[patch 0/1] fix zero page reference in ob_pci_close

[Igor Kovalenko]

Hi!

I tried unmapping zero virtual address page for sparc64 and found there is an issue with ob_pci_close; it calls close-deblocker method without deblocker being open. This leads to multiple references to wrong cells, including ones in zero page.

[patch 1/1] Do not call close-deblocker since ob_pci_open did not open it.
