2010-08-24[S390] fix tlb flushing vs. concurrent /proc accessesMartin Schwidefsky8-6/+28
The tlb flushing code uses the mm_users field of the mm_struct to decide if each page table entry needs to be flushed individually with IPTE or if a global flush for the mm_struct is sufficient after all page table updates have been done. The comment for mm_users says "How many users with user space?" but the /proc code increases mm_users after it found the process structure by pid without creating a new user process. Which makes mm_users useless for the decision between the two tlb flusing methods. The current code can be confused to not flush tlb entries by a concurrent access to /proc files if e.g. a fork is in progres. The solution for this problem is to make the tlb flushing logic independent from the mm_users field. Signed-off-by: Martin Schwidefsky <[email protected]>

2010-08-23sparc64: Get rid of indirect p1275 PROM call buffer.David S. Miller7-297/+456
This is based upon a report by Meelis Roos showing that it's possible that we'll try to fetch a property that is 32K in size with some devices. With the current fixed 3K buffer we use for moving data in and out of the firmware during PROM calls, that simply won't work. In fact, it will scramble random kernel data during bootup. The reasoning behind the temporary buffer is entirely historical. It used to be the case that we had problems referencing dynamic kernel memory (including the stack) early in the boot process before we explicitly told the firwmare to switch us over to the kernel trap table. So what we did was always give the firmware buffers that were locked into the main kernel image. But we no longer have problems like that, so get rid of all of this indirect bounce buffering. Besides fixing Meelis's bug, this also makes the kernel data about 3K smaller. It was also discovered during these conversions that the implementation of prom_retain() was completely wrong, so that was fixed here as well. Currently that interface is not in use.

2010-08-24powerpc: Initialise paca->kstack before early_setup_secondaryMatt Evans1-3/+3
As early setup calls down to slb_initialize(), we must have kstack initialised before checking "should we add a bolted SLB entry for our kstack?" Failing to do so means stack access requires an SLB miss exception to refill an entry dynamically, if the stack isn't accessible via SLB(0) (kernel text & static data). It's not always allowable to take such a miss, and intermittent crashes will result. Primary CPUs don't have this issue; an SLB entry is not bolted for their stack anyway (as that lives within SLB(0)). This patch therefore only affects the init of secondaries.

2010-08-24powerpc: Fix bogus it_blocksize in VIO iommu codeAnton Blanchard4-7/+8
When looking at some issues with the virtual ethernet driver I noticed that TCE allocation was following a very strange pattern: address 00e9000 length 2048 address 0409000 length 2048 <----- address 0429000 length 2048 address 0449000 length 2048 address 0469000 length 2048 address 0489000 length 2048 address 04a9000 length 2048 address 04c9000 length 2048 address 04e9000 length 2048 address 4009000 length 2048 <----- address 4029000 length 2048 Huge unexplained gaps in what should be an empty TCE table. It turns out it_blocksize, the amount we want to align the next allocation to, was c0000000fe903b20. Completely bogus. Initialise it to something reasonable in the VIO IOMMU code, and use kzalloc everywhere to protect against this when we next add a non compulsary field to iommu code and forget to initialise it.

2010-08-24powerpc: Make rwsem use "long" typeBenjamin Herrenschmidt1-27/+37
This makes the 64-bit kernel use 64-bit signed integers for the counter (effectively supporting 32-bit of active count in the semaphore), thus avoiding things like overflow of the mmap_sem if you use a really crazy number of threads Note: Ideally the type in the structure should be atomic_long_t rather than "long". However, there's some nasty issues with that. It needs to be initialized statically -and- lib/rwsem.c does things like sem->count = RWSEM_UNLOCKED_VALUE; Now, if you mix in the fact that atomic_* types are actually structures with one member and note typedefs of a scalar, it makes its really nasty. So I stuck to what we did before using a long and casts for now. Signed-off-by: Benjamin Herrenschmidt <[email protected]>
