IB/ipath: Use unsigned long for irq flags
A few functions in the ipath driver incorrectly use unsigned int to hold irq flags for spin_lock_irqsave(). This patch was generated using the Coccinelle framework with the following semantic patch: The semantic patch I used was this: @@ expression lock; identifier flags; expression subclass; @@ - unsigned int flags; + unsigned long flags; ... <+... ( spin_lock_irqsave(lock, flags) | _spin_lock_irqsave(lock) | spin_unlock_irqrestore(lock, flags) | _spin_unlock_irqrestore(lock, flags) | read_lock_irqsave(lock, flags) | _read_lock_irqsave(lock) | read_unlock_irqrestore(lock, flags) | _read_unlock_irqrestore(lock, flags) | write_lock_irqsave(lock, flags) | _write_lock_irqsave(lock) | write_unlock_irqrestore(lock, flags) | _write_unlock_irqrestore(lock, flags) | spin_lock_irqsave_nested(lock, flags, subclass) | _spin_lock_irqsave_nested(lock, subclass) | spin_unlock_irqrestore(lock, flags) | _spin_unlock_irqrestore(lock, flags) | _raw_spin_lock_flags(lock, flags) | __raw_spin_lock_flags(lock, flags) ) ...+> Cc: Ralph Campbell <ralph.campbell@qlogic.com> Cc: Julia Lawall <julia@diku.dk> Cc: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: Vegard Nossum <vegard.nossum@gmail.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
