* [JFFS2] Add erase block summary support (mount time improvement)Ferenc Havasi2005-11-06
| | | | | | | | | | | | | | | | | | The goal of summary is to speed up the mount time. Erase block summary (EBS) stores summary information at the end of every (closed) erase block. It is no longer necessary to scan all nodes separetly (and read all pages of them) just read this "small" summary, where every information is stored which is needed at mount time. This summary information is stored in a JFFS2_FEATURE_RWCOMPAT_DELETE. During the mount process if there is no summary info the orignal scan process will be executed. EBS works with NAND and NOR flashes, too. There is a user space tool called sumtool to generate this summary information for a JFFS2 image.

* {MTD] add support for Intel's "Sibley" flashNicolas Pitre2005-11-06
| | | | | | | | | | | | | This updates the Primary Vendor-Specific Extended Query parsing to version 1.4 in order to get the information about the Configurable Programming Mode regions implemented in the Sibley flash, as well as selecting the appropriate write command code. This flash does not behave like traditional NOR flash when writing data. While mtdblock should just work, further changes are needed for JFFS2 use.

* [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>

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | register_vpa() doesn't actually do a VPA register call it just uses the flags you pass it, so rename it to vpa_call() to be clearer. 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.

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>

| | * | [PATCH] powerpc: Move naca.h to platforms/iseriesDavid Gibson2005-11-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These days, the NACA only exists on iSeries. Therefore, this patch moves naca.h from include/asm-ppc64 to arch/powerpc/platforms/iseries. There was one file including naca.h outside of platforms/iseries - arch/ppc64/kernel/udbg_scc.c. However, that's obviously a hangover from older days. The include is not necessary, so this patch simply removes it. Built and booted on iSeries, built for G5 (which uses udbg_scc.o).
