x86/dumpstack: Make stack name tags more comprehensible
NMI stack dumps are bracketed by the following tags: <NMI> ... <EOE> The ending tag is kind of confusing if you don't already know what "EOE" means (end of exception). The same ending tag is also used to mark the end of all other exceptions' stacks. For example: <#DF> ... <EOE> And similarly, "EOI" is used as the ending tag for interrupts: <IRQ> ... <EOI> Change the tags to be more comprehensible by making them symmetrical and more XML-esque: <NMI> ... </NMI> <#DF> ... </#DF> <IRQ> ... </IRQ> Signed-off-by: Josh Poimboeuf <jpoimboe@redhat.com> Acked-by: Frederic Weisbecker <fweisbec@gmail.com> Acked-by: Peter Zijlstra (Intel) <peterz@infradead.org> Cc: Andy Lutomirski <luto@kernel.org> Cc: Borislav Petkov <bp@alien8.de> Cc: Brian Gerst <brgerst@gmail.com> Cc: Denys Vlasenko <dvlasenk@redhat.com> Cc: H.
