Following the recent implementation of TIF_RESTORE_SIGMASK in arch/mips/kernel/signal.c, 64-bit kernels with 32-bit user-land compatibility oops when starting init. signal32.c needs to be converted to use TIF_RESTORE_SIGMASK too. Signed-off-by:

It seems current get_user() incorrectly sign-extend an unsigned int value on 64bit kernel. I think this is because '(__typeof__(val))' cast in final assignment. I suppose the cast should be '(__typeof__(*(addr))'. Signed-off-by:

In daemonize() a new thread gets cleaned up and 'merged' with init_task. The current fs_struct is handled there, but not the current namespace. This adds the namespace part. [ Eric Biederman pointed out the namespace wrappers, and also notes that we can't ever count on using our parents namespace because we already have called exit_fs(), which is the only way to the namespace from a process. ] Signed-off-by:

This patch updates and fixes sys_tas() routine for m32r. In the previous implementation, a lockup rarely caused at sys_tas() routine in SMP environment. > > The problem is that touching *addr will generate an oops if that page isn't > > paged in.

I rewrote sys_tas() routine by using "lock -> unlock" instructions, and utilizing the m32r's interrupt handling characteristics; the m32r processor can accept interrupts only at the 32-bit instruction boundary. So, the "unlock" instruction can be executed continuously after the "lock" instruction execution without any interruptions. In addition, to solve such a page_fault problem, I use a fixup code like get_user(). And, as for the kernel lockup problem, we found that a calling do_page_fault() routine with disabling interrupts might cause a lockup at flush_tlb_others(), because we checked a completion of IPI handler's operations in a spin-locked critical section. Therefore, by using "lock -> unlock" code, we can implement the sys_tas() rouitine without disabling interrupts explicitly, then no lockups would happen at flush_tlb_others(), I hope. Compile check and some working test in SMP environment have done. Signed-off-by:

This patch fixes a bug of include/asm-m32r/system.h:__cmpxchg_u32(). static __inline__ unsigned long __cmpxchg_u32(volatile unsigned int *p, unsigned int old, unsigned int new); In __cmpxchg_u32(), the "old" value must not be changed to the previous "*p" value. But the former code modifies the previous "*p" value. A deadlock at _atomic_dec_and_lock sometimes happened due to this bug. Signed-off-by:

Using FCP devices with V=V support, the input queue stalled when CCQ 97 had been returned in qdio_do_eqbs. When this happen we have to reissue the eqbs instruction. Another bug was when V=V was enabled we checked if hardware has SIGA-sync support. If not we returned with 0 from tiqdio_is_inbound_q_done. Thus qdio lost initiative on FCP devices and input queue stalled. Running devices in V=V there is no SIGA-sync support but nevertheless we have to process tiqdio_is_inbound_q_done either.

Make resume from suspend-to-ram possible for Samsung P35 laptops. The radeon mobility 9700 chip on Samsung P35 laptops locks up everything on resume from suspend-to-ram if it is not reinitialized. VGA compatible controller: ATI Technologies Inc RV350 [Mobility Radeon 9600 M10] Class 0300: 1002:4e50 Subsystem: 144d:c00c Unfortunately, the DMI strings are mostly identical for all Samsung laptops. So we match the PCI ID and subsystem ID of the graphics card which is unique for each Samsung laptop model. Signed-off-by:Carl-Daniel Hailfinger <c-d.hailfinger.devel.2006@gmx.net> Signed-off-by:

Some recent PowerBook models tend to lose the ethernet PHY on suspend/resume. It -seems- that they use a combo ethernet-firewire PHY chip and the firewire PHY seems to die the same way when that happens. Not trying to toggle the firewire cable power appears to fix it. So this patch disables changes to the firewire cable power control GPIO on those models. Signed-off-by:

Currently, acpi video options can only be set on kernel command line. That's little inflexible; I'd like userland s2ram application that just works, and modifying kernel command line according to whitelist is not fun. It is better to just allow s2ram application to set video options just before suspend (according to the whitelist). This implements sysctl to allow setting suspend video options without reboot. (akpm: Documentation updates for this new sysctl are pending..) Signed-off-by:

I found an issue in cfi_cmdset0001.c. It is related to cache region invalidation in the buffered write procedure. The code performs cache invalidation from "cmd_addr" to "cmd_adr + len" in do_write_buffer() while we modify region from "adr" to "adr+len". This issue affects writes + reads of data by small chunks.

I'm seeing a kernel panic on an ES7000-600 when booting in virtual wire mode. The panic happens because smp_read_mpc() is passed a physical address, and it should be virtual. I tested the attached patch on the ES7000-600 and on a 2 cpu Dell box, and saw no problems on either. Signed-off-by:
