2008-04-24[Blackfin] arch: Prevent potential Core Hang situationMichael Hennerich
If the new value written to the PLL_CTL or VR_CTL register is the same as the previous value, the PLL wake-up will occur immediately (PLL is already locked), but the core and system clock will be bypassed for the PLL_LOCKCNT duration. For this interval, code will execute at the CLKIN rate instead of at the expected CCLK rate. Software should guard against this condition by comparing the current value to the new value before writing the new value.

2008-04-24[Blackfin] arch: This allows XIP to work with FD-PIC.Bernd Schmidt
Previously, init failed to do anything meaningful; it turns out that the reason is that FD-PIC has a readonly data section which can be located in the XIP filesystem, and various address checks in the kernel reject such addresses for syscall arguments. Hence, init's execve ("/bin/sh", ...) failed with error code EFAULT. There's room for improvement here: in case people want to have filesystems on flash rather than in main memory, _access_ok should be modified to allow this. This bug fix is also dedicated to Michael Hennerich. Signed-off-by: Bernd Schmidt <bernds_cb1@t-online.de> Signed-off-by: Bryan Wu <cooloney@kernel.org>

where it actually gets used. relocate MAX_SWITCH_{D,I}_CPLBS from the header to the file where it actually gets used. this way when we change CONFIG_MEM_SIZE in our kconfig, we only rebuild one or two files rather than a whole bunch that implicitly include cplb.h. this will also remove the ability to clear the swapcount on the fly, but i really dont think that functionality is important. ultimate goal is for CONFIG_MEM_SIZE to go away and calculate this value on the fly based on what u-boot programmed for us.

2008-04-23[Blackfin] arch: fix bug - when using trace buffer with CONFIG_MPU enabled.Bernd Schmidt
There were a couple of problems with the way the trace buffer state is saved/restored in assembly. The DEBUG_HWTRACE_SAVE/RESTORE macros save a value to the stack, which is not immediately obvious; the CPLB exception code needed changes to load the correct value of the stack pointer. The other problem is that the SAVE/RESTORE macros weren't pushing and popping the value downwards on the stack, but rather moving it _upwards_, which is of course completely broken. We also need to make sure there's a matching DEBUG_HWTRACE_RESTORE in the error case of the CPLB handler.

2008-04-02kvm: provide kvm.h for all architecture: fixes headers_installChristian Borntraeger
Currently include/linux/kvm.h is not considered by make headers_install, because Kbuild cannot handle " unifdef-$(CONFIG_FOO) += foo.h. This problem was introduced by commit fb56dbb31c4738a3918db81fd24da732ce3b4ae6 Author: Avi Kivity <avi@qumranet.com> Date: Sun Dec 2 10:50:06 2007 +0200 KVM: Export include/linux/kvm.h only if $ARCH actually supports KVM Currently, make headers_check barfs due to <asm/kvm.h>, which <linux/kvm.h> includes, not existing. Rather than add a zillion <asm/kvm.h>s, export kvm. only if the arch actually supports it. Signed-off-by: Avi Kivity <avi@qumranet.com> which makes this an 2.6.25 regression. One way of solving the issue is to enhance Kbuild, but Avi and David conviced me, that changing headers_install is not the way to go. This patch changes the definition for linux/kvm.h to unifdef-y. If  unifdef-y is used for linux/kvm.h "make headers_check" will fail on all architectures without asm/kvm.h. Therefore, this patch also provides asm/kvm.h on all architectures.
