2010-09-02powerpc/pseries: Correct rtas_data_buf locking in dlpar codeNathan Fontenot1-13/+29
The dlpar code can cause a deadlock to occur when making the RTAS configure-connector call. This occurs because we make kmalloc calls, which can block, while parsing the rtas_data_buf and holding the rtas_data_buf_lock. This an cause issues if someone else attempts to grab the rtas_data_bug_lock. This patch alleviates this issue by copying the contents of the rtas_data_buf to a local buffer before parsing. This allows us to only hold the rtas_data_buf_lock around the RTAS configure-connector calls.

2010-08-31powerpc: Don't use kernel stack with translation offMichael Neuling1-3/+9
In f761622e59433130bc33ad086ce219feee9eb961 we changed early_setup_secondary so it's called using the proper kernel stack rather than the emergency one. Unfortunately, this stack pointer can't be used when translation is off on PHYP as this stack pointer might be outside the RMO. This results in the following on all non zero cpus: cpu 0x1: Vector: 300 (Data Access) at [c00000001639fd10] pc: 000000000001c50c lr: 000000000000821c sp: c00000001639ff90 msr: 8000000000001000 dar: c00000001639ffa0 dsisr: 42000000 current = 0xc000000016393540 paca = 0xc000000006e00200 pid = 0, comm = swapper The original patch was only tested on bare metal system, so it never caught this problem. This changes __secondary_start so that we calculate the new stack pointer but only start using it after we've called early_setup_secondary. With this patch, the above problem goes away.

2010-08-31powerpc/perf_event: Reduce latency of calling perf_event_do_pendingPaul Mackerras1-12/+11
Commit 0fe1ac48 ("powerpc/perf_event: Fix oops due to perf_event_do_pending call") moved the call to perf_event_do_pending in timer_interrupt() down so that it was after the irq_enter() call. Unfortunately this moved it after the code that checks whether it is time for the next decrementer clock event. The result is that the call to perf_event_do_pending() won't happen until the next decrementer clock event is due. This was pointed out by Milton Miller. This fixes it by moving the check for whether it's time for the next decrementer clock event down to the point where we're about to call the event handler, after we've called perf_event_do_pending. This has the side effect that on old pre-Core99 Powermacs where we use the ppc_n_lost_interrupts mechanism to replay interrupts, a replayed interrupt will incur a little more latency since it will now do the code from the irq_enter down to the irq_exit, that it used to skip. However, these machines are now old and rare enough that this doesn't matter. To make it clear that ppc_n_lost_interrupts is only used on Powermacs, and to speed up the code slightly on non-Powermac ppc32 machines, the code that tests ppc_n_lost_interrupts is now conditional on CONFIG_PMAC as well as CONFIG_PPC32.

2010-08-31powerpc/kexec: Adds correct calling convention for kexec purgatoryMatthew McClintock1-0/+3
Call kexec purgatory code correctly. We were getting lucky before. If you examine the powerpc 32bit kexec "purgatory" code you will see it expects the following: >From kexec-tools: purgatory/arch/ppc/v2wrap_32.S -> calling convention: -> r3 = physical number of this cpu (all cpus) -> r4 = address of this chunk (master only) As such, we need to set r3 to the current core, r4 happens to be unused by purgatory at the moment but we go ahead and set it here as well Signed-off-by: Matthew McClintock <msm@freescale.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

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 <schwidefsky@de.ibm.com>

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.
