* [JFFS2] Debug code clean up - step 3Artem B. Bityutskiy2005-11-06

* [JFFS2] Fix slab panicArtem B. Bityutskiy2005-11-06
| | | | | | | | | | When JFFS22 is unable to read the root inode, the bad root inode object is not freed and remains sticked in the jffs2_i slab cache. When we further try to free the slab cache (e.g., on rmmod jffs2), slab allocator subsystem panics. Fix this bug. Signed-off-by: Artem B.

* [JFFS2] Use f->target instead of f->dents for symlink targetArtem B. Bityutskiy2005-11-06
| | | | | | | | | | JFFS2 uses f->dents to store the pointer to the symlink target string (in case the inode is symlink). This is somewhat ugly to use the same field for different reasons. Introduce distinct field f->target for this purpose. Note, f->fragtree, f->dents, f->target may probably be put in a union. Signed-off-by: Artem B.

| * [PATCH] nvidiafb: Geforce 7800 series support addedCalin A. Culianu2005-11-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for the Nvidia Geforce 7800 series of cards to the nvidiafb framebuffer driver. All it does is add the PCI device id for the 7800, 7800 GTX, 7800 GO, and 7800 GTX GO cards to the module device table for the nvidiafb.ko driver, so that nvidiafb.ko will actually work on these cards. I also added the relevant PCI device ids to linux/pci_ids.h I tested it on my 7800 GTX here and it works like a charm. I now can get framebuffer support on this card! Woo hoo!! Nothing like 200x75 text mode to make your eyes BLEED. ;) Signed-off-by: Linus Torvalds <torvalds@osdl.org>

| | * | powerpc: Fix vmlinux.lds.S for 32-bitPaul Mackerras2005-11-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We can't currently use asm-ppc/page.h in vmlinux.lds.S, so until we have a merged page.h, define PAGE_SIZE and KERNELBASE locally. Also gets rid of some dynamic executable cruft that we had for 32-bit. With -Ttext=$(KERNELBASE) this didn't cause any problem, but when we changed to putting . = KERNELBASE in the vmlinux.lds.S this cruft caused the text to get linked at 0xa0 instead of 0xc0000000.

But it's not _quite_ right. The first problem is we calculate the number of registers with: nregs = sizeof(struct pt_regs) / sizeof(ELF_GREG_TYPE) For a 32-bit process on a 64-bit kernel that's bogus because the registers are 64 bits, but ELF_GREG_TYPE is u32, so nregs == 88 which is wrong. The other problem is the memset, which assumes a struct pt_regs is smaller than a struct elf_regs. For a 32-bit process on a 64-bit kernel that's false. The fix is to calculate the number of regs using sizeof(unsigned long), which should always be right, and just memset the whole damn thing _before_ copying the registers in.

We can then define register_vpa() and unregister_vpa() which are both simple wrappers around vpa_call(). (we'll need unregister_vpa() for kexec soon) We can then cleanup vpa_init(), and because vpa_init() is only called from platforms/pseries we remove the definition in asm-ppc64/smp.h.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's a few places already, and soon will be more, where we synthesise branch instructions at runtime.

But we've already got <asm/page.h> in the linker script, so we can just use KERNELBASE directly. That means if we ever change KERNELBASE there's one less place to change it. And we can set the entry point with ENTRY(). There are zero differences from "readelf -a vmlinux" with or without this patch. Signed-off-by: Michael Ellerman <michael@ellerman.id.au>

The only thing that's really changed is that we now allocate crash_notes properly on PPC32. It's address is exported via sysfs, so it's not correct for it to be a pointer. I've also removed some of the "we don't use this" comments, because they're wrong (or perhaps were referring only to arch code). Signed-off-by: Michael Ellerman <michael@ellerman.id.au>
