* Fix a (harmless) typo in the SMP save_and_cli definition. Also, markKanoj Sarcar2000-07-171-1/+1
| | | | | the irqlock as not held by anyone initially. This allows SMP kernels to boot up.
* Merge with Linux 2.4.0-test5-pre1. This works again on Origin UP.Ralf Baechle2000-07-151-16/+11
| | | | The IP22 cache bugs which are plaguing some machines are still unfixed.
* Portability cleanup as required by Linus.Ralf Baechle2000-07-151-0/+2
|
* Another reversed condition.Ralf Baechle2000-07-131-3/+3

* Fixup the recent ELF loader changes which were toast ...Ralf Baechle2000-07-131-1/+2

* ELF loader changes / cleanup as discussed on linux-kernel.Ralf Baechle2000-07-121-4/+16

* Merge with Linux 2.4.0-test3-pre8. Linus has accepted most of whatRalf Baechle2000-07-101-3/+5
| | | | | I've sent him, so we're very close to full integration of the MIPS port into his sources.
* Kill warnings in the 64-bit kernel.Ralf Baechle2000-07-092-13/+36
|
* Cast away some warning like the other architectures do.Ralf Baechle2000-07-091-22/+19

* Merge with Linux 2.4.0-test3-pre5. 64-bit kernel are still notRalf Baechle2000-07-081-2/+3
| | | | -Werror clean.
* Merge with 2.4.0-test3-pre4.Ralf Baechle2000-07-083-8/+14

* Fix VMALLOC_END so that all the translations can be held in the pairKanoj Sarcar2000-07-061-1/+1
| | | | of page tables that manage the vmalloc space.
* Vmalloc/vfree fixes: use swapper_pg_dir[0] for the vmalloc rangeKanoj Sarcar2000-07-062-3/+8
| | | | | | translations, use a kernel pmd table that points into the kptbl[]. This is to make the generic part of vmalloc()/vfree() find pgd/pmd/pte that it expects.
* Make flush_icache_page() nicer.Ulf Carlsson2000-07-051-1/+6
|
* Rewrite __udelay() once again. The old code was possibly resulting inRalf Baechle2000-07-041-9/+8
| | | | | ``forbidden or unknown register spilled'' compile errors with error line numbers pointing to some unrelated line.
* flush_icache_page takes struct page * as argument as opposed toUlf Carlsson2000-07-041-1/+1
| | | | flush_cache_page that still takes unsigned long.
* Same for MIPS64.Ulf Carlsson2000-07-021-1/+2
|
* Delete pte/pmd_free_kernel (unused), fix kptbl[] declaration, removeKanoj Sarcar2000-06-301-7/+1
| | | | silly check in pmd_alloc_kernel.
* Implement a functional vmalloc(). THe vmalloc range address translationsKanoj Sarcar2000-06-302-46/+18
| | | | | | | | are stashed in an array of page tables, starting from kptbl[]. The fast tlbmiss handler quickly checks to see if the faulting address is in the vmalloc range, and if so, it uses the translations in the kptbl to update the tlbs. Still to do: tlb invalid faults in the vmalloc range needs to be handled properly.
* Tlb miss handling updates: need to fill in the processor id only onceKanoj Sarcar2000-06-291-4/+15
| | | | during bootup.
* Add in the CONFIG_NUMA option for IP27s (distinct from DISCONTIGMEM whichKanoj Sarcar2000-06-271-0/+2
| | | | | might also be used by platforms with memory holes, but uniform access times). CONFIG_NUMA special code will probably make its way into generic kernel.
* Explain pgd/pmd allocation failure strategies. Create a global bad-pmd-table,Kanoj Sarcar2000-06-271-16/+9
| | | | | | | distinct from invalid-pmd-table for use during pmd allocation failure (so as to differentiate pgd_bad and pgd_none). The bad page table must have invalid pte entries to catch any user references to the range of virtual addresses it covers.
* Delete pmd_present/pgd_present. Explain pgd/pmd/pte allocation andKanoj Sarcar2000-06-261-7/+11
| | | | | initialization. Make sure to allocate only one page for the page table (prevent memory leaks), since only one page is freed up.
* Merge with Linux 2.4.0-test2.Ralf Baechle2000-06-251-0/+5
|
* Fix the number of open file resource limit. With the old limit, portmapKanoj Sarcar2000-06-201-1/+1
| | | | would core dump as soon as someone (rpc.mountd) wanted to talk to it.
* Fix struct stat64 in the 32-bit kernel and struct stat in the 64-bitRalf Baechle2000-06-201-14/+10
| | | | | kernel to match each other and the the glibc definition. The glibc part of this change has been sent to Andreas.
* Make it compile again.Ralf Baechle2000-06-201-2/+0
|
* R3000 cache handling. flush_icache_page now actually flushesRalf Baechle2000-06-202-7/+6
| | | | something.
* Merge with 2.4.0-test1-ac21 + pile of MIPS cleanups to make mergingRalf Baechle2000-06-191-25/+26
| | | | | possible. Chainsawed RM200 kernel to compile again. Jazz machine status unknown.
* Merge with 2.4.0-test1.Ralf Baechle2000-06-162-71/+110

* When doing kernel text replication, make sure we do not scribble onKanoj Sarcar2000-06-131-0/+1
| | | | | top of the replicated kernel text thinking it is unused memory. This lets us get to multiuser on a replicated kernel text system.
* Have the slave bootstrap code actually look at the text and data serverKanoj Sarcar2000-06-091-2/+2
| | | | | nasids that the master nasid found for it. Sanitize the replication procedures.
* Add in the hooks to do kernel text replication. Now start debugging thisKanoj Sarcar2000-06-091-0/+2
| | | | code.
* Each node needs to have a structure that the master nasid fills up toKanoj Sarcar2000-06-092-0/+31
| | | | | tell it where to get the kernel data from (ie, which nasid holds the kernel data). Remove debug cruft from head.S.
* Need to have the nasid of the boot/master node for future uses.Kanoj Sarcar2000-06-091-0/+2

* SMP Mapped kernel fixes to go along with the new layout. Use properlyKanoj Sarcar2000-06-081-0/+3
| | | | | massaged bootstrap address so that the PRM launches the slaves into legal code.
* Mapped kernel changes: create elf sections as close as possible toKanoj Sarcar2000-06-081-0/+15
| | | | | IRIX, to get the same kind of loader behavior. Read comments in mapped_kernel.h for more details.
* Get the mapped kernel working for SMP kernels. While launching slaves,Kanoj Sarcar2000-06-062-1/+25
| | | | | pass the proper address for the slave bootstrap routine based on where the kernel is compiled at.
* Get some type definitions into their rightful places for wider usage.Kanoj Sarcar2000-06-062-0/+3
|
* Make __kernel_caddr_t32 32-bitUlf Carlsson2000-06-061-1/+1
|
* Most of the kernel arrays/data structures and low level proceduresKanoj Sarcar2000-06-022-3/+3
| | | | | now accept the kernel assigned cpuid (instead of the prom assigned id) as input/index. The only exception is the early boot up code.
* Fix some type definitions, add a new field in the per-processor dataKanoj Sarcar2000-06-022-1/+2
| | | | | area to store the PROM assigned cpuid that is used by most of the IP27 kernel and prom data strucutures.
* Make __kernel_clock_t 64 bit.Ralf Baechle2000-05-261-1/+1
|
* This should resolve most of the offset.h issues which popped up lately, I hope.Harald Koerfgen2000-05-262-5/+6
| | | | | | | | | * #include <asm/offset.h> #ifdef'd: init/main.c and $(arch)/tools/offset.c compile without include/asm-$(ARCH)/offset.h. * include/asm-$(ARCH)/offset.h is now depending on $(TOPDIR)/.config: offset.h is beeing rebuilt when .config changes. Please don't count on that, makedep doesn't do it's job very well in this case and objects depending on offset.h aren't neccesarily rebuilt :(
* First cut of TLB handlers in assembler. I'm not usingUlf Carlsson2000-05-251-2/+8
| | | | | | | | | the context register as it should be used, but let's look into that later. If there is a problem with the code it will crash after right after freeing unused kernel memery. I have this code tested on both UP and SMP though.
* Further stresstesting revealed weaknesses in my first proposal.Harald Koerfgen2000-05-241-0/+1
| | | | This one survives "make distclean" and "make dep clean vmlinux".
