2012-05-12sparc32: Un-btfixup {pte,pmd,pgd}_clear().David S. Miller
Also we can remove BTFIXUPCALL_SWAPO0G0 as that is no longer used. This was rather amusing, we were setting the btfixup vectors based upon cpu type but all to the same exact generic srmmu routines. Furthermore, we were inconsistently marking the fixup as either BTFIXUPCALL_SWAPO0G0 or BTFIXUPCALL_NORM. What a mess, glad we could untangle this stuff. Signed-off-by: David S. Miller <davem@davemloft.net>
2012-05-12SPEAr: Call clk_prepare() before calling clk_enableViresh Kumar
With common clock framework, it is must to call clk_{un}prepare() before/after clk_{dis}enable. This patch fixes this for SPEAr timer. Signed-off-by: Viresh Kumar <viresh.kumar@st.com> Reviewed-by: Mike Turquette <mturquette@linaro.org>
2012-05-12SPEAr: Add DT bindings for SPEAr's timerViresh Kumar
All SPEAr SoC's use ST's Timer module. This patch adds device tree probing capability for that. Signed-off-by: Viresh Kumar <viresh.kumar@st.com> Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2012-05-12sparc32: drop btfixup for check_pgt_cacheSam Ravnborg
It is a noop for srmmu - so use a define as sparc64 does. And drop all sparc callers - no need to confuse our-self be calling a noop function. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2012-05-12sparc32: drop btfixup for switch_mmSam Ravnborg
This revealed that the implementation of switch_mm had a bogus extra argument. No harm as said argument was never used - but confusing. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2012-05-12sparc32: code cleanup in floppy glueSam Ravnborg
Small cleanup to improve readability. Dropped one test for sparc_cpu_model - we already know that only sun4m support floppy. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2012-05-12sparc32: fix warning in floopy glueSam Ravnborg
Fix following warning: arch/sparc/include/asm/floppy_32.h:342:5: warning: 'op' may be used uninitialized in this function The warning are legitimite and we can end up using op uninitialized.

2012-05-12sparc32: drop prom version check in head_32.SSam Ravnborg
We already sorted out if we are a sun4/sun4c and halted. So no need to check the prom version as we know this is a v2 or v3 as sun4m, sun4d etc. does not use a v1 prom. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>

2012-05-12ARM: 7417/1: vfp: ensure preemption is disabled when enabling VFP accessWill Deacon
The vfp_enable function enables access to the VFP co-processor register space (cp10 and cp11) on the current CPU and must be called with preemption disabled. Unfortunately, the vfp_init late initcall does not disable preemption and can lead to an oops during boot if thread migration occurs at the wrong time and we end up attempting to access the FPSID on a CPU with VFP access disabled. This patch fixes the initcall to call vfp_enable from a non-preemptible context on each CPU and adds a BUG_ON(preemptible) to ensure that any similar problems are easily spotted in the future.
