Subject: Re: [PATCH v2 1/4] mm: declare VMA flags by bit

Hi Andrew,

Sorry to be a pain, seems build bots are sleeping on parisc32/64 as there was
some accidental duplication of VM_STACK_EARLY when CONFIG_STACK_GROWSUP is
specified (currently only a parisc thing :).

The attached fix-patch fixes this and some broken whitespace.

Many thanks to David H. who noticed this and pinged me off-list!

Cheers, Lorenzo
