A couple of GSM GPRS PCMCIA cards advertise 16 rather than 8 port sized windows for their serial interface. This breaks our current pcmcia serial driver which ignores any windows that are not 8 bytes. To avoid any regressions on other cards given this driver contains a certain amount of "magic" the patch below looks for 8 byte windows first so will not break existing supported cards (I hope ;)) Patch-by:

Currently metadata writing errors are ignored and not returned from sys_fsync on ext2 and ext3 filesystems. That is, at least ext2 and ext3. Both ext2 and ext3 resort to sync_inode() in their ->sync_inode method, which in turn calls ->write_inode. ->write_inode method has void type, and any IO errors happening inside are lost. Make ->write_inode return the error code? Signed-off-by:

Don't pass CR2 address on alignment faults. They report the address of the last page fault, which is a information leak. Fix this for i386 and x86-64 by passing 0 instead. Pointed out by Zachary Amsden <zach@vmware.com> Signed-off-by:

From: James Cleverdon The value that cpuinfo returns for command 1 in ebx is the physical APIC ID latched when the system comes out of reset. Ordinarily, this is identical to the value in the local APIC's ID register, because nearly all BIOSes accept the HW assigned value. Our systems, made up of individual building blocks, can't do that. Each node boots as a separate system and is joined together by the BIOS. Thus, the BIOS rewrites the local APIC ID register with a new value. Potomac and Nocona chips have a mechanism by which the BIOS writer can change bits 7:5 to match the assigned cluster ID. Bits 2:0 come from the thread ID. However, bits 4:3 are still those latched at reset. Oops! Summary: Large clustered systems can't use cpuid to derive the sibling information. Fix: Use the local APIC ID. That's the value we use to online the CPUs, so it had better be OK. For non-clustered systems, cpuid == local APIC, so nothing but large boxes should be affected. Signed-off-by:

For historical reasons, ppc64 has ended up with two #defines for the size of a large (16M) page: LARGE_PAGE_SHIFT and HPAGE_SHIFT. This patch removes LARGE_PAGE_SHIFT in favour of the more widely used HPAGE_SHIFT. Signed-off-by:

Replace the mmu_context_queue structure with the idr allocator. The mmu_context_queue allocation was quite large (~200kB) so on most machines we will have a reduction in usage. We might put a single entry cache on the front of this so we are more likely to reuse ppc64 MMU hashtable entries that are in the caches. Signed-off-by:
