The radix tree functions __lookup and __lookup_tag uses (1 << shift) in their index calculations. On 64 bit systems the shift can be bigger than 32. The shift of an integer by more than 32 bits evaluates to zero which causes the lookup to fail. Signed-off-by:

This is ES7000 sub arch update. The tiny patch below fixes a bug that results in boot problem on all ES7000 partitions with numbers higher than 0. Currently, target_cpus() returns incorrect cpumask value since it indexes bits by the logical APIC ID, not by CPU number. The patch affects only ES7000 sub arch. It was tested extensively on the system with multiple partitions. Signed-off-by:

- Update display->vrows when fbset changes certain fields in var (such as color depth) but without changing the display resolution. This might produce concommitant changes in other fields such as and especially var->yres_virtual. - Clear the FBINFO_MISC_MODECHANGEUSER flag _before_ issuing a notifier_call_chain(). Clearing it after the notifier_call_chain() will cause fbcon to go into an infinite loop. - Sanitized failure path of set_con2fb_map(). Signed-off-by:

As we've discussed in another thread, below is a diff that will do a set_par() as late as possible when there is KD_TEXT<->KD_GRAPHICS switch. The set_par() will be forced in fbcon_resize() instead. Not sure if this has repercussions with the other drivers, but this patch fixed the X nv driver hanging when switching to the console. (I believe the crash is actually caused by an early set_par() -- while in fbcon_blank. Removing the set_par in fbcon_blank fixed the hang but caused cursor sprite and display corruption).

One way to help that would be to use buffer[] also in place of namebuf[], but that would be little tricky as the format string should be before the symbol name ... Signed-off-by:

As required by the standard, this patch adds to POSIX ABSOLUTE timers the functionality of adjusting the timer when the clock is set so that it still expires at the specified time (provided that time has not passed, in which case the timer expires immeadiatly). The standard is, IMNSOHO, a bit vague on just how repeating timers are to be handled so I made some choices: 1) If an absolute timer is to expire every N intervals, we assume that the expiries should happen at those specified times after clock setting. I.e. we adjust the repeat timer as well as the initial timer. (The other option would be to treat the repeating timers as relative and not to adjust them.) 2) If a clock set moves the the clock prior to the initial expiry time AND that time has already passed and been signaled, the current repeat timer is adjusted, i.e. we DO NOT go back to the initial time and repeat that. (The other option is to treat this case as a new request with the initial timer parameters (which by this time we have lost).) 3) If time is advanced such that it appears that several expiries have been missed, the overrun count will reflect the misses. (The other option is to not reflect this in the overrun.) At the same time, nothing is done to acknowledge, to the user, that we are repeating expiries when the clock is retarded.

Attached is the latest version of Adrian Cox's OCP patch for MPC107/8240/8245. This unifies some openpic setup code, and ensures that the OCP devices are only added to the bus on chip variants which have them. All interested parties seem happy, and this patch is necessary to provide a unified I2C driver for 85xx and 107/824x. Signed-off-by:

Recently I changed the return value of rtas_call() from an unsigned long to an int. That patch missed a few places where we declare a variable to store the result from rtas_call(). This new patch changes those places to use an int variable instead of a long or unsigned long variable. Linas Vepstas pointed this out. Signed-off-by:

This patch from Linas Vepstas (rediffed by me) fixes the confusing argument aliasing of the log_rtas_error() subroutine. This patch makes no functional changes, it just cleans up some strange usage. The rtas_args used to communicate with firmware are always taken from the paca struct, so as to keep the args at a fixed, low-memory location. But the log_rtas_error() routine also took an rtas_args pointer, which it assumed was aliased to the paca struct. This aliasing is both un-neccessary, and confusing; this patch eliminates this confusion. Signed-off-by:

Cleanup the PPC64 PACA structure. It was previously a big mess of unecessary fields, overengineered cache layout and uninformative comments. This is essentially a rewrite of include/asm-pp64/paca.h with associated changes elsewhere. The patch: - Removes unused PACA fields - Removes uneeded #includes - Uses gcc attributes instead of explicit padding to get the desired cacheline layout, also rethinks the layout and comments accordingly. - Better comments where asm or firmware dependencies apply non-obvious layout constraints. - Splits up the pointless STAB structure, letting us move its elements independently. - Uses offsetof instead of hardcoded offset in spinlocks. - Eradicates xStudlyCaps identifiers - Replaces PACA guard page with an explicitly defined emergency stack (removing more than NR_CPUS pages from the initialized data segment).

This patch removes the RTAS arguments structure on ppc64 from the PACA. The args have to be in the RMO, but since we have a global spinlock for RTAS anyway, there's no reason to have a separate copy of the args per-CPU. This patch replaces the PACA field with a single instance in the global rtas structure. The one exception is for the rtas_stop_self() call, which can't take the lock, because it never returns. But it has a fixed set of arguments, so we can use another global instance which is initialized at boot. This lets us remove rtas.h from paca.h, which substantially reduces overall #include hairiness (because paca.h is now, as it wants to be, a nice low-level structure-defining header which relies on very little and can safely be included almost anywhere). Although it does add some noise to the patch, because a bunch of places relied on the indirect inclusion of rtas.h, or even more indirect inclusions (see the hunks applying to eeh.h and current.h!).

Current 2.6.7 tree acts as if it is alway under memory pressure because a recent change did a s/tcp_memory_pressure/tcp_prot.memory_pressure/. The problem is tcp_prot.memory_pressure is a pointer, so it is always non-zero! Rather than using *tcp_prot.memory_pressure, just go back to looking at tcp_memory_pressure. Signed-off-by:

'strace' shows a problem with a missing release_task for self-reaping clones that have been traced. We need to defer releasing them until the tracer is done with them, but if the tracer dies, we need to handle that case gracefully too. We do that by having 'forget_original_parent()' generate a list of tasks to release when this case happens. Patch based on discussions on linux-kernel, and suggestions from Roland McGrath <roland@redhat.com>.

This fixes a corner-case NX bug: the x86 SMP kernel doesnt boot on SMP Opterons if NX is enabled [and mem=nopentium is specified], due to kernel-space NX protection preventing the SMP trampoline from being executable. Since the SMP trampoline is a rare case of 'dynamic code' executed by the kernel (it has to be below 640K so it cannot be part of the kernel text itself), i've added the necessary infrastructure to enable/disable executability of specific kernel pages. We cannot simply disable NX via the MSR because we've got the NX bits in the kernel pagetables, which are set up before we do the SMP bootup. The NX bit in the pagetables is undefined if EFER.NXE is 0, so we cannot count on NX-capable CPUs not faulting when they encounter them. I've tested the x86 kernel on a non-NX SMP x86 box and on an NX UP box, on which i've also tested a simulated SMP trampoline, it all works fine. - add infrastructure to enable/disable executability of kernel pages - make the SMP trampoline page executable.
