The xtime value may become incorrect when the update_wall_time(ticks) function is called with "ticks" > 1. In such a case, the xtime variable is updated multiple times inside the loop but it is normalized only once outside of the loop.

This patch allows ReiserFS to handle I/O errors in the journal (or journal flush) where it would have previously panicked. The new behavior is to mark the filesystem read-only, disallow new transactions to be started, and to allow existing transactions to complete (though not to commit). The resultant filesystem can be safely umounted, and checked via normal mechanisms. As it is a journaling filesystem, the filesystem itself will be in a similar state to the power being cut to the machine, once umounted. Signed-off-by:

This patch cleans up fs/reiserfs/journal.c such that repeated uses of SB_JOURNAL(p_s_sb) are removed in favor of a local journal variable. The compiler won't care, and it makes the code much easier to read. Signed-off-by:

This patch cleans up ReiserFS's use of buffer head flags. All direct access of BH_* are made into macro calls, and all reiserfs-specific BH_* macro implementations have been removed and replaced with the BUFFER_FNS implementations found in linux/buffer_head.h Signed-off-by:

Here is a patch to support the M32R SIO (serial IO) driver. This driver supports the M32R serial ports. - Supports two types M32R serial interfaces; M32R_SIO and M32R_PLDSIO. - With SMP safeness. Currently the M32R_PLDSIO serial interface, which is implemented on a PLD on the M3T-M32700UT evaluation board, has slightly different specification from the integrated peripheral SIO (M32R_SIO). Now we can select them by CONFIG_ option. It is a serial-core based driver, based on drivers/serial/8250.c. Any comments or suggestions will be appreciated. Signed-off-by:

As part of the workaround for the "Interrupt message re-ordering across hub interface" errata (page #16 in http://developer.intel.com/design/chipsets/specupdt/30288402.pdf), BIOS may enable hardware IRQ balancing for E7520/E7320/E7525(revision ID 0x9 and below) based platforms. Add pci quirks to disable SW irqbalance/affinity on those platforms. Move balanced_irq_init() to late_initcall so that kirqd will be started after pci quirks. Signed-off-by:

- valid_stack_ptr() erroneously assumes that stack always lives in task_struct->thread_info. - the main loop in show_trace() does not recalc ebp after stack switching. With CONFIG_FRAME_POINTER every call to print_context_stack() will produce the same output. With this patch, show_trace() does not use task argument in the main loop. Instead, it converts stack to thread_info* context, and passes it to print_context_stack() and (implicitly) to valid_stack_ptr(). valid_stack_ptr() now does bounds checking against proper context.
