2013-12-10x86/UV: Fix NULL pointer dereference in uv_flush_tlb_others() if the 'nobau' ↵cpw
boot option is used The SGI UV tlb shootdown code panics the system with a NULL pointer deference if 'nobau' is specified on the boot commandline. uv_flush_tlb_other() gets called for every flush, whether the BAU is disabled or not. It should not be keeping the s_enters statistic while the BAU is disabled. The panic occurs because during initialization init_per_cpu_tunables() does not set the bcp->statp pointer if 'nobau' was specified.

2013-12-10avr32: favr-32: clk_round_rate() can return a zero upon errorPaul Walmsley
Treat both negative and zero return values from clk_round_rate() as errors. This is needed since subsequent patches will convert clk_round_rate()'s return value to be an unsigned type, rather than a signed type, since some clock sources can generate rates higher than (2^31)-1 Hz. Eventually, when calling clk_round_rate(), only a return value of zero will be considered a error. All other values will be considered valid rates. The comparison against values less than 0 is kept to preserve the correct behavior in the meantime.

Commit dc77523c5da5513df1bbc74db2a522a94f4cec0e ensured that m.offset is only set for the MMAP memory mode by calling __setup_offsets only for that mode. However, __setup_offsets also initializes the length fields, and that should be done regardless of the memory mode. Because of that change the v4l2-ctl test application fails for the USERPTR mode. This fix creates a __setup_lengths function that sets the length, and __setup_offsets just sets the offset and no longer touches the length.

2013-12-09packet: fix send path when running with proto == 0Daniel Borkmann
Commit e40526cb20b5 introduced a cached dev pointer, that gets hooked into register_prot_hook(), __unregister_prot_hook() to update the device used for the send path. We need to fix this up, as otherwise this will not work with sockets created with protocol = 0, plus with sll_protocol = 0 passed via sockaddr_ll when doing the bind. So instead, assign the pointer directly. The compiler can inline these helper functions automagically. While at it, also assume the cached dev fast-path as likely(), and document this variant of socket creation as it seems it is not widely used (seems not even the author of TX_RING was aware of that in his reference example [1]).

2013-12-10powerpc: Fix up the kdump base cap to 128MMahesh Salgaonkar
The current logic sets the kdump base to min of 2G or ppc64_rma_size/2. On PowerNV kernel the first memory block 'memory@0' can be very large, equal to the DIMM size with ppc64_rma_size value capped to 1G. Hence on PowerNV, kdump base is set to 512M resulting kdump to fail while allocating paca array. This is because, paca need its memory from RMA region capped at 256M (see allocate_pacas()). This patch lowers the kdump base cap to 128M so that kdump kernel can successfully get memory below 256M for paca allocation.

2013-12-10powerpc: Fix PTE page address mismatch in pgtable ctor/dtorHong H. Pham
In pte_alloc_one(), pgtable_page_ctor() is passed an address that has not been converted by page_address() to the newly allocated PTE page. When the PTE is freed, __pte_free_tlb() calls pgtable_page_dtor() with an address to the PTE page that has been converted by page_address(). The mismatch in the PTE's page address causes pgtable_page_dtor() to access invalid memory, so resources for that PTE (such as the page lock) is not properly cleaned up. On PPC32, only SMP kernels are affected. On PPC64, only SMP kernels with 4K page size are affected. This bug was introduced by commit d614bb041209fd7cb5e4b35e11a7b2f6ee8f62b8 "powerpc: Move the pte free routines from common header". On a preempt-rt kernel, a spinlock is dynamically allocated for each PTE in pgtable_page_ctor(). When the PTE is freed, calling pgtable_page_dtor() with a mismatched page address causes a memory leak, as the pointer to the PTE's spinlock is bogus. On mainline, there isn't any immediately obvious symptoms, but the problem still exists here.

In checkin 5551a34e5aea x86-64, build: Always pass in -mno-sse we unconditionally added -mno-sse to the main build, to keep newer compilers from generating SSE instructions from autovectorization. However, this did not extend to the special environments (arch/x86/boot, arch/x86/boot/compressed, and arch/x86/realmode/rm). Add -mno-sse to the compiler command line for these environments, and add -mno-mmx to all the environments as well, as we don't want a compiler to generate MMX code either. This patch also removes a $(cc-option) call for -m32, since we have long since stopped supporting compilers too old for the -m32 option, and in fact hardcode it in other places in the Makefiles.

present commit dc75925d(OMAP: hwmod: Fix the missing braces) introduced missing braces, however, we just set return result if clk_get fail and we populate the error pointer in clk pointer and pass it along to clk_prepare. This is wrong. The intent seems to be retry remaining clocks if they are available and warn the ones we cant find clks for. With the current logic, we see the following crash: omap_hwmod: l3_main: cannot clk_get interface_clk emac_ick Unable to handle kernel NULL pointer dereference at virtual address 00000032 pgd = c0004000 [00000032] *pgd=00000000 Internal error: Oops: 5 [#1] SMP ARM Modules linked in: CPU: 0 PID: 1 Comm: swapper/0 Not tainted 3.13.0-rc1-00044-gcc9fd5a-dirty #19 task: ce0c3440 ti: ce0c4000 task.ti: ce0c4000 PC is at __clk_prepare+0x10/0x74 LR is at clk_prepare+0x14/0x24 <snip> [<c044d59c>] (__clk_prepare+0x10/0x74) from [<c044d9b0>] (clk_prepare+0x14/0x24) [<c044d9b0>] (clk_prepare+0x14/0x24) from [<c077d8c4>] (_init+0x24c/0x3bc) [<c077d8c4>] (_init+0x24c/0x3bc) from [<c0027328>] (omap_hwmod_for_each+0x34/0x5c) [<c0027328>] (omap_hwmod_for_each+0x34/0x5c) from [<c077dfa0>] (__omap_hwmod_setup_all+0x24/0x40) [<c077dfa0>] (__omap_hwmod_setup_all+0x24/0x40) from [<c0008928>] (do_one_initcall+0x38/0x168) [<c0008928>] (do_one_initcall+0x38/0x168) from [<c0771be8>] (kernel_init_freeable+0xfc/0x1cc) [<c0771be8>] (kernel_init_freeable+0xfc/0x1cc) from [<c0521064>] (kernel_init+0x8/0x110) [<c0521064>] (kernel_init+0x8/0x110) from [<c000e568>] (ret_from_fork+0x14/0x2c) Code: e92d4038 e2504000 01a05004 0a000005 (e5943034) So, just warn and continue instead of proceeding and crashing, with missing clock nodes/bad data, we will eventually fail, however we should now have enough information to identify the culprit.

2013-12-09ARM: OMAP3: hwmod data: Don't prevent RESET of USB Host moduleRoger Quadros
Unlike what the comment states, errata i660 does not state that we can't RESET the USB host module. Instead it states that RESET is the only way to recover from a deadlock situation. RESET ensures that the module is in a known good state irrespective of what bootloader does with the module, so it must be done at boot.

2013-12-09ARM: OMAP2+: hwmod: Fix SOFTRESET logicRoger Quadros
In _ocp_softreset(), after _set_softreset() + write_sysconfig(), the hwmod's sysc_cache will always contain SOFTRESET bit set so all further writes to sysconfig using this cache will initiate a repeated SOFTRESET e.g. enable_sysc(). This is true for OMAP3 like platforms that have RESET_DONE status in the SYSSTATUS register and so the the SOFTRESET bit in SYSCONFIG is not automatically cleared. It is not a problem for OMAP4 like platforms that indicate RESET completion by clearing the SOFTRESET bit in the SYSCONFIG register. This repeated SOFTRESET is undesired and was the root cause of USB host issues on OMAP3 platforms when hwmod was allowed to do the SOFTRESET for the USB Host module. To fix this we clear the SOFTRESET bit and update the sysconfig register + sysc_cache using write_sysconfig().
