[PATCH] kbuild: Disable depmod in cross-compile kernel build
When building embedded systems in a cross-compile environment and populating a target's file system image, we don't want to run the depmod on the host as we may be building for a completely different architecture. Since there's no such thing as a cross-depmod, we just disable running depmod in the cross-compile case and we just run depmod on the target at bootup.

[PATCH -rt] Disable lpptest on !Linux hosts
Sadly people keep wanting to build kernels on non-Linux hosts (cygwin & solaris) and testlpp really doesn't like to build on those. I have a separate patch to testlpp.c that fixes this, but it really makes no sense to build the tool to run on your cygwin host as it's meant to be run on Linux with the testlpp module loaded. Even this patch isn't really the right solution b/c you really want to cross-build the may be cross-building for another architecture from Linux you want cross-compile, not host compile but there's no really easy way to cross-compile a userland binary from the kernel build w/o some makefile uglyiness AFAICT. Is there some sort of -rt userland package this could move to instead of being in the kernel itself...?

[PATCH] Fix building kernel under Solaris
Fix varous build breakages that occur when building on a Solaris system
(SunOS 4.8 to be exact)
- No asm/types.h
- lpptest doesn't make sense on a Solaris host (this should really be
cross-built..)
- Need to define __s32 and __s16
- Need to define Elf32_Section and Elf64_Section
- Solaris does not provide strsep

[PATCH] Fix building kernel under Solaris
Fix varous build breakages that occur when building on a Solaris system
(SunOS 4.8 to be exact)
- No asm/types.h
- lpptest doesn't make sense on a Solaris host (this should really be
cross-built..)
- Need to define __s32 and __s16
- Need to define Elf32_Section and Elf64_Section
- Solaris does not provide strsep

[PATCH 2.6.13-rc7] Fix IXP4xx flash resource range
[Resend...forgot to send to lkml]
We are currently reserving one byte more than actually needed
by the flash device and overlapping into the next I/O expansion
bus window. This a) causes us to allocate an extra page of VM due
to ARM ioremap() alignment code and b) could cause problems
if another driver tries to request the next expansion bus window.

[PATCH] Allow for arch-specific IOREMAP_MAX_ORDER
Version 6 of the ARM architecture introduces the concept of 16MB pages
(supersections) and 36-bit (40-bit actually, but nobody uses this)
physical addresses. 36-bit addressed memory and I/O and ARMv6 can
only be mapped using supersections and the requirement on these is
that both virtual and physical addresses be 16MB aligned. In trying
to add support for ioremap() of 36-bit I/O, we run into the issue that
get_vm_area() allows for a maximum of 512K alignment via the
IOREMAP_MAX_ORDER constant. To work around this, we can:
- Allocate a larger VM area than needed (size + (1ul << IOREMAP_MAX_ORDER))
and then align the pointer ourselves, but this ends up with 512K of
wasted VM per ioremap().
- Provide a new __get_vm_area_aligned() API and make __get_vm_area() sit
on top of this. I did this and it works but I don't like the idea
adding another VM API just for this one case.
- My preferred solution which is to allow the architecture to override
the IOREMAP_MAX_ORDER constant with it's own version.

[PATCH 2.6.13-git] Fix IXP4xx CLOCK_TICK_RATE
[RMK is out for the week so sending this direct as it should go into 2.6.13] As pointed out in the following thread, the CLOCK_TICK_RATE setting for IXP4xx is incorrect b/c the HW ignores the lowest 2 bits of the LATCH value. http://lists.arm.linux.org.uk/pipermail/linux-arm-kernel/2005-August/030950.html Tnx to George Anziger and Egil Hjelmeland for finding the issue.

Intel's new XSC3 ARM core supports up to 36-bit addressing and they have several CPUs based on this that are already out or will be released in the next year. I can currently get around 64-bit resources by playing ugly tricks with the memory map and trapping ioremap() calls to a certain unused 32-bit physical range and fixing it up to 64-bit (like PPC440?? does) but that may not work on future CPUs that don't have holes in the memmap. > * How many 32-bit systems support a 64-bit PCI address space? This is a fairly common thing on some of the Intel XScale I/O and network processors. Some of the Intel CPUs provide a window in 32-bit CPU that translates to 64-bit PCI space. > * Should ioremap and variants start taking 64-bit physical addresses? If we are to use 64 bit resources, then yes. Or pfns... Do a google for my real opinion on this. I think ioremap() should take a device and resource describing the address of the resources in the address space of the device (the bus it is one). The whole resource and I/O subwystem currently assumes that physical and PCI bus address spaces are one and the same, but I have HW that breaks this assumption by allowing up to 2 GB of RAM and 3GB of PCI devices. Whenever this has been brought up though, Linus has shot it down. What we need is a real concept of per-bus address spaces and resources. But that is far more complicated change. > * Do we make this an arch option and wrap start and end in a typedef > similar to pte_t and provide accessor macros to ensure proper use? Probably the best thing to do b/c on really small systems that don't have 64-bit needs, we'll just be wasting memory with the extra data structure size. We need to scale down to PCI systems with just 8MB of RAM. ~Deepak -- Deepak Saxena - [EMAIL PROTECTED] - http://www.plexity.net Even a stopped clock gives the right time twice a day. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
