Subject: [PATCH] s390: use __cpcmd in vmcp_write
X-Git-Tag: v2.6.13-rc4~25^2~75
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3e5ea098446e19175fdee4c2c4ec9366b0217db4;p=linux-2.6

[PATCH] s390: use __cpcmd in vmcp_write

vmcp_write uses GPF_DMA for the memory allocation of the response buffer, so
it can use the low level function __cpcmd directly, no need to call the
wrapper.
