2005-08-29[PATCH] convert signal handling of NODEFER to act like other Unix boxes.Steven Rostedt
It has been reported that the way Linux handles NODEFER for signals is not consistent with the way other Unix boxes handle it. I've written a program to test the behavior of how this flag affects signals and had several reports from people who ran this on various Unix boxes, confirming that Linux seems to be unique on the way this is handled. The way NODEFER affects signals on other Unix boxes is as follows: 1) If NODEFER is set, other signals in sa_mask are still blocked. 2) If NODEFER is set and the signal is in sa_mask, then the signal is still blocked. (Note: this is the behavior of all tested but Linux _and_ NetBSD 2.0 *). The way NODEFER affects signals on Linux: 1) If NODEFER is set, other signals are _not_ blocked regardless of sa_mask (Even NetBSD doesn't do this). 2) If NODEFER is set and the signal is in sa_mask, then the signal being handled is not blocked. The patch converts signal handling in all current Linux architectures to the way most Unix boxes work. Unix boxes that were tested: DU4, AIX 5.2, Irix 6.5, NetBSD 2.0, SFU 3.5 on WinXP, AIX 5.3, Mac OSX, and of course Linux 2.6.13-rcX. * NetBSD was the only other Unix to behave like Linux on point #2. The main concern was brought up by point #1 which even NetBSD isn't like Linux. So with this patch, we leave NetBSD as the lonely one that behaves differently here with #2.

2005-08-26[PATCH] arm: fix IXP4xx flash resource rangeDeepak Saxena
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 Andric
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 King
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.

2005-08-04[PATCH] pci and yenta: pcibios_bus_to_resourceDominik Brodowski
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() ?).

2005-07-28[ARM SMP] Ensure secondary CPUs have a clean TLBRussell King
