We have a new x86 HW subarch ID in boot_param, then we use it to select x86_init abstractions. Both boot_param and x86_init are x86 arch specific so I guess we can use them in 8042 driver under CONFIG_X86. Not sure if it is possible to move x86 i8042_platform_init under x86_init (the x86 part). >-----Original Message----- >From: Dmitry Torokhov [mailto:dmitry.torokhov@gmail.com] >Sent: Monday, June 28, 2010 3:45 PM >To: Pan, Jacob jun >Cc: Randy Dunlap; Stephen Rothwell; linux-next@vger.kernel.org; LKML; >linux-input@vger.kernel.org; akpm; chuck.lever@oracle.com; H.
