Subject: [PATCH] kexec/ppc64: disabling exception handling when building the
|
|
|
de80c6 |
purgatory
|
|
|
de80c6 |
|
|
|
de80c6 |
Some Linux distributions would like to turn on the GCC exception handling
|
|
|
de80c6 |
by default. As this option introduces symbols in the built code that are
|
|
|
de80c6 |
defined in a separate shared library, this is not a good idea to have such
|
|
|
de80c6 |
an option activated when building the purgatory.
|
|
|
de80c6 |
|
|
|
de80c6 |
This patch forces the exception handling to be turned off when building the
|
|
|
de80c6 |
purgatory on ppc64 BE and LE.
