Add support for XLR and XLS processors in MIPS Oprofile code. These processors are multi-threaded and have two counters per core. Each counter can track either all the events in the core (global mode), or events in just one thread. We use the counters in the global mode, and use only the first thread in each core to handle the configuration etc. Signed-off-by: NMadhusudan Bhat <mbhat@netlogicmicro.com> Signed-off-by: NJayachandran C <jchandra@broadcom.com> Patchwork: http://patchwork.linux-mips.org/patch/4471Signed-off-by: NJohn Crispin <blogic@openwrt.org>

There are bcma based devices like the Linksys E2000 out there, which do have one ieee80211 core, but no PCIe core and they are using no prefixes for the sprom. In addition some values like boardtype are stored without a prefix for the main SoC chip also when they have an additional PCIe wifi chip with an own boardtype var on some devices. The Ethernet addresses are now also read out correctly without a prefix so calling bcm47xx_fill_sprom_ethernet is not needed any more.

The memory size is detected by finding a place where it repeats in memory. Currently we are just checking when the function prom_init is seen again, but it is better to check for a bigger part of the memory to decrease the chance of wrong results.

Commit 97ce2c88 (jump-label: initialize jump-label subsystem much earlier) caused MIPS to break, so this was resolved with commit 6650df3c (MIPS: Move cache setup to setup_arch().). Unfortunately, after this commit, the coherency kernel parameters, cca and coherentio, are no longer processed before their values are used. This patch fixes this problem by marking them as early_param, which results in them being processed before they are needed.

The cavium code assumed that all NOR on the boot bus was an 8-bit NOR part and hardcoded the bankwidth. The simple solution was to add the code that queries the configuration register for the width of the bus that has been hardware strapped to the Cavium.

In gfs2_trans_add_bh(), gfs2 was testing if a there was a bd attached to the buffer without having the gfs2_log_lock held. It was then assuming it would stay attached for the rest of the function. However, without either the log lock being held of the buffer locked, __gfs2_ail_flush() could detach bd at any time. This patch moves the locking before the test. If there isn't a bd already attached, gfs2 can safely allocate one and attach it before locking. There is no way that the newly allocated bd could be on the ail list, and thus no way for __gfs2_ail_flush() to detach it.

由 Benjamin Marzinski 提交于
file_accessed() was being called by gfs2_mmap() with a shared glock. If it needed to update the atime, it was crashing because it dirtied the inode in gfs2_dirty_inode() without holding an exclusive lock. gfs2_dirty_inode() checked if the caller was already holding a glock, but it didn't make sure that the glock was in the exclusive state. Now, instead of calling file_accessed() while holding the shared lock in gfs2_mmap(), file_accessed() is called after grabbing and releasing the glock to update the inode. If file_accessed() needs to update the atime, it will grab an exclusive lock in gfs2_dirty_inode(). gfs2_dirty_inode() now also checks to make sure that if the calling process has already locked the glock, it has an exclusive lock.

Currently implementation in gfs2 uses FITRIM arguments as it were in file system blocks units which is wrong. The FITRIM arguments (fstrim_range.start, fstrim_range.len and fstrim_range.minlen) are actually in bytes. Moreover, check for start argument beyond the end of file system, len argument being smaller than file system block and minlen argument being bigger than biggest resource group were missing. This commit converts the code to convert FITRIM argument to file system blocks and also adds appropriate checks mentioned above. All the problems were recognised by xfstests 251 and 260.
