2005-08-26[PATCH] arm: fix IXP4xx flash resource rangeDeepak Saxena3-3/+3
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.

2005-08-17[ARM] 2850/1: Remove duplicate UART I/O mapping from s3c2410_iodescDimitry Andric1-2/+2
Patch from Dimitry Andric This patch removes the initial UART I/O mapping from s3c2410_iodesc, since the same mapping is already done in the function s3c24xx_init_io in the file arch/arm/mach-s3c2410/cpu.c, through the s3c_iodesc array. I'm not sure if duplicate mappings do any harm, but it's simply redundant. Also, in s3c2440.c the UART I/O mapping is NOT done. Additionally, I put a comma behind the last mapping, to ease copy/pasting stuff around, and make the style consistent with s3c2440.c and other files.

2005-08-10[ARM] Control v6 'global' bit via Linux PTE entriesRussell King2-5/+16
Unfortunately, we can't use the "user" bit in the page tables to control whether a page table entry is "global" or "asid" specific, since the vector page is mapped as "user" accessible but is not process specific. Therefore, give direct control of the ARMv6 "nG" (not global) bit to the mm layers. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2005-08-04[PATCH] pci and yenta: pcibios_bus_to_resourceDominik Brodowski1-0/+17
In yenta_socket, we default to using the resource setting of the CardBus bridge. However, this is a PCI-bus-centric view of resources and thus needs to be converted to generic resources first. Therefore, add a call to pcibios_bus_to_resource() call in between. This function is a mere wrapper on x86 and friends, however on some others it already exists, is added in this patch (alpha, arm, ppc, ppc64) or still needs to be provided (parisc -- where is its pcibios_resource_to_bus() ?).

Patch from Richard Purdie NWFPE used global variables which meant it wasn't safe for use with preemptive kernels. This patch removes them and communicates the information between functions in a preempt safe manner. Generation of some exceptions was broken and this has also been corrected.

2005-07-28[ARM SMP] Ensure secondary CPUs have a clean TLBRussell King1-0/+1
Since ARMv6 CPUs will not flush the TLB on context switches, it is possible that we may end up with some global TLB entries remaining present, eventually upsetting userspace.

machine_restart, machine_halt and machine_power_off are machine specific hooks deep into the reboot logic, that modules have no business messing with. Usually code should be calling kernel_restart, kernel_halt, kernel_power_off, or emergency_restart. So don't export machine_restart, machine_halt, and machine_power_off so we can catch buggy users.

Create a new top-level menu named "Networking" thus moving net related options and protocol selection way from the drivers menu and up on the top-level where they belong. To implement this all architectures has to source "net/Kconfig" before drivers/*/Kconfig in their Kconfig file. This change has been implemented for all architectures. Device drivers for ordinary NIC's are still to be found in the Device Drivers section, but Bluetooth, IrDA and ax25 are located with their corresponding menu entries under the new networking menu item.
