2011-04-15Kconfig: improve KALLSYMS_ALL documentationArtem Bityutskiy1-6/+12
Dumb users like myself are not able to grasp from the existing KALLSYMS_ALL documentation that this option is not what they need. Improve the help message and make it clearer that KALLSYMS is enough in the majority of use cases, and KALLSYMS_ALL should really be used very rarely.

2011-03-29amd64_edac: Fix potential memleakBorislav Petkov1-1/+1
We check the pointers together but at least one of them could be invalid due to failed allocation. Since we cannot continue if either of the two allocations has failed, exit early by freeing them both.

2011-03-29fs: don't use igrab() while holding i_lockDave Chinner3-4/+5
Fix the incorrect use of igrab() inside the i_lock in NFS and Ceph‥ If we are already holding the i_lock, we have a reference to the inode so we can safely use ihold() to gain an extra reference. This avoids hangs due to lock recursion on the i_lock now that the inode_lock is gone and igrab() uses the i_lock itself.

Fix section mismatch warnings: set_phys_range_identity() is called by __init xen_set_identity(), so also mark set_phys_range_identity() as __init. then: __early_alloc_p2m() is called set_phys_range_identity(), so also mark __early_alloc_p2m() as __init.

2011-03-29FRV: Missing node arg in alloc_thread_info_node() macroDavid Howells1-1/+1
There are two alloc_thread_info_node() macros defined (one for debugging and one for normal). The commit that changed them most recently: commit b6a84016bd2598e35ead635147fa53619982648d Author: Eric Dumazet <eric.dumazet@gmail.com> Date: Tue Mar 22 16:30:42 2011 -0700 Subject: mm: NUMA aware alloc_thread_info_node() didn't add the node argument into the macro argument list for the normal macro. This results in the following error: kernel/fork.c:267:39: error: macro "alloc_thread_info_node" passed 2 arguments, but takes just 1 kernel/fork.c: In function 'dup_task_struct': kernel/fork.c:267: error: 'alloc_thread_info_node' undeclared (first use in this function) kernel/fork.c:267: error: (Each undeclared identifier is reported only once kernel/fork.c:267: error: for each function it appears in.)

2011-03-29sparc: Use the new genirq functionalityThomas Gleixner2-24/+9
Make use of the new features in genirq: 1) Set the chip flag IRCHIP_EOI_IF_HANDLED, which ensures in the core code that irq_eoi() is only called when the interrupt was handled. That removes the extra status check in the callback. 2) Use the preflow handler, which is called from the fasteoi core code before the device handler. That avoids another status check and the open coded handler redirection. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Cc: sparclinux@vger.kernel.org
