2006-09-28	[S390] Inline assembly cleanup.	Martin Schwidefsky
	Major cleanup of all s390 inline assemblies. They now have a common coding style. Quite a few have been shortened, mainly by using register asm variables. Use of the EX_TABLE macro helps as well. The atomic ops, bit ops and locking inlines new use the Q-constraint if a newer gcc is used. That results in slightly better code. Thanks to Christian Borntraeger for proof reading the changes.

2006-09-26	[PATCH] bootmem: use MAX_DMA_ADDRESS instead of LOW32LIMIT	Heiko Carstens
	Introduce ARCH_LOW_ADDRESS_LIMIT which can be set per architecture to override the 4GB default limit used by the bootmem allocater within __alloc_bootmem_low() and __alloc_bootmem_low_node(). E.g. s390 needs a 2GB limit instead of 4GB.

2005-07-27	[PATCH] s390: spin lock retry	Martin Schwidefsky
	Split spin lock and r/w lock implementation into a single try which is done inline and an out of line function that repeatedly tries to get the lock before doing the cpu_relax(). Add a system control to set the number of retries before a cpu is yielded. The reason for the spin lock retry is that the diagnose 0x44 that is used to give up the virtual cpu is quite expensive. For spin locks that are held only for a short period of time the costs of the diagnoses outweights the savings for spin locks that are held for a longer timer. The default retry count is 1000.

2005-06-25	[PATCH] s390: improved machine check handling	Heiko Carstens
	Improved machine check handling. Kernel is now able to receive machine checks while in kernel mode (system call, interrupt and program check handling). Also register validation is now performed.

2005-04-19	[PATCH] freepgt: remove MM_VM_SIZE(mm)	Hugh Dickins
	There's only one usage of MM_VM_SIZE(mm) left, and it's a troublesome macro because mm doesn't contain the (32-bit emulation?) info needed. But it too is only needed because we ignore the end from the vma list. We could make flush_pgtables return that end, or unmap_vmas. Choose the latter, since it's a natural fit with unmap_mapping_range_vma needing to know its restart addr. This does make more than minimal change, but if unmap_vmas had returned the end before, this is how we'd have done it, rather than storing the break_addr in zap_details. unmap_vmas used to return count of vmas scanned, but that's just debug which hasn't been useful in a while; and if we want the map_count 0 on exit check back, it can easily come from the final remove_vm_struct loop.

2005-04-16	Linux-2.6.12-rc2v2.6.12-rc2	Linus Torvalds
	Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
