From: Michael S. Tsirkin Date: Tue, 14 Jul 2015 23:27:46 +0000 (-0500) Subject: PCI: Restore PCI_MSIX_FLAGS_BIRMASK definition X-Git-Tag: v3.16.35~1496 X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=f666c5e0dda0a6c09f0ecbcd5bf8e3b43c8db8cf;p=thirdparty%2Fkernel%2Fstable.git PCI: Restore PCI_MSIX_FLAGS_BIRMASK definition commit c9ddbac9c89110f77cb0fa07e634aaf1194899aa upstream. 09a2c73ddfc7 ("PCI: Remove unused PCI_MSIX_FLAGS_BIRMASK definition") removed PCI_MSIX_FLAGS_BIRMASK from an exported header because it was unused in the kernel. But that breaks user programs that were using it (QEMU in particular). Restore the PCI_MSIX_FLAGS_BIRMASK definition. [bhelgaas: changelog] Signed-off-by: Michael S.
