* [PATCH] ARM: 2709/1: Systems with PCMCIA should also see IDE options (for ↵David Brownell2005-06-121-1/+3
| | | | | | | | | | | | | | | | | | CompactFlash memories) Patch from David Brownell The ARM generic Kconfig filters out IDE options ... except for an error prone ARMload of special cases. This adds one general case to the systems that will offer IDE options: kernels with PCMCIA support, which probably want to use IDE to access CompactFlash cards. This might allow many (most?) of the other cases to disappear, for systems that only see IDE hardware through CF cards. Right now this one patch is used to gate access to CF cards, including MicroDrives, for both omap_cf and at91_cf drivers.

* [PATCH] ppc32: Fix nasty sleep/wakeup problemBenjamin Herrenschmidt2005-06-091-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Despite all the care lately in making the powermac sleep/wakeup as robust as possible, there is still a nasty related to the use of cpufreq on PMU based machines. Unfortunately, it affects paulus old powerbook so I have to fix it :) We didn't manage to understand what is precisely going on, it leads to memory corruption and might have to do with RAM not beeing properly refreshed when a cpufreq transition is done right before the sleep. The best workaround (and less intrusive at this point) we could come up with is included in this patch. We basically do _not_ force a switch to high speed on suspend anymore (that is what is causing the problem) on those machines. We still force a speed switch on wakeup (since we don't know what speed we are coming back from sleep at, and that seems to work fine). Since, during this short interval, the actual CPU speed might be incorrect, we also hack around by multiplying loops_per_jiffy by 2 (max speed factor on those machines) during early wakeup stage to make sure udelay's during that time aren't too short. For after 2.6.12, we'll change udelay implementation to use the CPU timebase (which is always constant) instead like we do on ppc64 and thus get rid of all those problems.

|/ | | | | | | | | | | | | | current->blocked will be set to the value of current->thread_info->flags if the cmpxchg to update thread_info->flags fails. For performance reasons the store into current->blocked was placed in the cmpxchg loop. However, the cmpxchg overwrites the register holding the value to be stored. In the rare case of a retry the value of thread_info->flags will be written into current->blocked. The fix is to use another register so that the register containing the current->blocked value is not overwritten.

* [PATCH] ia64: fix floating-point preemption problemPeter Chubb2005-06-082-1/+16
| | | | | | | | | | | | | | | | | | | | | There've been reports of problems with CONFIG_PREEMPT=y and the high floating point partition. This is caused by the possibility of preemption and rescheduling on a different processor while saving or restioirng the high partition. The only places where the FPU state is touched are in ptrace, in switch_to(), and where handling a floating-point exception. In switch_to() preemption is off. So it's only in trap.c and ptrace.c that we need to prevent preemption. Here is a patch that adds commentary to make the conditions clear, and adds appropriate preempt_{en,dis}able() calls to make it so. In trap.c I use preempt_enable_no_resched(), as we're about to return to user space where the preemption flag will be checked anyway.

* [PATCH] uml: fix strace -fJeff Dike2005-06-081-1/+6
| | | | | | | | | | | | | | | It turns out that we need to check for pending signals when a newly forked process is run for the first time. With strace -f, strace needs to know about the forked process before it gets going. If it doesn't, then it ptraces some bogus values into its registers, and the process segfaults. So, I added calls to interrupt_end, which does that, plus checks for reschedules. There shouldn't be any of those, but x86 does the same thing, so I'm copying that behavior to be safe.
