Date: Wed, 25 Apr 2012 17:52:02 +0200 From: Borislav Petkov <bp@...64.org> To: EDAC devel <linux-edac@...r.kernel.org>, LKML <linux-kernel@...r.kernel.org> Cc: Tony Luck <tony.luck@...el.com>, Borislav Petkov <borislav.petkov@....com> Subject: [PATCH 2/3] x86, MCE, AMD: Hide interrupt_enable sysfs node From: Borislav Petkov <borislav.petkov@....com> Depending on whether the box supports the APIC LVT interrupt for thresholding, we want to show the 'interrupt_enable' sysfs node or not. Make that the case by adding it to the default sysfs attributes only if it is supported.
