Currently at the start of a journal commit we loop through all of the buffers on the committing transaction and clear the b_modified flag (the flag that is set when a transaction modifies the buffer) under the j_list_lock. The problem is that everywhere else this flag is modified only under the jbd2 lock buffer flag, so it will race with a running transaction who could potentially set it, and have it unset by the committing transaction. This is also a big waste, you can have several thousands of buffers that you are clearing the modified flag on when you may not need to. This patch removes this code and instead clears the b_modified flag upon entering do_get_write_access/journal_get_create_access, so if that transaction does indeed use the buffer then it will be accounted for properly, and if it does not then we know we didn't use it. That will be important for the next patch in this series. Tested thoroughly by myself using postmark/iozone/bonnie++. Cc: <linux-ext4@vger.kernel.org> Cc: Jan Kara <jack@ucw.cz> Signed-off-by:

Legacy HP ia64 platforms currently cannot provide /proc/cpuinfo/physical_id due to legacy SAL/PAL implementations. However, that physical topology information can be obtained via ACPI. Provide an interface that gives ACPI one last chance to provide physical_id for these legacy platforms. This logic only comes into play iff: - ACPI actually provides slot information for the CPU - we lack a valid socket_id Otherwise, we don't do anything. Since x86 uses the ACPI processor driver as well, we provide a nop stub function for arch_fix_phys_package_id() in asm-x86/topology.h Signed-off-by:

Tuner setup were happening during i2c attach callback. This means that it would happen on two conditions: 1) if tuner module weren't load, it will happen at request_module("tuner"); 2) if tuner is not compiled as a module, or it is already loaded (for example, on setups with more than one tuner), it will happen when saa7134 registers I2C bus. Due to that, if tuner were loaded, tuner setup will happen _before_ reading the proper values at tuner eeprom. Since set_addr refuses to change for a tuner that were previously defined (except if the tuner_addr is set), this were making eeprom tuner detection useless. This patch removes tuner type setup from saa7134-i2c, moving it to the proper place, after taking eeprom into account. Reviewed-by:Hermann Pitton <hermann-pitton@arcor.de> Signed-off-by:
