2011-07-15gma500: Add the Oaktrail HDMI supportAlan Cox
This differs enough from the Cedarview HDMI sufficiently to want to keep them separated. We need to sort out the power management for Oaktrail/Moorestown in order to plumb this lot into the register handling logic.

2011-07-15Separate handling of irq type flags variable from the irq_flags request_irq ↵Shyam Iyer
variable Commit 5f77898de17ff983ff0e2988b73a6bdf4b6f9f8b does not completely fix the problem of handling allocations with irqs disabled.. The below patch on top of it fixes the problem completely. Based on review by "Ivan Vecera" <ivecera@redhat.com>.. " Small note, the root of the problem was that non-atomic allocation was requested with IRQs disabled. Your patch description does not contain wwhy were the IRQs disabled. The function bnad_mbox_irq_alloc incorrectly uses 'flags' var for two different things, 1) to save current CPU flags and 2) for request_irq call. First the spin_lock_irqsave disables the IRQs and saves _all_ CPU flags (including one that enables/disables interrupts) to 'flags'. Then the 'flags' is overwritten by 0 or 0x80 (IRQF_SHARED). Finally the spin_unlock_irqrestore should restore saved flags, but these flags are now either 0x00 or 0x80. The interrupt bit value in flags register on x86 arch is 0x100. This means that the interrupt bit is zero (IRQs disabled) after spin_unlock_irqrestore so the request_irq function is called with disabled interrupts.

2011-07-15GFS2: Cache dir hash table in a contiguous bufferSteven Whitehouse
This patch adds a cache for the hash table to the directory code in order to help simplify the way in which the hash table is accessed. This is intended to be a first step towards introducing some performance improvements in the directory code. There are two follow ups that I'm hoping to see fairly shortly. One is to simplify the hash table reading code now that we always read the complete hash table, whether we want one entry or all of them. The other is to introduce readahead on the heads of the hash chains which are referred to from the table. The hash table is a maximum of 128k in size, so it is not worth trying to read it in small chunks. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>

2011-07-14x86: Kill handle_signal()->set_fs()Oleg Nesterov
handle_signal()->set_fs() has a nice comment which explains what set_fs() is, but it doesn't explain why it is needed and why it depends on CONFIG_X86_64. Afaics, the history of this confusion is: 1. I guess today nobody can explain why it was needed in arch/i386/kernel/signal.c, perhaps it was always wrong. This predates 2.4.0 kernel. 2. then it was copy-and-past'ed to the new x86_64 arch. 3. then it was removed from i386 (but not from x86_64) by b93b6ca3 "i386: remove unnecessary code". 4. then it was reintroduced under CONFIG_X86_64 when x86 unified i386 and x86_64, because the patch above didn't touch x86_64. Remove it. ->addr_limit should be correct. Even if it was possible that it is wrong, it is too late to fix it after setup_rt_frame(). Linus commented in: http://lkml.kernel.org/r/alpine.LFD.0.999.0707170902570.19166@woody.linux-foundation.org ... about the equivalent bit from i386: Heh. I think it's entirely historical. Please realize that the whole reason that function is called "set_fs()" is that it literally used to set the %fs segment register, not "->addr_limit". So I think the "set_fs(USER_DS)" is there _only_ to match the other regs->xds = __USER_DS; regs->xes = __USER_DS; regs->xss = __USER_DS; regs->xcs = __USER_CS; things, and never mattered. And now it matters even less, and has been copied to all other architectures where it is just totally insane.

2011-07-14x86, do_signal: Simplify the TS_RESTORE_SIGMASK logicOleg Nesterov
1. do_signal() looks at TS_RESTORE_SIGMASK and calculates the mask which should be stored in the signal frame, then it passes "oldset" to the callees, down to setup_rt_frame(). This is ugly, setup_rt_frame() can do this itself and nobody else needs this sigset_t. Move this code into setup_rt_frame. 2. do_signal() also clears TS_RESTORE_SIGMASK if handle_signal() succeeds. We can move this to setup_rt_frame() as well, this avoids the unnecessary checks and makes the logic more clear. 3. use set_current_blocked() instead of sigprocmask(SIG_SETMASK), sigprocmask() should be avoided.
