It's useful to have access to struct ipic handle that just got created in ipic_init(). For example, if we want to setup an external IRQ with out a device node we need access ipic->irqhost to create the virtual to HW IRQ mapping and to set the IRQ sense. With this we can mimic the old sense array concept that existed in arch/ppc. Signed-off-by:Kumar Gala <galak@kernel.crashing.org>

It's possibly that we get an reset requestion when interrupts are disabled. (For example an oops in an interrupt handler). Therefor, we can't call ioremap in the reset function. Moving the ioremap of the registers we need access to an arch_initcall helps the problem. However we still have a window between boot and the arch_initcall in which the register pointer will not be setup and thus we spin if the reset function is called. If one needs to ensure even this case is covered, look at use of the watchdog provided on 83xx to reset the processor. Signed-off-by: -

Updated MATH_EMULATION depends to be on PPC_MPC832x instead of PPC_83xx. Only the the MPC832x has no floating point unit in the core. Updated the other 83xx defconfigs that got math emulation turned on incorrectly. Signed-off-by:

- Drivers will not rely on the PCI config space value, as they've already been conditioned to rely on the irq field in "struct pci_dev". - The virq value may not be < 256 as it has been remapped. - The PCI config space should reflect the hardware configuration, which is not being changed. We are only creating a virtual irq mapping that exists in the kernel only. One would never expect the PCI hardware to generate the "virq" interrupt. Signed-off-by:

I often test new versions of glibc by doing: LD_LIBRARY_PATH=/XXX/lib /XXX/lib/ld.so.1 <binary> One test case ended up SEGV'ing. Upon closer inspection ld.so was loaded at 0x8000000 (128MB) with the heap right after it. Since we normally link binaries at 0x10000000 (256MB) we only had about 128MB of space for the heap: 00100000-00103000 r-xp 00100000 00:00 0 [vdso] 08000000-0801e000 r-xp 00000000 00:01 33079 /lib/ld-2.5.so 0802d000-0802f000 rwxp 0001d000 00:01 33079 /lib/ld-2.5.so 0802f000-08050000 rwxp 0802f000 00:00 0 [heap] 0fe91000-0ffd9000 r-xp 00000000 00:01 33082 /lib/libc-2.5.so 0ffd9000-0ffe8000 ---p 00148000 00:01 33082 /lib/libc-2.5.so 0ffe8000-0ffea000 r--p 00147000 00:01 33082 /lib/libc-2.5.so 0ffea000-0ffed000 rwxp 00149000 00:01 33082 /lib/libc-2.5.so 10000000-10004000 r-xp 00000000 00:01 76 /bin/sleep 10013000-10014000 rwxp 00003000 00:01 76 /bin/sleep ffb41000-ffb56000 rw-p ffb41000 00:00 0 [stack] One way to fix this is move ELF_ET_DYN_BASE from 0x08000000 to 0x20000000. This allows 128MB for the binary (hopefully enough for even the most crazy c++ apps), and with our current layout we will grow the heap up and the stack down, allowing potentially gigabytes of heap: 00100000-00103000 r-xp 00100000 00:00 0 [vdso] 0fe8a000-0ffd3000 r-xp 00000000 00:01 3350 /lib/tls/libc-2.3.6.so 0ffd3000-0ffe3000 ---p 00149000 00:01 3350 /lib/tls/libc-2.3.6.so 0ffe3000-0ffea000 r--p 00149000 00:01 3350 /lib/tls/libc-2.3.6.so 0ffea000-0ffee000 rwxp 00150000 00:01 3350 /lib/tls/libc-2.3.6.so 10000000-10004000 r-xp 00000000 00:01 76 /bin/sleep 10013000-10014000 rwxp 00003000 00:01 76 /bin/sleep 20000000-20018000 r-xp 00000000 00:01 3478 /lib/ld-2.3.6.so 20028000-20029000 r--p 00018000 00:01 3478 /lib/ld-2.3.6.so 20029000-2002a000 rwxp 00019000 00:01 3478 /lib/ld-2.3.6.so 2002a000-2004b000 rwxp 2002a000 00:00 0 [heap] ffd67000-ffd7c000 rw-p ffd67000 00:00 0 [stack] Signed-off-by:

The current PDA code, which went in in post 2.6.19 has a flaw in that it doesn't correctly cycle the GDT and %GS segment through the boot PDA, the CPU PDA and finally the per-cpu PDA. The bug generally doesn't show up if the boot CPU id is zero, but everything falls apart for a non zero boot CPU id. The basically kills voyager which is perfectly capable of doing non zero CPU id boots, so voyager currently won't boot without this. The fix is to be careful and actually do the GDT setups correctly.
