This patch has a couple of checkpatch issues:

CHECK: Alignment should match open parenthesis
CHECK: Please don't use multiple blank lines
CHECK: Please use a blank line after function/struct/union/enum declarations
CHECK: Unnecessary parentheses around 'global->nr_guest_ids < IMSIC_MIN_ID'
CHECK: Unnecessary parentheses around 'global->nr_guest_ids >= IMSIC_MAX_ID'
CHECK: Unnecessary parentheses around 'global->nr_ids < IMSIC_MIN_ID'
CHECK: Unnecessary parentheses around 'global->nr_ids >= IMSIC_MAX_ID'
CHECK: Unnecessary parentheses around global->local
CHECK: Unnecessary parentheses around imsic->lpriv
CHECK: extern prototypes should be avoided in .h files
