* Merge branch 'pstore-efi' of ↵Linus Torvalds2011-08-01
|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | git://git.kernel.org/pub/scm/linux/kernel/git/aegl/linux-2.6 * 'pstore-efi' of git://git.kernel.org/pub/scm/linux/kernel/git/aegl/linux-2.6: efivars: Introduce PSTORE_EFI_ATTRIBUTES efivars: Use string functions in pstore_write efivars: introduce utf16_strncmp efivars: String functions efi: Add support for using efivars as a pstore backend pstore: Allow the user to explicitly choose a backend pstore: Make "part" unsigned pstore: Add extra context for writes and erases pstore: Extend API for more flexibility in new backends
| * efivars: Introduce PSTORE_EFI_ATTRIBUTESMike Waychison2011-07-22
| | | | | | | | | | | | | | | | Consolidate the attributes listed for pstore operations in one place, PSTORE_EFI_ATTRIBUTES. Signed-off-by: Mike Waychison <mikew@google.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
| * efivars: Use string functions in pstore_writeMike Waychison2011-07-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of open-coding the string operations for comparing the prefix of the variable names, use the provided utf16_* string functions. This patch also changes the calls to efi.set_variable to efivars->ops->set_variable so that the right function gets called in the case of gsmi (which doesn't have a valid efi structure). As well, make sure that we only consider variables with the right vendor string. Signed-off-by: Mike Waychison <mikew@google.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
| * efivars: introduce utf16_strncmpMike Waychison2011-07-22
| | | | | | | | | | | | | | | | Introduce utf16_strncmp which is used in the next patch. Semantics should be the same as the strncmp C function. Signed-off-by: Mike Waychison <mikew@google.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
| * efivars: String functionsMike Waychison2011-07-22
| | | | | | | | | | | | | | | | | | | | | | | | | | Fix the string functions in the efivars driver to be called utf16_* instead of utf8_* as the encoding is utf16, not utf8. As well, rename utf16_strlen to utf16_strnlen as it takes a maxlength argument and the name should be consistent with the standard C function names. utf16_strlen is still provided for convenience in a subsequent patch.

| * efi: Add support for using efivars as a pstore backendMatthew Garrett2011-07-22
| | | | | | | | | | | | | | | | | | EFI provides an area of nonvolatile storage managed by the firmware. We can use this as a pstore backend to maintain copies of oopses, aiding diagnosis. Signed-off-by: Matthew Garrett <mjg@redhat.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
| * pstore: Allow the user to explicitly choose a backendMatthew Garrett2011-07-22
| | | | | | | | | | | | | | | | | | pstore only allows one backend to be registered at present, but the system may provide several. Add a parameter to allow the user to choose which backend will be used rather than just relying on load order.

| * pstore: Add extra context for writes and erasesMatthew Garrett2011-07-22
| | | | | | | | | | | | | | | | | | | | | | EFI only provides small amounts of individual storage, and conventionally puts metadata in the storage variable name. Rather than add a metadata header to the (already limited) variable storage, it's easier for us to modify pstore to pass all the information we need to construct a unique variable name to the appropriate functions.

| * pstore: Extend API for more flexibility in new backendsMatthew Garrett2011-07-22
| | | | | | | | | | | | | | | | | | Some pstore implementations may not have a static context, so extend the API to pass the pstore_info struct to all calls and allow for a context pointer. Signed-off-by: Matthew Garrett <mjg@redhat.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The first packet that gdb sends when the kernel is in kdb mode seems to change with every release of gdb. Instead of continuing to add many different gdb packets, change kdb to automatically look for any thing that looks like a gdb packet. Example 1 cold start test: echo g > /proc/sysrq-trigger $D#44+ Example 2 cold start test: echo g > /proc/sysrq-trigger $3#33 The second one should re-enter kdb's shell right away and is purely a test.

| | | | | | | | | | | | | | | | | | | | | | | | The DOING_KGDB2 was originally a state variable for one of the two ways to automatically transition from kdb to kgdb. Purge all these variables and just use one single state for the transition. Signed-off-by: Jason Wessel <jason.wessel@windriver.com>
| * | kdb,kgdb: Implement switch and pass buffer from kdb -> gdbJason Wessel2011-08-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When switching from kdb mode to kgdb mode packets were getting lost depending on the size of the fifo queue of the serial chip. When gdb initially connects if it is in kdb mode it should entirely send any character buffer over to the gdbstub when switching connections. Previously kdb was zero'ing out the character buffer and this could lead to gdb failing to connect at all, or a lengthy pause could occur on the initial connect.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, we take a sb->s_active reference and a cifsFileInfo reference when an oplock break workqueue job is queued. This is unnecessary and more complicated than it needs to be. Also as Al points out, deactivate_super has non-trivial locking implications so it's best to avoid that if we can. Instead, just cancel any pending oplock breaks for this filehandle synchronously in cifsFileInfo_put after taking it off the lists. That should ensure that this job doesn't outlive the structures it depends on.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The code that matches EA names in CIFSSMBQAllEAs is incorrect. It uses strncmp to do the comparison with the length limited to the name_len sent in the response. Problem: Suppose we're looking for an attribute named "foobar" and have an attribute before it in the EA list named "foo". The comparison will succeed since we're only looking at the first 3 characters. Fix this by also comparing the length of the provided ea_name with the name_len in the response. If they're not equal then it shouldn't match.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sniffing traffic on the wire shows that windows clients send a zeroed out signature field in a NEGOTIATE request, and send "BSRSPYL" in the signature field during SESSION_SETUP. Make the cifs client behave the same way. It doesn't seem to make much difference in any server that I've tested against, but it's probably best to follow windows behavior as closely as possible here.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | dss.c only saves 1 register (3 in OMAP3) so the extra overhead from need_ctx_restore & co. is probably bigger than the time spent saving and restoring those few registers every time. So remove the code from dss.c and restore context every time dss has been off. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
| * | | | OMAP: DSS2: Remove unused code from display.cTomi Valkeinen2011-07-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | oh_core variable is no longer used, so it and its initialization can be removed. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
| * | | | OMAP: DSS2: DISPC: remove finegrained clk enables/disablesTomi Valkeinen2011-07-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | dispc.c enables and disables clocks in almost every function to make sure the clocks are enabled when the function is called. This is rather unoptimal way to handle the problem. With pm_runtime other components have to call dispc_runtime_get() to enable dispc clocks before calling any other dispc functions. Thus the finegrained clk enables/disables can be removed. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
| * | | | OMAP: DSS2: Remove unused opt_clock_availableTomi Valkeinen2011-07-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | opt_clock_available() is no longer needed, so remove it. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
| * | | | OMAP: DSS2: Use PM runtime & HWMOD supportTomi Valkeinen2011-07-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use PM runtime and HWMOD support to handle enabling and disabling of DSS modules. Each DSS module will have get and put functions which can be used to enable and disable that module. The functions use pm_runtime and hwmod opt-clocks to enable the hardware.
