Preallocate bootmem memory for the PS3 frame buffer device, which needs a large block of physically-contiguous memory. The size of this memory block is configurable: - The config option CONFIG_FB_PS3_DEFAULT_SIZE_M allows to specify the default amount of memory (in MiB) allocated to the virtual frame buffer. - The early boot parameter `ps3fb=xxx' allows to override the default value. It will be rounded up to a multiple of 1 MiB, if needed.

I noticed that almost all architectures implemented exactly the same sys32_sysinfo... except parisc, where a bug was to be found in handling of the uptime. So let's remove a whole whack of code for fun and profit. Cribbed compat_sys_sysinfo from x86_64's implementation, since I figured it would be the best tested. This patch incorporates Arnd's suggestion of not using set_fs/get_fs, but instead extracting out the common code from sys_sysinfo.

As Andi pointed out: CONFIG_GENERIC_ISA_DMA only disables the ISA DMA channel management. Other functionality may still expect GFP_DMA to provide memory below 16M. So we need to make sure that CONFIG_ZONE_DMA is set independent of CONFIG_GENERIC_ISA_DMA. Undo the modifications to mm/Kconfig where we made ZONE_DMA dependent on GENERIC_ISA_DMA and set theses explicitly in each arches Kconfig. Reviews must occur for each arch in order to determine if ZONE_DMA can be switched off. It can only be switched off if we know that all devices supported by a platform are capable of performing DMA transfers to all of memory (Some arches already support this: uml, avr32, sh sh64, parisc and IA64/Altix). In order to switch ZONE_DMA off conditionally, one would have to establish a scheme by which one can assure that no drivers are enabled that are only capable of doing I/O to a part of memory, or one needs to provide an alternate means of performing an allocation from a specific range of memory (like provided by alloc_pages_range()) and insure that all drivers use that call. In that case the arches alloc_dma_coherent() may need to be modified to call alloc_pages_range() instead of relying on GFP_DMA.

When we do full FP emulation its possible that we need to post a SIGFPE based on the results of the emulation. The previous code ignored this case completely. Additionally, the Soft_emulate_8xx case had two issues. One, we should never generate a SIGFPE since the code only does data movement. Second, we were interpreting the return codes incorrectly, it returns 0 on success, 1 on illop and -EFAULT on a data access error. Signed-off-by: NKumar Gala <galak@kernel.crashing.org>

Anytime we are emulating an instruction we are going to be doing some form of get_user() to get the instruction image to decode. Since get_user() might sleep we need to ensure we have interrupts enabled or we might see something like: Debug: sleeping function called from invalid context at arch/powerpc/kernel/traps.c:697 in_atomic():0, irqs_disabled():1 Call Trace: [D6023EB0] [C0007F84] show_stack+0x58/0x174 (unreliable) [D6023EE0] [C0022C34] __might_sleep+0xbc/0xd0 [D6023EF0] [C000D158] program_check_exception+0x1d8/0x4fc [D6023F40] [C000E744] ret_from_except_full+0x0/0x4c --- Exception: 700 at 0x102a7100 LR = 0xdb9ef04 However, we want to ensure that interrupts are disabled when handling a trap exception that might be used for a kernel breakpoint.

Some instruction tracing tools use the RI (recoverable interrupt) bit in the MSR to indicate when it's safe to single-step. Currently we clear RI after restoring r13 when returning to userspace. However, if we single-step past the point where r13 is restored, we'll corrupt r13 in the exception entry code and not restore it. This moves the clearing of RI to just before r13 is restored so this doesn't happen. Signed-off-by: NPaul Mackerras <paulus@samba.org>

To the issue: some point during 2.6.20 development, Paul Mackerras introduced the "lazy IRQ disabling" patch (very cool work, BTW). In that patch, the performance monitor unit exception was marked as "maskable", in the sense that if interrupts were soft-disabled, that exception could be ignored. This broke my PowerPC profiling code. The symptom that I see is that a varying number of interrupts (from 0 to $n$, typically closer to 0) get delivered, when, in reality, it should always be very close to $n$. The issue stems from the way masking is being done. Masking in this fashion seems to work well with the decrementer and external interrupts, because they are raised again until "really" handled. For the PMU, however, this does not apply (at least on my Xserver machine with a 970FX processor). If the PMU exception is not handled, it will _not_ be re-raised (at least on my machine). The documentation states that the PMXE bit in MMCR0 is set to 0 when the PMU exception is raised. However, software must re-set the bit to re-enable PMU exceptions. If the exception is ignored (as currently) not only is that interrupt lost, but because software does not re-set PMXE, the PMU registers are "frozen" forever. [This patch means that performance monitor exceptions are taken and handled even if irqs are off, as long as some other interrupt hasn't come along and caused interrupts to be hard-disabled. In this sense the PMU exception becomes like an NMI. The oprofile code for most powerpc processors does nothing that is unsafe in an NMI context, but the Cell oprofile code does a spin_lock_irqsave. However, that turns out to be OK because Cell doesn't actually use the performance monitor exception; performance monitor interrupts come in as a regular interrupt on Cell, so will be disabled when irqs are off. -- paulus.] Signed-off-by: NPaul Mackerras <paulus@samba.org>
