2006-12-08[PARISC] Unbreak discontigmem mem_init()Kyle McMartin
The `simple' way of walking and checking PageReserved is broken on discontigmem, instead we need to check each range explicitly. (Also rename a few things so they make more sense.) Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>

2006-12-08[PARISC] Delete arch/parisc/mm/kmap.c againMatthew Wilcox
I deleted this file from 2.4 5 years ago. Unfortunately, that change never got merged to Linus and so when we switched to 2.5 it came back and nobody noticed. It's never been built in 2.5/2.6 as it was never in the Makefile. Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>
2006-12-07[PATCH] elf: Always define elf_addr_t in linux/elf.hMagnus Damm
Define elf_addr_t in linux/elf.h. The size of the type is determined using ELF_CLASS. This allows us to remove the defines that today are spread all over .c and .h files.

2006-12-07[PATCH] mm: arch do_page_fault() vs in_atomic()Peter Zijlstra
In light of the recent pagefault and filemap_copy_from_user work I've gone through all the arch pagefault handlers to make sure the inc_preempt_count() 'feature' works as expected. Several sections of code (including the new filemap_copy_from_user) rely on the fact that faults do not take locks under increased preempt count. arch/x86_64 - good arch/powerpc - good arch/cris - fixed arch/i386 - good arch/parisc - fixed arch/sh - good arch/sparc - good arch/s390 - good arch/m68k - fixed arch/ppc - good arch/alpha - fixed arch/mips - good arch/sparc64 - good arch/ia64 - good arch/arm - fixed arch/um - good arch/avr32 - good arch/h8300 - NA arch/m32r - good arch/v850 - good arch/frv - fixed arch/m68knommu - NA arch/arm26 - fixed arch/sh64 - fixed arch/xtensa - good Signed-off-by: Peter Zijlstra <a.p.zijlstra@chello.nl> Acked-by: Nick Piggin <npiggin@suse.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2006-10-27[PATCH] vmlinux.lds: consolidate initcall sectionsAndrew Morton
Add a vmlinux.lds.h helper macro for defining the eight-level initcall table, teach all the architectures to use it. This is a prerequisite for a patch which performs initcall synchronisation for multithreaded-probing.

2006-10-07[PARISC] More pt_regs removalMatthew Wilcox
Remove pt_regs from ipi_interrupt and timer_interrupt. Inline smp_do_timer() into its only caller, and unify the SMP and non-SMP paths. Fixes a profiling bug. Signed-off-by: Matthew Wilcox <matthew@wil.cx>
2006-10-07[PARISC] Make firmware calls irqsafe-ish...Kyle McMartin
There's no reason why we shouldn't be using _irqsave instead of _irq for any of these calls. fwiw, this fixes the "start_kernel(): bug: interrupts were enabled early" message displayed on bootup recently.

2006-10-07[PA-RISC] Fix boot breakageMatthew Wilcox
Conditionals were the wrong way around. Turns out I was booting the wrong kernel when testing the original fix. Signed-off-by: Matthew Wilcox <matthew@wil.cx>

2006-10-05[PA-RISC] Fix time.c for new do_timer() calling conventionMatthew Wilcox
do_timer now wants to know how many ticks have elapsed. Now that we have to calculate that, we can eliminate some of the clever code that avoided having to calculate that. Also add some more documentation. I'd like to thank Grant Grundler for helping me with this. Signed-off-by: Matthew Wilcox <willy@parisc-linux.org>
2006-10-05[PA-RISC] Fix must_check warnings in drivers.cMatthew Wilcox
Panic if we can't register the parisc bus or the root parisc device. There's no way we can boot without them, so let the user know ASAP. If we can't register a parisc device, handle the failure gracefully. Signed-off-by: Matthew Wilcox <willy@parisc-linux.org>
2006-10-05[PA-RISC] Fix parisc_newuname()Matthew Wilcox
The utsname virtualisation broke parisc_newuname compilation. Rewrite the implementation to call sys_newuname() like sparc64 does. Signed-off-by: Matthew Wilcox <willy@parisc-linux.org>
2006-10-05[PA-RISC] Remove warning from pci.cMatthew Wilcox
max() doesn't like comparing an unsigned long and a resource_size_t, so make the local variables resource_size_t too. Signed-off-by: Matthew Wilcox <willy@parisc-linux.org>

filldir_t now takes a u64, not an ino_t. Signed-off-by: Matthew Wilcox <matthew@wil.cx>
2006-10-05[PA-RISC] Fix sys32_sysctlMatthew Wilcox
When CONFIG_SYSCTL_SYSCALL isn't defined, do_sysctl doesn't exist and we fail to link. Fix with an ifdef, the same way sparc64 did. Also add some minor changes to be more like sparc64. Signed-off-by: Matthew Wilcox <matthew@wil.cx>

2006-10-04[PARISC] Fix CONFIG_DEBUG_SPINLOCKMatthew Wilcox
Joel Soete points out that we refer to pa_tlb_lock but only define it if CONFIG_SMP which breaks a uniprocessor build with CONFIG_DEBUG_SPINLOCK enabled. No module refers to pa_tlb_lock, so we can delete the export. Signed-off-by: Matthew Wilcox <willy@parisc-linux.org> Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>

2006-10-04[PARISC] Allow nested interruptsJames Bottomley
Our prior mode of operation didn't allow nested interrupts because it makes the interrupt code much simpler. However, nested interrupts are better for latency. This code uses the EIEM register to simulate level interrupts and thus achieve nesting.

2006-10-04[PARISC] Further updates to timer_interrupt()Grant Grundler
This version (relative to the current tree): o eliminates "while (ticks_elapsed)" loop. It's not needed. o drop "ticks_elapsed" completely from timer_interrupt(). o Estimates elapsed cycles (based on HZ) to see which kind of math we want to use to calculate "cycles_remainder". o Fixes a bug where we would loose a tick if we decided we wanted to skip one interrupt.

2006-10-04[PARISC] Rewrite timer_interrupt() and gettimeoffset() using "unsigned" math.Grant Grundler
It's just a bit easier to follow and timer code is complex enough. So far, only tested on A500-5x (64-bit SMP), ie: gettimeoffset() code hasn't been tested at all. Signed-off-by: Grant Grundler <grundler@parisc-linux.org> Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>
2006-10-04[PARISC] Add new function to start local Interval Timer, start_cpu_itimer()Grant Grundler
I couldn't find where the itimer was getting started for slave CPUs. CPU 0 (master) itimer was started in time_init() (arch/parisc/kernel/time.c). start_cpu_itimer() code was striped from time_init(). Slaves now start their itimer in smp_cpu_init(). This is a first step towards making gettimeoffset() work for SMP. Next step will be to determine the CR16 (cycle counter) offsets for each CPU relative to the master (CPU 0).

2006-10-04[PARISC] Prevent processor_probe() from clobbering cpu_data[0]Grant Grundler

2006-10-04[PARISC] parisc specific kmap API implementation for pa8800James Bottomley
This patch fixes the pa8800 at a gross level (there are still other subtle incoherency issues which can still cause crashes and HPMCs). What it does is try to force eject inequivalent aliases before they become visible to the L2 cache (which is where we get the incoherence problems). A new function (parisc_requires_coherency) is introduced in asm/processor.h to identify the pa8x00 processors (8800 and 8900) which have the issue.

2006-10-04[PARISC] PA7200 also supports prefetch for readKyle McMartin
It seems PA7200 processors also suppress traps on loads to %r0. This means we can prefetch for read on these cpus. Of course, we can't support prefetch for write, since that requires LOAD DOUBLEWORD which was added with PA2.0 Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>
