* MIPS: O32 compat/N32: Fix to use compat syscall wrappers for AIO syscalls.Michel Thebeau2010-10-192-6/+6

| | | | | | | | IOC3 is also being used on SGI MIPS systems but this particular driver is only being used on IA64 systems so linux-mips made no sense as a list. Pat also thinks linux-serial@vger.kernel.org is the better list. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

* MIPS: Repair Kbuild make clean breakage.David Daney2010-10-192-1/+5
| | | | | | | | | | | | | | | | When running make clean, Kbuild doesn't process the .config file, so nothing generates a platform-y variable. We can get it to descend into the platform directories by setting $(obj-). The dec Platform file was unconditionally setting platform-, obliterating its previous contents and preventing some directories from being cleaned. This is change to an append operation '+=' to allow cavium-octeon to be cleaned.

| * cifs: prevent infinite recursion in cifs_reconnect_tconJeff Layton2010-10-011-16/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | cifs_reconnect_tcon is called from smb_init. After a successful reconnect, cifs_reconnect_tcon will call reset_cifs_unix_caps. That function will, in turn call CIFSSMBQFSUnixInfo and CIFSSMBSetFSUnixInfo. Those functions also call smb_init. It's possible for the session and tcon reconnect to succeed, and then for another cifs_reconnect to occur before CIFSSMBQFSUnixInfo or CIFSSMBSetFSUnixInfo to be called. That'll cause those functions to call smb_init and cifs_reconnect_tcon again, ad infinitum... Break the infinite recursion by having those functions use a new smb_init variant that doesn't attempt to perform a reconnect.

It deals with these by attempting to translate them through the current set of page tables. This is fine for userspace memory and vmalloc()'d areas as they are governed by page tables. However, since the regions above 0x80000000 aren't translated through the page tables by the MMU, the kernel doesn't bother to set up page tables for them (see paging_init()). This means flush_icache_range() as it stands cannot be used to flush regions of the VM area between 0x80000000 and 0x9fffffff where the kernel resides if the data cache is operating in WriteBack mode. To fix this, make flush_icache_range() first check for addresses in the upper half of VM space and deal with them appropriately, before dealing with any range in the page table mapped area. Ordinarily, this is not a problem, but it has the capacity to make kprobes and kgdb malfunction. It should not affect gdbstub, signal frame setup or module loading as gdb has its own flush functions, and the others take place in the page table mapped area only.

Fix this my just making handle count an atomic on the object, and have it increase the normal object kref. Now i915/radeon/nouveau drivers can drop the normal reference on userspace object creation, and have the handle hold it. This patch fixes a memory leak or corruption on unload, because the driver had no way of knowing if a handle had been actually added for this object, and the fbcon object needed to know this to clean itself up properly.

This bit gets set by hardware to indicate that the system woke up due to a PCI Express wakeup event, so clear it during acpi_hw_clear_acpi_status() calls to enable subsequent resumes to work.

However, it turned out that this change broke suspend-resume on a few systems, so commit 72ad5d77fb981963edae15eee8196c80238f5ed0 (ACPI / Sleep: Allow the NVS saving to be skipped during suspend to RAM) introduced the acpi_sleep=nonvs command line switch to allow their users to work around this issue. To keep track of the systems that require this workaround and to make the life of their users slightly easier blacklist them in acpisleep_dmi_table[]. https://bugzilla.kernel.org/show_bug.cgi?id=16396 Signed-off-by: Rafael J.
