBS_ABI_VERSION = %d\n", IB_USER_VERBS_ABI_VERSION);
return 0;
}
It fails during compilation phase with an error:
➜ /tmp gcc main.c
main.c:2:31: fatal error: rdma/ib_user_verb.h: No such file or directory
#include <rdma/ib_user_verb.h>
^
compilation terminated.

Description
-----------
The Standard Microsystems Corporation (SMSC) / Microchip EMC14xx chips
contain up to four temperature sensors. EMC14x2 support two sensors
(one internal, one external). EMC14x3 support three sensors (one internal,
two external), and EMC14x4 support four sensors (one internal, three
external).
The chips implement three limits for each sensor: low (tempX_min), high
(tempX_max) and critical (tempX_crit.) The chips also implement an
hysteresis mechanism which applies to all limits. The relative difference
is stored in a single register on the chip, which means that the relative
difference between the limit and its hysteresis is always the same for
all three limits.
This implementation detail implies the following:
* When setting a limit, its hysteresis will automatically follow, the
difference staying unchanged. For example, if the old critical limit
was 80 degrees C, and the hysteresis was 75 degrees C, and you change
the critical limit to 90 degrees C, then the hysteresis will
automatically change to 85 degrees C.
* The hysteresis values can't be set independently. We decided to make
only temp1_crit_hyst writable, while all other hysteresis attributes
are read-only. Setting temp1_crit_hyst writes the difference between
temp1_crit_hyst and temp1_crit into the chip, and the same relative
hysteresis applies automatically to all other limits.
* The limits should be set before the hysteresis.
