Looks like a workaround for old bogus OF bitrot... This fixes it and hence fixes boot on some performa machines. Signed-off-by: NBenjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: NPaul Mackerras <paulus@samba.org>

On detection of an EEH error, some Power4 systems seem to occasionally want to be reset twice before they report themselves as fully recovered. This patch re-arranges the code to attempt additional resets if the first one doesn't take. Signed-off-by: NLinas Vepstas <linas@austin.ibm.com> Signed-off-by: NPaul Mackerras <paulus@samba.org>

Noticed that the U3_*CFA macros have some typos: #define U3_HT_CFA0(devfn, off) \ ((((unsigned long)devfn) << 8) | offset) (refers to offset rather than off) #define U3_AGP_CFA0(devfn, off) \ ((1 << (unsigned long)PCI_SLOT(dev_fn)) \ | (((unsigned long)PCI_FUNC(dev_fn)) << 8) \ (refers to dev_fn rather than devfn) Things happen to work, but there doesn't seem to be any reason these shouldn't be functions. Overall behavior should be unchanged. Signed-off-by: NNathan Lynch <ntl@pobox.com> Signed-off-by: NPaul Mackerras <paulus@samba.org>

When there is a PCI-X mode 2 capable device behind the HT<->PCI-X bridge, the pci core decides that the device has the extended 4K config space, even though the bus is not operating in mode 2. This is because the u3_ht pci ops silently accept offsets greater than 255 but use only the 8 least significant bits, which means reading at offset 0x100 gets the data at offset 0x0, and causes confusion for lspci. Reject accesses to configuration space offsets greater than 255. Signed-off-by: NNathan Lynch <ntl@pobox.com> Signed-off-by: NPaul Mackerras <paulus@samba.org>

Ulrich Weigand found a bug with the current version of the asm-powerpc/ptrace.h that prevents building at least the SPU target version of gdb, since some ptrace opcodes are not defined. The problem seems to have originated in the merging of 32 and 64 bit versions of that file, the problem is that some opcodes are only valid on 64 bit kernels, but are also used by 32 bit programs, so they can't depends on the __powerpc64__ symbol.

Update to the PowerPC PCI error recovery code. Add code to enable MMIO if a device driver reports that it is capable of recovering on its own. One anticipated use of this having a device driver enable MMIO so that it can take a register dump, which might then be followed by the device driver requesting a full reset.

This abstracts the operations used in the bootwrapper, and defines the operations needed for the bootwrapper to run on an OF platform. The operations have been divided up into platform ops (platform_ops), firmware ops (fw_ops), device tree ops (dt_ops), and console ops (console_ops). The proper operations will be hooked up at runtime to provide the functionality that you need. Signed-off-by: NMark A. Greer <mgreer@mvista.com> Signed-off-by: NPaul Mackerras <paulus@samba.org>

There are various places where we want to extract an unsigned long value from a device-tree property that can be 1 or 2 cells in length. This replaces some open-coded calculations, and one place where we assumed without checking that properties were the length we wanted, with a little of_read_ulong() helper.

Add support for new hardware and bumps the version to 3.6.10. It seems there were several changes introduced including soft_irq. I decided to bump the major number to reflect these changes.

MIPS asm/page.h unconditionally includes <asm-generic/memory_model.h>, which doesn't exist in userspace. Move an #endif /* __KERNEL__ */ down a few lines to prevent that.

There's useful stuff in <linux/timex.h> but <asm/timex.h> has nothing for userspace. Stop exporting it, and include it only from within the existing #ifdef __KERNEL__ part of <linux/timex.h> This fixes a 'make headers_check' failure on i386 because asm-i386/timex.h includes both asm-i386/tsc.h and asm-i386/processor.h, neither of which are exported to userspace.

We don't need any of this crap included from the user-visible part of nfs_fs.h -- remove it all. In fact, we probably don't need anything but NFS_SUPER_MAGIC to be defined; is there any need for anything else? And magic numbers should probably move to <linux/magic.h> rather than being strewn across various fs-specific include files which exist in userspace for solely that purpose. With this patch, 'make header_check' works again at least on PowerPC.
