| * | | parisc: use spin_lock_irqsave/spin_unlock_irqrestore for PTE updatesJohn David Anglin2013-04-252-26/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | User applications running on SMP kernels have long suffered from instability and random segmentation faults. This patch improves the situation although there is more work to be done. One of the problems is the various routines in pgtable.h that update page table entries use different locking mechanisms, or no lock at all (set_pte_at). This change modifies the routines to all use the same lock pa_dbit_lock. This lock is used for dirty bit updates in the interruption code. The patch also purges the TLB entries associated with the PTE to ensure that inconsistent values are not used after the page table entry is updated. The UP and SMP code are now identical. The change also includes a minor update to the purge_tlb_entries function in cache.c to improve its efficiency.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | CONFIG_MLONGCALLS was introduced in commit ec758f98328da3eb933a25dc7a2eed01ef44d849 to overcome linker issues when linking huge linux kernels, e.g. with many modules linked in. But in the kernel module loader there is no support yet for the new relocation types, which is why modules built with -mlong-calls can't be loaded. Furthermore, for modules long calls are not really necessary, since we already use stub sections which resolve long distance calls. So, let's just disable this compiler option when compiling kernel modules. Signed-off-by: Helge Deller <deller@gmx.de>

If the type of __val is a pointer, the marshalling code casts it to the wider integer type of u64, resulting in the following compiler warnings: kernel/signal.c: In function 'copy_siginfo_to_user': kernel/signal.c:2752:11: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] kernel/signal.c:2752:11: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] [...] This patch fixes the warnings by removing the marshalling code and using the correct output modifiers in the __put_{user,kernel}_asm64 macros so that GCC will allocate the right registers without the need to extract the two words explicitly.

A distinction between desktop and server parts is introduced because bits 24-30 are only available on the server parts.

And now have to append crashkernel_low=Y in first kernel to make kdump work. We have now modified crashkernel=X to allocate memory beyong 4G (if available) and do not allocate low range for crashkernel if the user does not specify that with crashkernel_low=Y. This causes regression if iommu is not enabled. Without iommu, swiotlb needs to be setup in first 4G and there is no low memory available to second kernel. Set crashkernel_low automatically if the user does not specify that.

Space that hasn't yet been garbage collected isn't available for use and so isn't counted in the remaining_space field returned by QueryVariableInfo(). Combined with commit 68d9298 this can cause problems. Some implementations don't garbage collect until the remaining space is smaller than the maximum variable size, and as a result check_var_size() will always fail once more than 50% of the variable store has been used even if most of that space is marked as available for garbage collection. The user is unable to create new variables, and deleting variables doesn't increase the remaining space. The problem that 68d9298 was attempting to avoid was one where certain platforms fail if the actively used space is greater than 50% of the available storage space. We should be able to calculate that by simply summing the size of each available variable and subtracting that from the total storage space. With luck this will fix the problem described in https://bugzilla.kernel.org/show_bug.cgi?id=55471 without permitting damage to occur to the machines 68d9298 was attempting to fix.

This makes it awkward for us to figure out how much space they use at runtime. In theory we could figure this out by simply comparing the results from QueryVariableInfo() to the space used by all of our variables, but that fails if the platform doesn't garbage collect on every boot. Thankfully, calling QueryVariableInfo() while still inside boot services gives a more reliable answer. This patch passes that information from the EFI boot stub up to the efi platform code.

It seems that my compiler isn't inlining cyc_to_sched_clock() though, so I'm hitting a recursion bug when I enable the function graph tracer, causing my system to crash. Marking these functions notrace fixes it. Technically cyc_to_ns() doesn't need the notrace because it's already marked inline, but let's just add it so that if we ever remove inline from that function it doesn't blow up.

Thus the L2 needs to be invalidated after both L1 caches are disabled. On kexec before the starting the code for relocation the kernel, the L1 caches are disabled in cpu_froc_fin (cpu_v7_proc_fin for Feroceon), but after L2 cache is never invalidated, because inv_all is not set in cache-feroceon-l2.c. So kernel relocation and decompression may has (and usually has) errors. Setting the function enables L2 invalidation and fixes the issue.

| | * | | | | | ARM: mm: remove broken condition check for v4 flushingWill Deacon2013-03-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's no point having a conditional cache flush if we don't know the state of the condition beforehand. This patch makes the cacheflush in v4_flush_user_cache_range unconditional. signed-off-by: will deacon <will.deacon@arm.com>
| | * | | | | | ARM: mm: fix numerous hideous errors in proc-arm740.SWill Deacon2013-03-261-12/+16

I was >this< close to ripping it out, when a 740t core-tile materialised in the office, so I've had a crack at fixing things up: - Fix the ram/flash area calculations so that we actually set the condition flags before testing them... - Fix the proc_info structure so that __cpu_io_mmu_flags are defined as 0, placing the __cpu_flush pointer at the correct offset - Re-number the registers used during __arm740_setup so that we don't clobber the machine ID et al - Advertise Thumb support via the hwcaps, since 740T is the only 740 implementation.

Tested with 740T core-tile on Integrator/AP baseboard. Acked-by: Hyok S. Choi <hyok.choi@samsung.com> Acked-by: Greg Ungerer <gerg@uclinux.org> Signed-off-by: Will Deacon <will.deacon@arm.com>
