| Subject: parisc: remove _STK_LIM_MAX override |
| |
| From: John David Anglin <dave.anglin@bell.net> |
| |
| commit e0d8898d76a785453bfaf6cd08b830a7d5189f78 upstream. |
| |
| There are only a couple of architectures that override _STK_LIM_MAX to |
| a non-infinity value. This changes the stack allocation semantics in |
| subtle ways. For example, GNU make changes its stack allocation to the |
| hard maximum defined by _STK_LIM_MAX. As a results, threads executed |
| by processes running under make are allocated a stack size of |
| _STK_LIM_MAX rather than a sensible default value. This causes various |
| thread stress tests to fail when they can't muster more than about 50 |
| threads. |
| |
| The attached change implements the default behavior used by the |
| majority of architectures. |
