From: Milton Miller Date: Fri, 10 Oct 2008 01:56:32 +0000 (+0000) Subject: powerpc/xics: Change *_xirr_info_set() prototype to avoid casts X-Git-Tag: v2.6.28-rc1~569^2~20 X-Git-Url: http://www.pilppa.org/gitweb/gitweb.cgi?a=commitdiff_plain;h=9dc2d44113d1521d8ead8e89e0772c0957b093c2;p=linux-2.6-omap-h63xx.git powerpc/xics: Change *_xirr_info_set() prototype to avoid casts The xirr is 32 bits in hardware, but the hypervisor requries the upper bits of the register to be clear on the hcall. By changing the type from signed to unsigned int we can drop masking it back to 32 bits.
