sh: Fix FDPIC binary loader

2013-01-21T19:44:58Z

commit 4a71997a3279a339e7336ea5d0cd27282e2dea44 upstream. Ensure that the aux table is properly initialized, even when optional features are missing. Without this, the FDPIC loader did not work.

sh: Fix cached/uncaced address calculation in 29bit mode

2011-11-21T22:31:15Z

commit dfd3b596fbbfa48b8e7966ef996d587157554b69 upstream. In the case of 29bit mode, CAC/UNCAC_ADDR does not return a right address. This revises this problem by using P1SEGADDR and P2SEGADDR in 29bit mode.

Fix node_start/end_pfn() definition for mm/page_cgroup.c

2011-06-27T21:13:09Z

commit 21a3c96 uses node_start/end_pfn(nid) for detection start/end of nodes. But, it's not defined in linux/mmzone.h but defined in /arch/???/include/mmzone.h which is included only under CONFIG_NEED_MULTIPLE_NODES=y. Then, we see mm/page_cgroup.c: In function 'page_cgroup_init': mm/page_cgroup.c:308: error: implicit declaration of function 'node_start_pfn' mm/page_cgroup.c:309: error: implicit declaration of function 'node_end_pfn' So, fixiing page_cgroup.c is an idea... But node_start_pfn()/node_end_pfn() is a very generic macro and should be implemented in the same manner for all archs. (m32r has different implementation...) This patch removes definitions of node_start/end_pfn() in each archs and defines a unified one in linux/mmzone.h. It's not under CONFIG_NEED_MULTIPLE_NODES, now. A result of macro expansion is here (mm/page_cgroup.c) for !NUMA start_pfn = ((&contig_page_data)->node_start_pfn); end_pfn = ({ pg_data_t *__pgdat = (&contig_page_data); __pgdat->node_start_pfn + __pgdat->node_spanned_pages;}); for NUMA (x86-64) start_pfn = ((node_data[nid])->node_start_pfn); end_pfn = ({ pg_data_t *__pgdat = (node_data[nid]); __pgdat->node_start_pfn + __pgdat->node_spanned_pages;}); Changelog: - fixed to avoid using "nid" twice in node_end_pfn() macro.

sh, exec: remove redundant set_fs(USER_DS)

2011-06-14T06:15:58Z

The address limit is already set in flush_old_exec() so those calls to set_fs(USER_DS) are redundant. Signed-off-by: Mathias Krause Signed-off-by: Paul Mundt

sh: Fix up xchg/cmpxchg corruption with gUSA RB.

2011-06-08T06:22:39Z

gUSA special cases r15 for part of its login/out sequence, meaning that any parameters need to be explicitly prohibited from accidentally being assigned that particular register, and the compiler ultimately needs to use a temporary instead. Certain configurations have begun generating code paths that do indeed get allocated r15, resulting in immediate corruption of the exchanged value. This was observed in (amongst others) exit_mm() code generation where the xchg_u32 call was immediately corrupting a structure address. As this is a general gUSA restriction, the rest of the users likewise need to be updated to ensure sensible constraints.

sh: Fix up asm-generic/ptrace.h fallout.

2011-05-31T05:39:49Z

There was an ordering issue with regards to instruction_pointer() being used in profile_pc() prior to the asm-generic/ptrace.h include, which subsequently provided the instruction_pointer() definition. In the interest of simplicity we simply open-code the regs->pc deref for the profile_pc() definition instead. The FP functions were also broken due to a lack of a common regs->fp, so provide a common GET_FP() that is safe for both architectures in order to fix up the frame pointer helpers too.

Merge branch 'setns'

* setns: ns: Wire up the setns system call Done as a merge to make it easier to fix up conflicts in arm due to addition of sendmmsg system call

ns: Wire up the setns system call

2011-05-28T17:48:39Z

32bit and 64bit on x86 are tested and working. The rest I have looked at closely and I can't find any problems. setns is an easy system call to wire up. It just takes two ints so I don't expect any weird architecture porting problems. While doing this I have noticed that we have some architectures that are very slow to get new system calls. cris seems to be the slowest where the last system calls wired up were preadv and pwritev. avr32 is weird in that recvmmsg was wired up but never declared in unistd.h. frv is behind with perf_event_open being the last syscall wired up. On h8300 the last system call wired up was epoll_wait. On m32r the last system call wired up was fallocate. mn10300 has recvmmsg as the last system call wired up. The rest seem to at least have syncfs wired up which was new in the 2.6.39. v2: Most of the architecture support added by Daniel Lezcano v3: ported to v2.6.36-rc4 by: Eric W. Biederman v4: Moved wiring up of the system call to another patch v5: ported to v2.6.39-rc6 v6: rebased onto parisc-next and net-next to avoid syscall conflicts. v7: ported to Linus's latest post 2.6.39 tree. > arch/blackfin/include/asm/unistd.h | 3 ++- > arch/blackfin/mach-common/entry.S | 1 + Acked-by: Mike Frysinger Oh - ia64 wiring looks good.
