2007-07-05[ARM] always allow dump_stack() to produce a backtraceRussell King
Don't make this dependent on CONFIG_DEBUG_KERNEL - if we hit a WARN_ON we need the stack trace to work out how we got to that point. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-07-04[ARM] Fix non-page aligned boot time mappingsRussell King
AT91SAM9260 stopped booting with the recent changes to MM initialisation - it was asking for a non-aligned virtual address which caused loops to be non-terminal. Fix this by rounding virtual addresses down, but remember to include the offset in the length, and round the length up to the following page. This means that asking for a mapping of 4K starting at 2K into a page maps two pages as one would expect. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2007-07-02[ARM] 4454/1: Use word accesses in Versatile PCI config readsAndrzej Zaborowski
ARM Versatile PCI config reads of one byte width have the lowest two bits of the address cleared and result in reading from a wrong place in the config space. This change is to use word size accesses like it is done for halfword reads. Byte reads are used for retrieving the IRQ number of a PCI device and the problem was not exposed until 2.6.20 because the value read was discarded in drivers/pci/setup-irq.c (recently fixed).

2007-07-01PM: introduce set_target method in pm_opsRafael J. Wysocki
Commit 52ade9b3b97fd3bea42842a056fe0786c28d0555 changed the suspend code ordering to execute pm_ops->prepare() after the device model per-device .suspend() calls in order to fix some ACPI-related issues. Unfortunately, it broke the at91 platform which assumed that pm_ops->prepare() would be called before suspending devices. at91 used pm_ops->prepare() to get notified of the target system sleep state, so that it could use this information while suspending devices. However, with the current suspend code ordering pm_ops->prepare() is called too late for this purpose. Thus, at91 needs an additional method in 'struct pm_ops' that will be used for notifying the platform of the target system sleep state. Moreover, in the future such a method will also be needed by ACPI. This patch adds the .set_target() method to 'struct pm_ops' and makes the suspend code call it, if implemented, before executing the device model per-device .suspend() calls. It also modifies the at91 code to use pm_ops->set_target() instead of pm_ops->prepare(). Signed-off-by: Rafael J.

2007-06-28Introduce fixed sys_sync_file_range2() syscall, implement on PowerPC and ARMDavid Woodhouse
Not all the world is an i386. Many architectures need 64-bit arguments to be aligned in suitable pairs of registers, and the original sys_sync_file_range(int, loff_t, loff_t, int) was therefore wasting an argument register for padding after the first integer. Since we don't normally have more than 6 arguments for system calls, that left no room for the final argument on some architectures. Fix this by introducing sys_sync_file_range2(int, int, loff_t, loff_t) which all fits nicely. In fact, ARM already had that, but called it sys_arm_sync_file_range. Move it to fs/sync.c and rename it, then implement the needed compatibility routine. And stop the missing syscall check from bitching about the absence of sys_sync_file_range() if we've implemented sys_sync_file_range2() instead. Tested on PPC32 and with 32-bit and 64-bit userspace on PPC64.

Fix a real section mismatch issue; the test code is thrown away after initialisation, but if we do not detect the VFP hardware, it is left hooked into the exception handler.

2007-05-21Detach sched.h from mm.hAlexey Dobriyan
First thing mm.h does is including sched.h solely for can_do_mlock() inline function which has "current" dereference inside. By dealing with can_do_mlock() mm.h can be detached from sched.h which is good. See below, why. This patch a) removes unconditional inclusion of sched.h from mm.h b) makes can_do_mlock() normal function in mm/mlock.c c) exports can_do_mlock() to not break compilation d) adds sched.h inclusions back to files that were getting it indirectly. e) adds less bloated headers to some files (asm/signal.h, jiffies.h) that were getting them indirectly Net result is: a) mm.h users would get less code to open, read, preprocess, parse, ... if they don't need sched.h b) sched.h stops being dependency for significant number of files: on x86_64 allmodconfig touching sched.h results in recompile of 4083 files, after patch it's only 3744 (-8.3%).

2007-05-17[ARM] ARMv6: add CPU_HAS_ASID configurationRussell King
Presently, we check for the minimum ARM architecture that we're building for to determine whether we need ASID support. This is wrong - if we're going to support a range of CPUs which include ARMv6 or higher, we need the ASID. Convert the checks to use a new configuration symbol, and arrange for ARMv6 and higher CPU entries to select it. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2007-05-17[ARM] gic: Fix gic cascade irq handlingRussell King
No need for the cascade irq function to have a "fastcall" annotation. Fix the range checking for valid IRQ numbers - comparing the value returned by the GIC with NR_IRQS is meaningless since we translate the GIC irq number to a Linux IRQ number afterwards. Check the GIC returned IRQ number is within limits first, then add the IRQ offset, and only then compare with NR_IRQS. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
