Subject: [PATCH v2 0/3] xen/x86: Improvements to asm assertions
Date: Tue, 14 Apr 2015 11:51:37 +0100 [thread overview]
Message-ID: <1429008700-10718-1-git-send-email-andrew.cooper3@citrix.com> (raw)
In XenServer, we have a single server which occasionally finds interrupts
unexpectedtly in the wrong state (I suspect the SMM handler). However,
asserts from ASSERT_INTERRUPTS_{EN,DIS}ABLED are quite opaque, being an
unqualified fatal #UD.
Changes in v2:
* Use mergable string sections
* Use \@ rather than raw numbers
* Style fixes
