X-Git-Tag: v2.6.22-rc1~1039^2~26 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=032de8e2fe3c0eec5fb0ffe4d38aa602dad397dc;p=pandora-kernel.git MSI: Give archs the option to free all MSI/Xs at once. This patch introduces an optional function, arch_teardown_msi_irqs(), which gives an arch the opportunity to do per-device teardown for MSI/X. If that's not required, the default version simply calls arch_teardown_msi_irq() for each msi irq required. arch_teardown_msi_irqs() is simply passed a pdev, attached to the pdev is a list of msi_descs, it is up to the arch to free the irq associated with each of these as appropriate. For archs that _don't_ implement arch_teardown_msi_irqs(), all msi_descs with irq == 0 are considered unallocated, and the arch teardown routine is not called on them.
