From 6e69d6068cc2aa545544189a1ee4d2e1a32ad591 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Tue, 28 Aug 2007 14:25:32 -0700 Subject: [SPARC64]: Fix type and constant sizes wrt. sun4u IMAP/ICLR handling. Sometimes we were using 32-bit values and the top bits were getting inadvertantly chopped off. This will matter for the forthcoming Fire controller MSI support. Signed-off-by: David S.

Miller" Date: Thu, 30 Aug 2007 22:27:28 -0700 Subject: [SPARC64]: Fix several bugs in MSI handling. 1) sun4{u,v}_build_msi() have improper return value handling. We should always return negative error codes, instead of using the magic value "0" which could in fact be a valid MSI number. 2) sun4{u,v}_build_msi() should return -ENOMEM instead of calling prom_prom() halt with kzalloc() of the interrupt data fails. 3) We 'remembered' the MSI number using a singleton in the struct device archdata area, this doesn't work for MSI-X which can cause multiple MSIs assosciated with one device. Delete that archdata member, and instead store the MSI number in the IRQ chip data area. Signed-off-by: David S.
