Description William Cohen 2007-05-23 22:23:53 UTC 
The /systemtap.stress/conversions.exp test fails on ia64. the tests works for
0xffffffff. Below is the related part of the systemtap.log:

exp conversions.stp 0xffffffffffffffff 0
ERROR: kernel long copy fault at 0xffffffffffffffff near identifier

done conversions.stp 0xffffffffffffffff 6

The test above seems to be missing the failures for:

ERROR: kernel string copy fault
ERROR: kernel char copy fault

Page 149 of the "ia64 linux kernel", figure 4.11 shows that address mapping,
0xffffffffffffffff is a valid byte address. Might need to reconsider how this
tests picks the addresses.
Comment 1 Frank Ch. Eigler 2007-05-28 14:19:42 UTC 
We already have customizations of that test for s390x.
Think of something similar for ia64.
Comment 2 William Cohen 2007-05-29 20:53:17 UTC 
Put in test for ia64 in conversion.exp to use an address that is falls in region
5 if on ia64 machine.
Comment 3 Josh Stone 2007-08-13 22:42:23 UTC 
Will put in the ia64 check, and it's been passing in weekly tests since then...
Comment 4 Bruno Abinader 2008-03-03 18:12:35 UTC 
Test testsuite/.../conversions.exp currently fails on arm target with this output:

FAIL: conversions.stp 0xffffffff (6)
FAIL: conversions.stp 0xffffffffffffffff (6)

This test depends on architecture-specific memory addressing conventions. There
is no special treatment for ARM in this case.

ps: This bug is the same as bug #4121.
Comment 5 Frank Ch. Eigler 2008-03-03 18:25:19 UTC 
Let's use a new ARM-specific bug for this.
Please suggest a known-invalid address range if you can.
