[PATCH v2 0/4] Fix sha1_mb failure and testing import()/export()

sha1_mb. patch04 adds a test case for import() and export(). A hash algo's import()/export() can be tested by simply adding .partial = 1 to its corresponding struct hash_testvec where .np > 1. v2: Leverage template[i].np in the test case as suggested by Tim Chen. Rui Wang (4): crypto x86

[PATCH] x86/ioapic: Ignore root bridges without a companion ACPI device

Some PCI root bridges don't have a corresponding ACPI device. This can be the case on some old platforms. Don't call acpi_ioapic_add() on these bridges because they can't support ioapic hotplug. v2: Per Boris's review, removed the unnecessary local var; refined comment Sig
