Subject: [S390] move (io|sysc)_restore_trace_psw into .data section
X-Git-Tag: v2.6.32-rc1~734^2~25
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a8c3cb4955d1a051732ead9ecf8bcffc8e7c039d;p=pandora-kernel.git

[S390] move (io|sysc)_restore_trace_psw into .data section

The sysc_restore_trace_psw and io_restore_trace_psw storage locations
are created in the .text section. When creating and IPLing from a named
saved system (NSS), writing to these locations causes a protection exception
(because the .text section is mapped as shared read-only in the NSS).

To permit write access, move the storage locations into the .data section.

The problem occurs only when CONFIG_TRACE_IRQFLAGS is set.
The git commmit that has introduced these variables is:
411788ea7fca01ee803af8225ac35807b4d02050
