Date: Sat, 02 Apr 2011 02:22:44 -0400 From: Len Brown <lenb@...nel.org> To: linux-pm@...ts.linux-foundation.org Cc: linux-kernel@...r.kernel.org, Len Brown <len.brown@...el.com>, x86@...nel.org, stable@...nel.org Subject: [PATCH 02/18] x86 idle floppy: deprecate disable_hlt() From: Len Brown <len.brown@...el.com> Plan to remove floppy_disable_hlt in 2.6.40, an ancient workaround with comments that it should be removed. This allows us to remove clutter and a run-time branch from the idle code. WARN_ONCE() on invocation until it is removed. cc: x86@...nel.org cc: stable@...nel.org Signed-off-by: Len Brown <len.brown@...el.com> --- Documentation/feature-removal-schedule.txt | 8 ++++++++ drivers/block/floppy.c | 1 + 2 files changed, 9 insertions(+), 0 deletions(-) diff --git a/Documentation/feature-removal-schedule.txt b/Documentation/feature-removal-schedule.txt index b3f35e5..54db467 100644 --- a/Documentation/feature-removal-schedule.txt +++ b/Documentation/feature-removal-schedule.txt @@ -6,6 +6,14 @@ be removed from this file. --------------------------- +What: x86 floppy disable_hlt +When: 2.6.40 +Why: ancient workaround of dubious utility clutters the + code used by everybody else. +Who: Len Brown <len.brown@...el.com> + +--------------------------- + What: PRISM54 When: 2.6.34 diff --git a/drivers/block/floppy.c b/drivers/block/floppy.c index 77fc76f..41ea03f 100644 --- a/drivers/block/floppy.c +++ b/drivers/block/floppy.c @@ -1038,6 +1038,7 @@ static void floppy_disable_hlt(void) { unsigned long flags; + WARN_ONCE(1, "floppy_disable_hlt() scheduled for removal in 2.6.40"); spin_lock_irqsave(&floppy_hlt_lock, flags); if (!hlt_disabled) { hlt_disabled = 1; -- 1.7.5.rc0 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
